![]() ![]() This is typically done to provide more flexible analytical capabilities, or when migrating from legacy data warehouses. Change data capture and database migration: AWS Database Migration Service (DMS) can be used to replicate changes in an operational data store into Amazon Redshift. ![]() This makes it a popular choice for data-driven applications, which might use data for reporting or perform calculations on it. Production workloads: Redshift’s performance is consistent and predictable, as long as the cluster is adequately-resourced.Redshift’s data sharing, search, and aggregation capabilities make it viable for these scenarios, as it allows exposing only relevant subsets of data per customer while ensuring other databases, tables, or rows remain secure and private. Embedded analytics and analytics as a service: Some organizations might choose to monetize the data they collect by exposing it to customers.Redshift is often used as the underlying database for BI tools such as Tableau (which otherwise might struggle to perform when querying or joining larger datasets). BI and analytics: Redshift’s fast query execution against terabyte-scale data makes it an excellent choice for business intelligence use cases.This can then feed enterprise-wide reporting and analytics. Redshift can be used as a centralized repository that stores data from different sources in a unified schema and structure to create a single source of truth. Enterprise data warehouse: Even smaller organizations often work with data from multiple sources such as advertising, CRM, and customer support. ![]() Some common use cases for Redshift include: Redshift’s Postgres roots mean it is optimized for online analytical processing (OLAP) and business intelligence (BI) – typically executing complex SQL queries on large volumes of data rather than transactional processing which focuses on efficiently retrieving and manipulating a single row. However, Redshift remains a very popular choice and is tightly integrated with other services in the AWS cloud ecosystem.Īmazon continues to improve Redshift, and in recent years has introduced federated query capabilities, serverless, and AQUA (hardware accelerated cache). A few notable products including Snowflake and Google BigQuery. Today, many modern cloud data warehouses offer similar linear scaling and infrastructure-as-a-service functionality. The ability to add compute resources automatically with just a few clicks or lines of code, rather than having to set up and configure hardware, was revolutionary and allowed for much faster application development cycles. As a fully managed service, Redshift allowed development teams to shift their focus away from infrastructure and toward core application development. When Redshift was first launched, it represented a true paradigm shift from traditional data warehouses provided by the likes of Oracle and Teradata. Scaling and managing clusters can be done through the Redshift console, the AWS CLI, or programmatically through the Redshift Query API. This also depends on the number of queries being executed, and the desired performance. It does this automatically.ĭetermining cluster size depends on the amount of data stored in your database. When a query is executed, Redshift’s MPP design means it distributes the processing power needed to return the results of an SQL query between the available nodes. Each cluster consists of a leader and compute nodes. ![]() What is a Redshift Cluster?Ī Redshift cluster represents a group of nodes provisioned as resources for a specific data warehouse. This includes massively parallel processing (MPP) and read-optimized columnar storage. Under the hood, various optimizations are implemented to provide fast performance even at larger data scales. Redshift is based on PostgreSQL 8.0.2 and supports standard SQL for database operations. Today Redshift is used by thousands of customers, typically for workloads ranging from hundreds of gigabytes to petabytes of data. What is Amazon Redshift?Īmazon Redshift is a fully managed cloud data warehouse offered by AWS. We’ll also discuss the limitations and scenarios where you might want to consider alternatives. In this article, we’ll cover the key facts you need to know about this cloud data warehouse, and the use cases it is best suited for. Start Running SQL on your Data LakehouseĪmazon Redshift is one of the most widely-used services in the AWS ecosystem, and is a familiar component in many cloud architectures. ![]()
