Hi,
What is the correct way to make FoundationDB split process classes evenly among Availability Zones in AWS?
After reading the documentation I’ve tried the following:
Setup:
- 9 EC2 instances, 3 in each Availability Zone
- 3 storage servers (1 per AZ), 6 transaction log processes (2 per AZ) - all set in the
/etc/foundationdb/foundationdb.conf. - Replication mode single.
-
locality_zoneid = <AZ_ID>(e.g.eu-central-1a)
For some reason foundationdb picked 3 transaction logs only (probably is the default). I noticed that 2 were from same AZ.
My expectation was that the transaction logs would be picked 1 for each AZ (there are 3 in total in eu-central-1 region).
Was my expectation/configuration wrong perhaps?
The goal was that by default there is 1 transaction log per distinct locality_zoneid.
