## What is the purpose of the change At the moment, we allow zero value for the TTL incremental cleanup size. Although technically zero value will not break the cleanup but practically there will be no cleanup. We change cleanupSize to be strictly greater than zero to avoid confusion.   -- This is an automated message from the Apache Git Service.
