Hi Team,
I would like to know which backup&restore tools will be better for scenarios where the database is generating around 400 WALs per minute.
If my math is correct, 400x 16MB WAL files per minute is 400*(16*2^20)/60*8 / 10^6 = 895 MBits
per second. Plus overhead.
That's about
1Gbit/second. Definitely nothing to sneeze at.
We are using wal-g but it is not able to keep pace with the wal generation. We increased the upload streams to 256 but no luck
Uploads to a
remote server?
Does wal-g compress files before sending them across the wire? By how much? Are you CPU or IO bound by having to compress that much data?
