Description

Migrated from [DBZ-4729](https://issues.redhat.com/browse/DBZ-4729)

Support Capped Streams in debezium

[https://redis.io/commands/xadd#capped-streams]

[https://github.com/debezium/debezium/pull/3221]

 

Supporting capped streams will allow the user to control how many messages (events) a stream can have. This is important for clients that have a lot of streams/events coming through and they you want to control the amount of memory you used in Redis. Redis tries to store all data in memory but if your events are causing Redis to hit the `maxmemory` limit, this can cause Redis to start deleting keys or disable writes (depending on your maxmemory-policy).
