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.
