Hi folks! :-)
I'm about to bring up my brand new production server and I was
wondering if it's possible to calculate (approx.) the WAL directory
size.
I have to choose what's better in terms of cost vs. performance (we
are on Google Cloud Platform) between a ramdisk or a separate
persistent disk. Obviously ramdisk will be times faster disk, but
having a, say, 512 GB ramdisk will be a little too expensive :-)
Don't use a RAM-Disk for WAL! DON'T! NEVER!
OK OK OK, got the point...... :-)
You really need only some GB, if you are using Replication. Without
Replication 1 GB would be fine, even with replication. But it must be
realible!
I'll get what seems to be the minumum persistent disk in size among GCP,
10 GB. Thanks!
Andreas
