 * use adminClient to check kafka ready? or retry sending message?
 
 * kafka: is static membership (group.instance.id) useful within stateful set?
 
-* log: use es data stream + ILM to rotate index? and is time series data stream (TSDS) useful (only for metrics data)
-  > not able to close index, only delete, and can simplify log processor and ES interface (no need to support "index" param in all requests)

 * db: update "on duplicated key" values() syntax,
   > The use of VALUES() to refer to the new row and columns is deprecated beginning with MySQL 8.0.20, and is subject to removal in a future version of MySQL.
