for an existing table on dynamo, we can enable streams. Is there a similar functionality to QLDB? I remember seeing in posts that Kinesis Data Streams integration with QLDB was in preview.
QLDB Streams is now available as a feature that allows changes made to the journal to be continuously written in near real time to a destination Kinesis Data Stream. QLDB stream writes the data to Kinesis Data Streams in three types of records: control, block summary, and revision details. Please find further details in the following developer guide.
