I’m thinking about storage and would be interested on what others think.
I was planning to have the wal stored on a RamDisk.
This would be fast. Using RamDisk which as I understand can be written to many more times than a SDD, prolonging the life of the SDD (if it was used instead). I realise that during a power failure the wal would be lost and I am ok with this. Some RamDisks can however store their contents on a managed power down.
If I lost the wal and rebooted would I just have missing series data or would their be other issues?
Saving the Data location on a SDD or HDD
There appears to be no real advantage as to which I use here. It isn’t continually written to the same location on memory/disk and then deleted, so wear isn’t an issue.
