Configuring replication batch size


GSC shows repeated warnings when replicating from Primary to Backup: "replicating a packet which is bigger than the batch size, [packet key=3084183, packet weight=1162, backlog batch size = 1000]"

Looks like we should slightly increase the replication batch size. What is the name of the relevant configuration property?

Hi, During recovery from primary the relevant property is cluster-config.groups.group.repl-policy.recovery-chunk-size For async replication its cluster-config.groups.group.repl-policy.async-replication.repl-chunk-size The warning means you have a transaction with 1162 operations while chunk size is 1000, we will not break the transaction but rather not honor the batch size limit.

Regards, Ester.
