CHUNK_SIZE
Valid For
Parallel Replicat
Description
CHUNK_SIZE defines
                the memory size for transactions. It controls how large a transaction must be for
                parallel Replicat to consider it as large. When parallel Replicat encounters a
                transaction larger than this memory size, it will serialize it, resulting in
                decreased performance. However, increasing this value will also increase the amount
                of memory consumed by parallel Replicat.
