> Project: Sidecar for Apache Cassandra
> Issue Type: Improvement
> Components: CDC
> Reporter: Jyothsna Konisa
> Assignee: Jyothsna Konisa
> Priority: Major
> Fix For: 0.5
>
>
> A single BEGIN BATCH CQL statement that writes to a CDC-enabled table and a
> CDC-disabled table under the same partition key, in the same keyspace,
> produces one commit log Mutation spanning both tables (Cassandra groups batch
> writes this way at the storage-engine level, independent of CDC). CDC
> bridge's Schema.instance was only ever populated with CDC-enabled tables and
> when such a mixed-table Mutation was read from the commit log, we are seeing
> unknown table exception causing mutation loss.
