After that, using materialized-view refresh, you can ingest hundreds of megabytes of data per second. You can create materialized views using SQL statements. It’s simple to set up, and directly ingests streaming data into your data warehouse from Amazon Kinesis Data Streams and Amazon Managed Streaming for Kafka ( Amazon MSK) without the need to stage in Amazon Simple Storage Service (Amazon S3). Redshift streaming ingestion provides low latency, high-throughput data ingestion, which enables customers to derive insights in seconds instead of minutes. This post showcases how to use streaming ingestion to bring data to Amazon Redshift. To gain deeper and richer insights, you can bring all the changes from different data silos into one place, like data warehouse. Data silos causes data to live in different sources, which makes it difficult to perform analytics. With the explosion of data, the number of data systems in organizations has grown. When the CDC is high-frequency, the source database is changing rapidly, and the target database (i.e., usually a data warehouse) needs to reflect those changes in near real-time. A CDC-based approach captures the data changes and makes them available in data warehouses for further analytics in real-time.ĬDC tracks changes made in source database, such as inserts, updates, and deletes, and continually updates those changes to target database. Change Data Capture (CDC)-based approach has emerged as alternative to batch-based approaches. A batch-based approach can introduce latency in data movement and reduce the value of data for analytics. Batch load can run once or several times a day. Traditionally, customers used batch-based approaches for data movement from operational systems to analytical systems. We hear from our customers that they’d like to analyze the business transactions in real time.
