![]() ![]() Etleap transforms these events according to user-specified rules, and writes them to another data stream. These events are written to a Kinesis data stream that has multiple shards in order to handle the event load. The data flow is shown in the following diagram.Įtleap manages the end-to-end data flow through AWS Database Migration Service (AWS DMS) and Kinesis Data Streams, and creates and schedules Amazon Redshift queries, providing up-to-date data.ĪWS DMS consumes the replication logs from the source, and produces insert, update, and delete events. To preview this feature, we ingest data from SQL databases such as MySQL and Postgres that support change data capture (CDC). This is where streaming ingestion comes in: by staging the data in Kinesis Data Streams rather than Amazon S3, Etleap can reduce data latency in Amazon Redshift to less than 10 seconds. Amazon Redshift load times are bottlenecked by COPY commands that move data from Amazon S3 into Amazon Redshift, as mentioned earlier. For many use cases, such as ad hoc queries and BI reporting, this latency time is acceptable.īut what about when your team demands more up-to-date data? An example is operational dashboards, where you need to track KPIs in near-real time. Data ingestion pipelines typically process batches every 5–60 minutes, so when you query your data in Amazon Redshift, it’s at least 5 minutes out of date. Use Amazon Redshift streaming ingestion with EtleapĮtleap pulls data from databases, applications, file stores, and event streams, and transforms it before loading it into an AWS data repository. With this process, you can now query near-real-time data from your Kinesis data stream through Amazon Redshift. Each refresh is incremental and massively parallel, storing its progress in each Kinesis shard in the system catalogs so as to be ready for the next round of refresh. In either case, it uses the IAM role associated with the stream. You can initiate it manually (via the SQL preceding command) or automatically via a scheduled query. We begin by creating an external schema referencing Kinesis using syntax adapted from Redshift’s support for Federated Queries: In this section, we walk through the steps to configure streaming ingestion. ![]() Configure Amazon Redshift streaming ingestion with SQL queriesĪmazon Redshift streaming ingestion uses SQL to connect with one or more Kinesis data streams simultaneously. The new feature enables you to ingest hundreds of megabytes of data per second and query it at exceptionally low latency-in many cases only 10 seconds after entering the data stream. Now, the native streaming ingestion feature in Amazon Redshift lets you ingest data directly from Kinesis Data Streams. This method incurs latencies in the order of minutes. Traditionally, you had to use Amazon Kinesis Data Firehose to land your stream into Amazon Simple Storage Service (Amazon S3) files and then employ a COPY command to move the data into Amazon Redshift. Amazon Redshift streaming ingestion with Kinesis Data Streams This reduces load times from minutes to seconds and helps you gain faster data insights. In this post, we show how Etleap customers are integrating with the new streaming ingestion feature in Amazon Redshift (currently in limited preview) to load data directly from Amazon Kinesis Data Streams. Automated issue detection pinpoints problems so data teams can stay focused on business initiatives, not data pipelines. A cloud-native platform that seamlessly integrates with AWS infrastructure, Etleap ETL consolidates data without the need for coding. Etleap ETL removes the headaches experienced building data pipelines. Tens of thousands of customers use Amazon Redshift to process exabytes of data per day and power analytics workloads.Įtleap is an AWS Advanced Technology Partner with the AWS Data & Analytics Competency and Amazon Redshift Service Ready designation. ![]() Amazon Redshift is a fully managed cloud data warehouse that makes it simple and cost-effective to analyze all your data using SQL and your extract, transform, and load (ETL), business intelligence (BI), and reporting tools. ![]()
