The latest release of ksqlDB, a popular open-source data streaming platform, introduces several new features that improve its capabilities. The retention time for windowed aggregates can now be configured in the aggregation statement itself, allowing for more flexibility and control over storage space. Additionally, the grace period for late-arriving events in windowed computations can also be configured, enabling applications to handle delayed events more effectively. Furthermore, ksqlDB 0.8.0 introduces a new built-in function called LATEST_BY_OFFSET, which allows users to track the latest value of a column when aggregating events from a stream into a table. The release also includes improvements to the client and server API, making it easier for developers to work with ksqlDB. Other notable features include two new built-in functions, REGEXP_EXTRACT and ARRAY_LENGTH, as well as various bug fixes and other enhancements.
