What is Teradata?

Teradata is an enterprise data warehousing solution that provides high-performance analytics and data management on a Massively Parallel Processing (MPP) system. Teradata enables users/organizations to store, process, and analyze large volumes of data from various sources and formats.

Teradata was first founded in 1979 (~45 years ago) by Jack E. Shemer, Philip M. Neches, Walter E. Muir, Jerold R. Modes, William P. Worth, Carroll Reed, and David Hartke. Teradata pioneered the concept of MPP, which distributes data and queries across multiple nodes, each with its own processor, memory, and disk, to achieve high performance, scalability—and reliability. Teradata also introduced the concept of shared-nothing architecture, which minimizes data movement and contention among the nodes and maximizes the parallelism and efficiency of the system.

Teradata has evolved from an on-premises solution to a hybrid cloud solution, offering various deployment options, such as Teradata IntelliFlex, Teradata IntelliBase, Teradata Vantage, which evolved from the Teradata Database, and so much more offerings. Teradata supports various data types and formats, such as structured, semi-structured—and unstructured data, and provides various tools and services, such as Teradata Studio & Studio Express, Teradata Data Fabric, Teradata ClearScape Analytics, and Teradata Data Lab, to enable data manipulation, analysis, integration, and management.

—and much more!!

Snowflake utilizes a unique hybrid architecture that combines elements of shared disk and shared-nothing Snowflake architectures. In the storage layer, data is stored in a centralized location in the cloud, accessible by all compute nodes, similar to a shared disk architecture. However, the compute layer operates on a shared-nothing model, where independent compute clusters called virtual warehouses process queries independently.

For more details on what Snowflake is and how it works, you can read our previous article here.

Now, let's dive into the next section, where we will compare Teradata vs Snowflake across 7 different features.

Teradata vs Snowflake: 7 Critical Features You Need to Know

Teradata vs Snowflake—Which option best suits your requirements? Let's dive into the specifics and examine their essential features:

1). Teradata vs Snowflake—Architecture Breakdown

One of the most important features that distinguishes Teradata vs Snowflake is their architecture, which determines how they store, process, and access data. In this section, we will explain the architecture of each solution and compare and contrast their pros  and cons.

Now, let's explore their architectural differences.

Snowflake Architecture—Teradata vs Snowflake

Snowflake utilizes a unique hybrid cloud architecture that combines elements of shared disk and shared-nothing architectures. In the storage layer, data resides in a central data repository that is accessible to all compute nodes, like a shared disk. But the compute layer uses independent virtual warehouses that process queries in parallel, like a shared-nothing architecture.

The Snowflake architecture has three layers:

1) Storage Layer: Snowflake storage layer is designed to optimize data storage and accessibility. When data is loaded into Snowflake, it is converted into an optimized, compressed, columnar format. Snowflake stores this optimized data in cloud storage. Snowflake manages all aspects of how this data is stored—the organization, file size, structure, compression, metadata, statistics, and other aspects of data storage are handled by Snowflake. The data objects stored by Snowflake are neither directly visible nor accessible by the user; they are only accessible through SQL query operations run using Snowflake.

2) Compute Layer: Snowflake's compute processing layer utilizes virtual warehouses to execute each query. Each virtual warehouse is an MPP (massively parallel processing) compute cluster, consisting of multiple compute nodes allocated by Snowflake from a cloud provider. This distributed computing environment enables Snowflake to process large volumes of data quickly and efficiently. What's cool is that each virtual warehouse operates independently without sharing compute resources with other virtual warehouses.

3) Cloud Services Layer: Snowflake cloud services layer is like the control center that oversees everything in Snowflake. It's the brains connecting all the different pieces to process user requests, ranging from login to query dispatch. This layer manages various services, including authentication, infrastructure management, metadata management, query parsing, optimization—and access control.

Note that the cloud services layer runs on compute instances provisioned by Snowflake from the cloud provider.

Teradata Architecture—Teradata vs Snowflake

Teradata’s architecture is based on a massively parallel processing (MPP) system that integrates storage and compute nodes in a single system, meaning that Teradata distributes data and queries across multiple nodes, each with its own processor, memory, and disk, to achieve high performance, throughput, and reliability.

Teradata can handle massive data volumes, support complex workloads, and provide enterprise-grade performance at scale.

Let's do a deep dive into the various components that make up Teradata's robust MPP architecture.

The architecture of Teradata consists of five main components: Teradata Nodes, Parsing Engine BYNET, and AMP. Here is the high-level architecture of the Teradata Node.

Teradata Node Architecture - Teradata vs Snowflake
Teradata Node Architecture - Teradata vs Snowflake
1) Teradata Nodes

The basic building block of a Teradata system is a node. Each node is an individual server consisting of the following elements:

  • CPU: The central processing unit provides the computing capability. Each node will have multiple powerful CPUs.
  • Memory: Substantial RAM is provisioned for in-memory operations, caching, and temporary storage.
  • Storage: Disk storage is directly attached to each node for permanent storage of data.
  • Network: An interconnect facilitates high-speed communication between nodes.
  • Software: The Teradata database software and operating system is deployed on each node.

Multiple homogeneous nodes are interconnected to form a Teradata system. The number of nodes can scale into the hundreds to provide massive combined computing power and storage capacity.

2) Parsing Engine (PE)

Parsing Engine (PE) also known as a virtual processor (vproc), is a component in a Teradata system that handles communication with client applications and coordination of SQL processing. Each node has a Parsing Engine. The key responsibilities of the Parsing Engine are:

  • Receive queries from client applications
  • Parse and validate the SQL syntax
  • Check user privileges and object access
  • Generate an optimized execution plan
  • Pass the execution plan to the BYNET for distributed execution
  • Receive result rows and return to the client

The Parsing Engine processes the SQL and creates a plan for efficient execution by extracting parallelism in operations like scanning, filtering, aggregations, and joins.

TL;DR:
Parsing Engine acts as a communicator between the client system and AMP via BYNET.
3) BYNET (Message Passing)

BYNET is Teradata's messaging passing layer that connects the various components and facilitates intra-node communication. It routes messages between Parsing Engines and AMPs for query execution and result collection.

BYNET provides a high-speed, reliable, and efficient interconnect for passing requests, execution plans, data rows, and responses between nodes. It tracks the flow of messages across the system. BYNET allows massive parallelism by enabling multiple thousands of AMPs to coordinate.

4) Access Module Processors (AMPs)

Access Module Processors (AMPs) are the workhorses for data storage and processing in Teradata. There can be hundreds of AMPs across multiple nodes working together. AMPs perform the following key functions:

  • Store row data across attached disk storage
  • Receive execution plans from BYNET and extract operations
  • Perform scans, filters, aggregations, sorting, joins and other data operations
  • Send result rows back to BYNET for collection.

AMPs run in their own portion of memory and utilize available CPUs for data processing. BYNET distributes incoming queries to relevant AMPs holding the target tables and data involved. Each AMP has dedicated access to its attached storage for read and write operations.

5) Virtual Disks (Vdisks)

Vdisks are units of storage space owned by an AMP. Virtual Disks are used to hold user data (rows within tables). Virtual Disks map to physical space on a disk.

6) Parallel Database Extension (PDE)

Parallel Database Extension (PDE) provides APIs for various OS to interact with Teradata Node. The operating system (OS) can be MP-RAS, Linux, or Microsoft Windows operating systems.

Teradata Storage Architecture

Teradata uses a shared-nothing storage architecture where the entire data is evenly divided into chunks and distributed across all the AMPs. When new data is added through INSERT statements, the Parsing Engine passes the rows to BYNET which allocates them evenly to AMPs.

A hashing algorithm assigns rows to AMPs to ensure uniform distribution. Each AMP stores its rows on its locally attached disks as data blocks. This architecture eliminates storage bottlenecks since large datasets can be divided and stored in parallel across hundreds of AMPs and disks.

During retrieval, BYNET routes incoming queries to the relevant AMPs that contain the target tables. The AMPs scan and process the data blocks in parallel and pipe back qualifying rows through BYNET to the Parsing Engine.

TL;DR:

  • Client application issues SQL INSERT statement to load data into a Teradata table
  • Parsing Engine parses the statement, creates plan and sends insert request to BYNET
  • BYNET routes the incoming rows to appropriate AMPs based on hash of primary index value
  • Each AMP inserts its portion of rows into its managed physical storage
  • AMPs acknowledge success back to Parsing Engine after commits

Teradata Query Processing Architecture (Retrieval Architecture)

During query processing, BYNET and AMPs retrieve data in parallel:

  • Client sends a query request to Parsing Engine (PE).
  • PE generates a plan and passes to BYNET.
  • BYNET routes requests to relevant AMPs based on data location.
  • AMPs scan their local data in parallel and return qualifying rows.
  • BYNET transfers rows back to the PE.
  • PE does any final aggregation and returns results.

All AMPs work concurrently on local data partitions. BYNET handles transferring rows between AMPs for additional processing like sorting, joining, aggregating, etc. The parallel architecture minimizes response times for even the most complex queries.

This powerful design can handle heavy workloads, massive data volumes, and concurrency levels that would overwhelm traditional databases.

2).  Teradata vs Snowflake—Performance & Scalability

When it comes to sheer query performance, both Snowflake and Teradata can provide extremely fast response times. However, they achieve high performance through different architectural approaches.

Snowflake Performance & Scalability—Teradata vs Snowflake

One of the most revolutionary innovations from Snowflake is the total separation between storage and compute. Snowflake's storage layer runs on low-cost object storage from major cloud providers like AWS, Azure, and GCP. The storage is effectively infinite and decoupled from compute.

Snowflake then uses clusters of virtual warehouses to provide the compute power for running queries. These virtual warehouses can scale up and down instantly. More importantly, they scale independently from storage.

This architecture is the key reason why Snowflake offers such incredible query performance. Users can spin up as many virtual warehouses as needed for massive parallel query processing. Snowflake can literally throw hundreds of servers at a query to return results in seconds!

The scaling is also completely on-demand. Virtual warehouses can be spun up and shut down immediately. So you only pay for the compute you use. Snowflake is designed to leverage the cloud's virtually unlimited resources to deliver performance when you need it.

Teradata Performance & Scalability—Teradata vs Snowflake

Teradata, on the other hand, relies on a more traditional scale-up approach to achieve high performance. It runs on an MPP shared-nothing architecture with intelligent data distribution and parallel processing across multiple nodes.

Each Teradata node contains CPUs, memory, storage, and networking. Queries are decomposed into steps and distributed across nodes for parallel execution. Teradata can achieve excellent performance by scaling up the number of nodes and the specifications of each node.

But there are more upper limits in Teradata vs Snowflake's cloud-native architecture. The network interconnect bandwidth, storage capacity, and number of nodes define the performance boundaries.

That said, Teradata has 45 years of expertise in optimizing complex queries and workloads. It has mature query optimization, indexing, data compression, and workload management capabilities. For many existing EDW use cases, Teradata can match Snowflake's raw speed through sheer engineering prowess.

The Choice Depends on Your Workload.

So to sum it up, both Snowflake and Teradata are capable of top-notch query performance. Snowflake provides virtually unlimited scale-out capabilities, leveraging the cloud. Teradata relies on scale-up and deep optimization.

For newer cloud-based projects with unpredictable workloads, Snowflake is hard to beat. But existing complex EDWs may benefit by staying on Teradata while migrating to the cloud. The optimal choice depends heavily on each organization's specific technical environment, workload patterns, and cost considerations.

3). Teradata vs Snowflake—Workload Configuration & Management

For any large business/organization, the data warehouse needs to handle a diverse mix of workloads—from ad hoc analytics to user dashboards, ETL data loads, query tuning tasks and more. Both of ‘em Teradata vs Snowflake are mature enough to handle multiple concurrent workloads efficiently. However, their approaches reflect their different architectures.

Snowflake Workload Config & Management—Teradata vs Snowflake

Snowflake's architecture sets it apart when it comes to workload management. Its storage layer is centralized but completely separate from compute. The virtual warehouses provide all the query processing power.

Snowflake allows creating multiple virtual warehouses for each logical workload.

Each cluster can be scaled up and down independently based on its usage. New clusters can be spun up instantly to isolate new workloads. Snowflake provides seamless workload isolation and "infinite" processing power through its multi-cluster architecture.

Snowflake also offers Workload Management and monitoring tools. Admins can define workload management rules to control concurrency, queuing policies, and allotted credit limits for different user groups and workloads.

Teradata Workload Config & Management—Teradata vs Snowflake

Unlike Snowflake’s independent workload silos, Teradata uses a holistic workload management approach. All concurrent queries and operations go through a centralized, closed-loop workload manager.

Sophisticated algorithms schedule and prioritize queries to optimize overall throughput and service levels. The workload manager assembles queries into dispatch windows to maximize system resources like AMPs, BYNET, Vdisks, and CPUs.

Admins can define workload rules based on business SLAs. More important workloads get priority in resource allocation. Limits can be set for low-priority workloads to avoid impacting others. Teradata also offers tools like Data Fabric, QueryGrid and Viewpoint to monitor and tune workload performance.

The key difference between Teradata vs Snowflake is that Teradata actively optimizes and balances all workloads globally across the system. There is tighter coordination between workloads to maximize system utilization. It provides more "fine-tuned" management versus brute-force isolation and scaling.

4). Teradata vs Snowflake—Ecosystem & Integration

Teradata vs Snowflake: both of ‘em have extensive partnerships and integrations available.

Teradata Security & Governance—Teradata vs Snowflake

Over its 45+ year history, Teradata has built an extensive arsenal of  enterprise-grade security and governance practices to protect data and provide visibility into its usage.

Network and Encryption Security

Teradata secures communications via encryption and firewalls. Database traffic can be encrypted with AES, 3DES, or RC4 symmetric algorithms. SSL/TLS connections prevent man-in-the-middle attacks.

To prevent network eavesdropping, Teradata can encrypt specific requests or entire sessions. Data at rest can also be encrypted using solutions like Protegrity Database Protector. Backup archives can be encrypted using tape drive or deduplication system encryption.

Teradata's BYNET provides the secure interchange between different Terabyte nodes. BYNET handles authentication and access controls when transferring requests and data between nodes.

User Authentication

You can't protect your data without knowing who is accessing it. Teradata offers authentication methods to validate user identities:

  • LDAP integration allows central user authentication against Active Directory or other LDAP directories.
  • Kerberos support enables single sign-on so users don't reauthenticate to Teradata after network login.
  • Teradata can integrate with identity providers like SAML and OAuth for SSO across cloud applications.
  • Two-factor authentication/MFA adds an extra layer of identity verification for high-security environments.

Once users are authenticated, their access is restricted only to data they are authorized to see.

6). Teradata vs Snowflake—Supported Programming Languages

Whenever you are working with large-scale data platforms, it is important for data professionals to leverage familiar languages for various automation and analytics tasks. Both Snowflake and Teradata understand this need and support a wide variety of programming languages out of the box. Now, in this section, we will explore the different languages supported by each of these platforms.

Snowflake Programming Language Support—Teradata vs Snowflake

Snowflake supports developing applications using many popular programming languages and development platforms. Using native clients (connectors, drivers, etc.) provided by Snowflake, you can develop applications using any of the following programmatic interfaces:

  • ANSI SQL: Snowflake is built for SQL-first data processing and is fully ANSI SQL compliant. You can write complex queries, CTAS statements, temporal queries, array processing and more using standard SQL. You can also use ANSI SQL to interact with Snowflake from various tools and applications, such as SnowSQL (the Snowflake command-line client), Snowflake web interface, and third-party SQL clients.
  • User-Defined Functions (UDFs): Snowflake allows you to create and execute user-defined functions (UDFs) that extend the functionality of Snowflake and perform custom logic on your data. You can create UDFs using the following languages:
  • JavaScript
  • Python
  • Java
  • Scala
  • SQL UDFs
  • REST API: Snowflake also exposes a robust REST API allowing HTTP requests for all warehouse operations from any language via simple GET/POST calls.

Teradata Programming Language Support—Teradata vs Snowflake

Unlike Snowflake's more open-ended approach, Teradata takes a pragmatic path:

  • Teradata primarily relies on widely used languages like C/C++, Java, Python, Go, and R for stored procedures and UDFs.
  • It also supports traditional languages like COBOL, Fortran, Perl, and Ruby, used heavily in enterprises.
  • SQL support is ANSI compliant. SQL stored procedures can contain control flow logic.
  • JSON and XML data types are also natively supported in Teradata.
  • Connectors are also supported which allow accessing Teradata data from outside tools like R, Matlab, SAS, TensorFlow, and PyTorch.

No matter your language preference, both Teradata and Snowflake have you covered.

7). Teradata vs Snowflake—Indexing

Indexes are a fundamental mechanism for optimizing database performance. By creating indexes on one or more columns of a table, queries that filter or sort by those columns can be executed much faster. This is because indexes allow the database to quickly locate and retrieve only the relevant data without having to scan the entire table.

Different db/warehouse technologies take varying approaches to indexing. Let's examine how Teradata and Snowflake each tackle this important performance tuning aspect.

Snowflake Indexing—Teradata vs Snowflake

Snowflake has taken an unconventional stance by choosing not to support traditional indexes. In short, Snowflake does not use indexes to optimize queries. Instead, it leverages techniques/features like micro-partitioning, clustering keys, automatic clustering, and query pruning to deliver fast query performance.

Snowflake stores data in small micro-partitions, typically 50 MB to 500MB in size. Micro-partitions contain a subset of rows stored in a columnar format, which enables parallel processing and scanning only relevant data during queries.

Snowflake utilizes sophisticated query pruning techniques. Using stats on micro-partitions and query predicates, Snowflake determines which micro-partitions can be eliminated from scanning based on the query filter conditions. This minimizes the amount of data required for processing.

For further optimization, Snowflake can automatically cluster data by grouping related rows into the same micro-partitions. A clustering key defines the column(s) to cluster data on. Clustering improves pruning efficiency as related rows exist in fewer partitions.

On top of all this, Snowflake continuously analyzes comprehensive query history and table statistics to adapt and optimize query execution plans over time. It determines the optimal approaches to process different query types and data shapes without manual tuning.

When you combine micro-partitions, intelligent optimization, clustering, and scale-out compute, Snowflake doesn't need traditional database indexes for most workloads!

Teradata Indexing—Teradata vs Snowflake

Given its longer history in data warehousing, Teradata uses a full-fledged indexing system to maximize performance. The main types of indexes it supports are:

1) Primary Indexes: A primary index is a unique, non-null column like a primary key that is used to uniquely identify each row in a table. Teradata uses primary indexes for efficient distribution, retrieval, and locking of data. Each table in Teradata must have at least one column as Primary Index. Primary index cannot be altered or modified.

There are two types of Primary Indexes:

  • Unique Primary Index (UPI).
  • Non-Unique Primary Index(NUPI)

2) Secondary Indexes: Secondary indexes allow non-unique queries against columns other than the primary key. They improve the access performance of queries using indexed columns. Secondary Index can be created or altered after the creation of the table. There are two types of Secondary Index:

  • Unique Secondary Index (USI).
  • Non-Unique Secondary Index (NUSI).

3) Join Indexes: These optimize access patterns for common join queries. They store pointers to rows matching join criteria rather than index column values. Note that defining the join index in Teradata does not imply that the parsing engine will always use the join index. It is up to Teradata parsing engine whether to use join index or access from the base table.

There are different types of join index in Teradata:

  • Single Table Join Index(STJI)
  • Multi Table Join Index(MTJI)
  • Aggregate Join Index
  • Sparse Join Index

4) Hash Indexes: Hash indexes distribute rows across partitions according to a hashing algorithm for very fast retrieval of exactly matching values. Hash index has been designed to improve the performance of Teradata query in a way similar to the Single Table Join Index, which restricts PE not to access or redistribute the base table.

Bonus: Teradata vs Snowflake—Billing & Pricing Models

Finally, Teradata and Snowflake distinctly vary in their pricing models. In this part, we will dive into the depth of "Teradata vs Snowflake" pricing to help you in making well-informed and cost-effective decisions for your data platform investment.

Snowflake pricing Breakdown—Teradata vs Snowflake

Snowflake uses a pay-per-usage pricing model based on actual usage, rather than fixed hourly or monthly fees. Users are charged by the second for the processing power used based on the size of the virtual warehouses (VW) deployed. Snowflake separates storage charges from compute. Storage is charged based on average monthly storage usage after compression.

Note: Snowflake does not charge data ingress fees to bring data into your account, but does charge for data egress

When it comes to pricing, Snowflake keeps things simple yet flexible. The cost is based on your usage of three key components:

1) Storage Costs

Let's break it down one piece at a time. First up is storage. This refers to how much data you have stored in Snowflake. Your monthly storage cost depends on the average amount of compressed data you use each month. Snowflake compresses your data, so you may put in 1TB but it takes up less space after compression—and you only pay for what's actually stored.

You've got two options for storage pricing.

  1. On-Demand: With the help of On-Demand, you pay a per GB rate each month based on usage. Rates vary by cloud platform and region. For example, On-Demand storage on AWS in the US East (Northern Virginia) is ~$40 per, whereas it's $45 per TB per month for those deployed in the EU region. Simple! You can calculate your cost yourself from here.
  2. Capacity Storage: The other option is Capacity pricing. Here you pre-pay for a chunk of storage upfront. This gets you better rates and a long-term price guarantee. The cost depends on your total commitment amount. Once your prepaid capacity runs out, you flip to On-Demand rates. Capacity pricing runs around $23-25 per TB in the US and EU.

2) Compute Costs

Next up is compute power for querying data, also known as “virtual warehouses”. You can choose from sizes like:

  • X-Small (extra small)
  • Small
  • Medium
  • Large
  • X-Large (extra large)
  • 2X-Large (2 times extra large)
  • 3X-Large (3 times extra large)
  • 4X-Large(4 times extra large)
  • 5X-Large(5 times extra large)
  • 6X-Large(6 times extra large)

Bigger warehouses pack more punch for complex queries. The credits required for compute scale-up as the warehouse size increases. An X-Small warehouse costs 1 credit per hour, while a 4X-Large is 128 credits per hour.

Smaller warehouses are far cheaper for basic queries. But bigger ones accelerate performance for tougher jobs, though not always proportionally. Scaling may hit diminishing returns. Workload tests help pick the optimal size.

The cool part is that compute billing is per second. When not querying, warehouses auto-stop, avoiding unused idle time charges. They restart instantly when you resume work. This on-demand model saves big versus always-on resources.

Here is the complete breakdown of credits used per warehouse size:

3) Cloud Services

Last but not least are cloud services. Cloud service layers offer multiple services like authentication, authorization, query calculation, SQL API, performance tuning, analytics security features—and much more. Because these features are provided by default, Snowflake does not charge users directly for them. But it will charge based on the specific condition. Snowflake automatically assigns cloud services based on the requirements of the workload. Typical utilization of cloud services, up to 10% of daily compute credits, is included for free, meaning most users and users won't see incremental charges for cloud service usage. Assume you have a virtual warehouse and have spent “A” credits. Consider cloud service layer credit to be “B” credit; if it is within 10% of the “A”, it will not be charged to the user; if it exceeds 10% of the daily computing credit, it will be charged to the user; otherwise, it will be free to use.

4) Data Transfer

Last but not least is data transfer. Snowflake calculates data transfer costs by considering criteria such as data size, transfer rate—and the region or cloud provider from where the data is being transferred.

Snowflake data transfer cost structure depends on two factors: ingress and egress.

Ingress, means transferring the data into Snowflake. It is free of charge. Data egress, however, or sending the data from Snowflake to another region or cloud platform incurs a certain fee. If you transfer your data within the same region, it's usually free. When transferring externally via external tables, functions, or Data Lake Exports, though, there are per-byte charges associated that can vary among different cloud providers.

Take a look at some Snowflake pricing tables for comparison to get an idea of what the difference in cost could look like:

Snowflake Pricing Plan Editions

Snowflake also offers four editions with different features and pricing:

1) Standard Plan

2) Enterprise Plan

3) Business Critical Plan

4) Virtual Private Snowflake
