Detailed Description

Write dynamic metadata to DD buffer table immediately when such data is generated.

By default, the metadata is first written to redo log and then to the DD buffer table during checkpoint. This is going to hurt auto increment performance and Currently enabled by clone for short time to eliminate dependency with dynamic metadata recovered from redo log.
