Hama,
I can’t understand your comment: “it was what I expected using bookkeeper”

BookKeeper is used as commit log, it does not impact reads at all, we are never reading from the commit log, only in case of recovery.
Writes pass thru BK and Read flow thru FileDataManager

Hi,
I remaked the bench using Bookeeper wall,
I didn't see any problems or regression compared with standalone wall.
Compared with mysql 5.7 we are very fast more in Read mode ( it was what I expected using bookkeeper).
