Hi,
I'm reading this document:
I have 3 questions:
1. BlueStore writes both data (to raw block device) and metadata (to RockDB) simultaneously, or sequentially?
2. From my opinion, performance of BlueStore can not compare to FileStore using SSD Journal, because performance of raw disk is less than using buffer. (this is buffer purpose). How do you think?
3. Do setting Rock DB and Rock DB Wal in SSD only enhance write, read performance? or both?
Hope your answer,
