bluestore doesn't have a journal like the filestore does, but there is the WAL (Write-Ahead Log) which is looks like a journal but works differently.
You can (or must, depending or your needs) have SSDs to serve this WAL (and for Rocks DB).

Folks,
I'm just reading from multiple post that bluestore doesn't need SSD journel, is that true?
I'm planning to build 5 node cluster so depending on that I purchase SSD for journel.
If it does require SSD for journel then what would be the best vendor and model which last long? Any recommendation
