How to optimizing table-table join on ksqlDB?

ksqlDB
1

Hello,

I would like to know how to optimize speed of table-table join during monitoring I saw this hop is mostest messages lag so i prefer to increase speed of this hop.

I found some properties as following but I not sure that will help or not.

  1. set up ksql.streams.num.stream.threads same as number of partition
  2. set max.partition.fetch.bytes to increase sizing for ksqlDB query able to consume per partition per fecth.
  3. set cache.max.bytes.buffering
  4. increase number of partition

Please help me to share about your experience about tuning hop joining on ksqlDB.

Thanks
May R.
