> CDC reader in Apache Cassandra Sidecar
> --------------------------------------
>
> Key: CASSANDRASC-27
> URL: https://issues.apache.org/jira/browse/CASSANDRASC-27
> Project: Sidecar for Apache Cassandra
> Issue Type: New Feature
> Reporter: Vinay Chella
> Assignee: maxwellguo
> Priority: Normal
>
> 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
>
> *Proposal*
