The following are the benefits of using parallel Replicat:

• Integrated Parallel Replicat enables heavy workloads to be partitioned automatically among parallel apply processes that apply multiple transactions concurrently, while preserving the integrity and atomicity of the source transaction. Both a minimum and maximum number of apply processes can be configured with the PARALLELISM and MAX_PARALLELISM parameters. Replicat automatically adds additional servers when the workload increases, and then adjusts downward again when the workload lightens.
• Integrated Parallel Replicat requires minimal work to configure. All work is configured within one Replicat parameter file, without configuring range partitions.
• High-performance apply streaming is enabled for integrated parallel Replicat by means of a lightweight application programming interface (API) between Replicat and the inbound server.
• Barrier transactions are coordinated by integrated parallel Replicat among multiple server apply processes.
• DDL operations are processed as direct transactions that force a barrier by waiting for server processing to complete before the DDL execution.
• Transient duplicate primary key updates are handled by integrated parallel Replicat in a seamless manner.
• Parallel Replicat can break a single large transaction into smaller chunks and apply those chunks in parallel. See SPLIT_TRANS_RECS for details.
