Can oap-server support multipart storage config

[807801002]

I want to write metric data to multipart db, just as ES7 for oap-server query for UI, and MySQL for grafana query or bin log subscribe to synchronize real time to graph db to analyze multipart step data. Can oap server support it?

No, this makes no sense. Grafana could read ElasticSearch too. There is no point to duplicate storage load, and provide nothing more, but more risk for inconsistent data.

Grafana query es data is difficult to handle the time bucket field,which is saved as long type and not a timestamp. and es is difficult to handle join query. Can I add insert MySQL at MetricESDAO#prepareBatchInsert and MetricESDAO#prepareBatchUpdate to make it?

No, upstream wouldn't accept it. The reason is very clear.
About the timestamp, yes, it hasn't been supported. But that is a simple feature, if someone wants to contribute, a new extra field could be added, like literal names added.
