Vinay Chella updated CASSANDRASC-27:
------------------------------------
    Description: 
Apache Cassandra has the CDC (Change Data Capture) features since 3.8. This is 
further enhanced with (CASS-12148) in Cassandra 4.0.

However, there’s no generally available mechanism to stream changes out of a 
Cassandra database; hence the utility of this feature is limited if not absent.

Many applications use Cassandra as their primary data store. For various 
reasons(Caching, analyzing, indexing, etc), this data needs to be synchronized 
with derived/secondary data stores.  We would like to emit change streams in 
real-time to consumers so that changes to Cassandra can be used for various 
purposes.

*Goals*
 * Enhance Apache Cassandra sidecar with a CDC reader that can read and emit 
changes in real-time. Priority for the initial implementation is safety and 
correctness, performance enhancements will follow in subsequent iterations

*Nongoals*
 * Modify Cassandra storage engine to emit changes
