Couchbase has introduced a new "External Datasets" feature in its latest Server 6.6 release, allowing users to access and analyze data stored in Amazon Web Services (AWS) Simple Storage Service (S3) in real-time. This feature enables the integration of S3-resident data with existing Couchbase data for analytics, meeting the needs of customers who store large volumes of historical data and business data on S3 for cost efficiency. By setting up an S3 link, creating an external dataset, and using SQL++ for queries, users can dynamically combine and analyze data from both Couchbase and S3 without needing extensive ETL processes. The feature supports various file formats like JSON and CSV, allowing for flexible data enrichment and dynamic access through massively parallel processing, ultimately facilitating faster and more comprehensive data analysis and decision-making.
