ASF GitHub Bot updated CASSANDRASC-27: -------------------------------------- Labels: pull-request-available (was: ) > 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: Tharanga Sampath Gamaethige > Priority: Normal > Labels: pull-request-available > > 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* > [https://docs.google.com/document/d/11YywfJTm29szZOVOSRbtfvClbmMQtJ8WyCB7_CUgo-U/edit?usp=sharing] > > *PR* > https://github.com/apache/cassandra-sidecar/pull/16 > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
