Best Practices for a Smooth Data Warehouse Migration to Amazon Redshift

In the era of big data, many organizations find themselves outgrowing traditional on-premise data warehouses. Moving to a scalable, cloud-based solution like Amazon Redshift is an attractive solution for companies looking to improve performance, cut costs, and gain flexibility in their data operations. However, data warehouse migration to AWS, particularly to Amazon Redshift, can be complex, involving careful planning and precise execution to ensure a smooth transition. In this article, we’ll explore best practices for a seamless Redshift migration, covering essential steps from planning to optimization.

1. Establish Clear Objectives for Migration

Before diving into the technical process, it’s essential to define clear objectives for your data warehouse migration to AWS. Are you primarily looking to improve performance, reduce operational costs, or increase scalability? Understanding the ‘why’ behind your migration will help guide the entire process, from the tools you select to the migration approach.

For instance, if your main goal is to reduce costs, you’ll want to explore Amazon Redshift’s pay-as-you-go model or even Reserved Instances for predictable workloads. On the other hand, if performance is your focus, configuring the right nodes and optimizing queries will become a priority.

2. Assess and Prepare Your Data

Data assessment is a critical step in ensuring that your Redshift data warehouse can support your needs post-migration. Start by categorizing your data to determine what should be migrated and what can be archived or discarded. AWS provides tools like the AWS Schema Conversion Tool (SCT), which helps assess and convert your existing data schema for compatibility with Amazon Redshift.

For structured data that fits into Redshift’s SQL-based architecture, SCT can automatically convert schema from various sources, including Oracle and SQL Server, into a Redshift-compatible format. However, data with more complex structures might require custom ETL (Extract, Transform, Load) processes to maintain data integrity.

3. Choose the Right Migration Strategy

Amazon Redshift offers several migration strategies, each suited to different scenarios:

Lift and Shift: This approach involves migrating your data with minimal adjustments. It’s quick but may require optimization post-migration to achieve the best performance.

Re-architecting for Redshift: This strategy involves redesigning data models to leverage Redshift’s capabilities, such as columnar storage and distribution keys. Although more complex, it ensures optimal performance and scalability.

Hybrid Migration: In some cases, you may choose to keep certain workloads on-premises while migrating only specific data to Redshift. This strategy can help reduce risk and maintain critical workloads while testing Redshift’s performance.

Each strategy has its pros and cons, and selecting the best one depends on your unique business needs and resources. For a fast-tracked, low-cost migration, lift-and-shift works well, while those seeking high-performance gains should consider re-architecting.

4. Leverage Amazon’s Native Tools

Amazon Redshift provides a suite of tools that streamline and enhance the migration process:

AWS Database Migration Service (DMS): This service facilitates seamless data migration by enabling continuous data replication with minimal downtime. It’s particularly helpful for organizations that need to keep their data warehouse running during migration.

AWS Glue: Glue is a serverless data integration service that can help you prepare, transform, and load data into Redshift. It’s particularly valuable when dealing with unstructured or semi-structured data that needs to be transformed before migrating.

Using these tools allows for a smoother, more efficient migration while reducing the risk of data inconsistencies and downtime.

5. Optimize for Performance on Amazon Redshift

Once the migration is complete, it’s essential to take advantage of Redshift’s optimization features:

Use Sort and Distribution Keys: Redshift relies on distribution keys to define how data is stored across nodes. Selecting the right key can significantly improve query performance. Sort keys, on the other hand, help speed up query execution by reducing disk I/O.

Analyze and Tune Queries: Post-migration, analyze your queries to identify potential bottlenecks. Redshift’s query optimizer can help tune performance based on your specific workloads, reducing processing time for complex queries.

Compression and Encoding: Amazon Redshift offers automatic compression, reducing the size of your data and enhancing performance. Using columnar storage, Redshift efficiently compresses data, so be sure to implement optimal compression settings to save storage costs and boost query speed.

Using Amazon Data Firehose For Iceberg Table Replication

Amazon Data Firehose

Dependable real-time stream loading into analytics services, data lakes, and warehouses.

Capturing, transforming, and loading streaming data is simple. With a few clicks, you can create a delivery stream, choose your destination, and begin streaming data in real time.

Provide and scale network, memory, and processing resources automatically without constant management.

Without creating your own processing pipelines, you may dynamically segment streaming data and convert raw streaming data into formats like Apache Parquet.

How it operates

The simplest method for obtaining, transforming, and sending data streams to analytics services, data lakes, and data warehouses in a matter of seconds is offered by Amazon Data Firehose. Setting up a stream with a source, destination, and necessary modifications is necessary in order to use Amazon Data Firehose. The stream is continuously processed by Amazon Data Firehose, which scales automatically according to the volume of data available and provides it in a matter of seconds.

Source

Choose your data stream’s source, such as a stream in Kinesis Data Streams, a topic in Amazon Managed Streaming for Kafka (MSK), or write data using the Firehose Direct PUT API. You can build up a stream from sources like Amazon CloudWatch Logs, AWS WAF web ACL logs, AWS Network Firewall Logs, Amazon SNS, or AWS IoT because Amazon Data Firehose is connected into more than 20 AWS services.

Data Transformation (optional)

Choose whether you wish to decompress the data, execute custom data transformations using your own AWS Lambda function, convert your data stream into formats like Parquet or ORC, or dynamically partition input records based on attributes to send into separate places.

The destination

Choose a destination for your stream, such as Splunk, Snowflake, Amazon Redshift, Amazon OpenSearch Service, Amazon S3, or a custom HTTP endpoint.

Use cases

Flow into warehouses and data lakes

Without creating processing pipelines, stream data into Amazon S3 and transform it into the formats needed for analysis.

Increase security

Use supported Security Information and Event Management (SIEM) solutions to keep an eye on network security in real time and generate warnings when possible threats materialize.

Create applications for ML streaming

To evaluate data and forecast inference endpoints as streams go to their destination, enhance your data streams with machine learning (ML) models.

Use Amazon Data Firehose to replicate database updates to Apache Iceberg tables (in preview)

A new feature in Amazon Data Firehose that records modifications made to databases like PostgreSQL and MySQL and replicates the changes to Apache Iceberg tables on Amazon Simple Storage Service (Amazon S3) is being made available in preview today.

An excellent open-source table format for large data analytics is Apache Iceberg. Open-source analytics engines like Apache Spark, Apache Flink, Trino, Apache Hive, and Apache Impala can operate with the same data simultaneously with Apache Iceberg, which also adds the simplicity and dependability of SQL tables to S3 data lakes.

This new feature offers a straightforward, end-to-end way to stream database updates without affecting database applications’ transaction performance. To transmit change data capture (CDC) updates from your database, you can quickly set up a Data Firehose stream. Data from various databases can now be readily replicated into Iceberg tables on Amazon S3, allowing you to access current data for machine learning (ML) and large-scale analytics applications.

Typical Enterprise clients of Amazon Web Services (AWS) utilize hundreds of databases for transactional applications. They wish to record database changes, such as the addition, modification, or deletion of records in a table, and send the updates to their data warehouse or Amazon S3 data lake in open source table formats like Apache Iceberg so that they can do large-scale analytics and machine learning on the most recent data.

Many clients create extract, transform, and load (ETL) processes to read data from databases on a regular basis in order to accomplish this. However, batch tasks can cause many hours of delay before data is ready for analytics, and ETL readers affect database transaction speed. Customers seek the option to stream database changes in order to lessen the impact on database transaction performance. A change data capture (CDC) stream is the name given to this stream.

Installing and configuring several open-source components is necessary for the initial setup and testing of such systems. Days or weeks may pass. The operational overhead is increased by the engineers’ need to validate and implement open source updates, monitor and manage clusters after setup.

CDC streams from databases can now be continuously replicated to Apache Iceberg tables on Amazon S3 using Amazon Data Firehose’s new data streaming feature. A Data Firehose stream is created by defining its source and destination. An initial data snapshot and all ensuing modifications made to the chosen database tables are captured and continuously replicated by Data Firehose as a data stream. Data Firehose minimizes the impact on database transaction performance by using the database replication log to obtain CDC streams.

AWS Data Firehose automatically splits the data and keeps records until they are sent to their destination, regardless of how frequently the number of database updates changes. Cluster management and fine-tuning, as well as capacity provisioning, are optional. As part of the initial Data Firehose stream creation, Data Firehose can automatically generate Apache Iceberg tables with the same schema as the database tables in addition to the data itself. It can also dynamically develop the target schema, adding additional columns, for example, in response to changes in the source schema.

You don’t need to use open source components, install software upgrades, or pay for overhead because Data Firehose is a fully managed service.

Amazon Data Firehose offers a straightforward, scalable, end-to-end managed solution for delivering CDC streams into your data lake or data warehouse, where you can execute extensive analysis and machine learning applications. It does this by continuously replicating database updates to Apache Iceberg tables in Amazon S3.

Things to be aware of

Here are some other things to be aware of.

The following databases on Amazon RDS and self-managed PostgreSQL and MySQL databases on Amazon EC2 are supported by this new feature:

Amazon Aurora PostgreSQL-Compatible Edition with Amazon RDS for PostgreSQL

Amazon Aurora MySQL-Compatible Edition with Amazon RDS for MySQL

Throughout the trial period and beyond general availability, the team will keep adding support for other databases. They informed me that support for MongoDB, Oracle, and SQL Server databases is already in the works.

Data Firehose connects to databases in your Amazon Virtual Private Cloud (Amazon VPC) via AWS PrivateLink.

You have two options when configuring an Amazon Data Firehose delivery stream: you may define a class of tables and columns using wildcards, or you can specify particular tables and columns. When using wildcards, Data Firehose will automatically construct new tables and columns in the destination if they match the wildcard and are added to the database after the Data Firehose stream is created.

Accessibility

With the exception of the Asia Pacific (Malaysia), AWS GovCloud (US), and China regions, all AWS regions now offer the new data streaming feature.

Amazon Data Firehose pricing

At the start of the preview, there are no fees for your use. In the future, the price will be determined by your actual usage, such as the number of bytes read and supplied. There are no upfront costs or obligations. To learn more, be sure to read the pricing page.

Important Amazon Redshift supplied cluster concepts:

Cluster: A cluster is an essential part of an Amazon Redshift data warehouse’s infrastructure.

A cluster has compute nodes. Compiled code runs on compute nodes.

An additional leader node controls two or more computing nodes in a cluster. Business intelligence tools and query editors communicate with the leader node. Your client application only talks to the leader. External apps can see computing nodes.

Database: A cluster contains one or more databases.

One or more computing node databases store user data. SQL clients communicate with the leader node, which organizes compute node queries. Read about compute and leader nodes in data warehouse system design. User data is grouped into database schemas.

Amazon Redshift is compatible with other RDBMSs. It supports OLTP functions including inserting and removing data like a standard RDBMS. Amazon Redshift excels at batch analysis and reporting.

Amazon Redshift’s typical data processing pipeline and its components are described below.
