MyRocks File Hints

MySQL & MariaDB Percona Server for MySQL 8.0
1

Hi, does MyRocks sends file hints during compaction automatically or we have to configure that?

I am running Sysbench/Percona MySQL/MyRocks with io_uring. Want to make sure MyRocks Hints are getting passed to io_uring and then passed to the block layer. The file Hints I am referring to are Hot, Medium, Cold, and Extreme. Thank you.

Hello @Jay_Rafati,
This is all I could find:

  • rocksdb_use_io_uring – Enable io_uring for asynchronous I/O.

Seems to be just on/off. You’d have to look at the source code for more information.
