Hi: I am restoring a ~100GB backup using 16 jobs from an EC2 instance to an RDS instance (db.m6g.xlarge, which is 16GB RAM and 4 CPU) and it's dying midway with the dreaded "SSL SYSCALL error: EOF detected" error.
I did create a parameter group to hopefully speed the restoration process, it includes:
- wal_buffers 8192 (64MB)
- checkpoint_timeout 3600 (1h)
- min_wal_size 192 (192MB)
- max_wal_size 102400 (100GB)
- shared_buffers 524288 (4GB)
- synchronous_commit 0 (off)
- autovacuum 0 (off)
- maintenance_work_mem 2097152 (2GB)
- work_mem 32768 (32MB)
- checkpoint_timeout 3600 (1h)
- min_wal_size 192 (192MB)
- max_wal_size 102400 (100GB)
- shared_buffers 524288 (4GB)
- synchronous_commit 0 (off)
- autovacuum 0 (off)
- maintenance_work_mem 2097152 (2GB)
- work_mem 32768 (32MB)
I sourced these from a few different folks as well as some trial and error, but now it's blowing up on me.
If I revert the RDS instance back to default PG parameters, it restores, but it takes 3x the time.
Appreciate any tips.
