Documentation

Definition

In order to improve the performance of external data transfers, it makes sense to execute multiple jobs in parallel. When doing so, however, note that this increases the main memory workload. The block size determines the number of objects to be processed for each job. The larger the block size, the more records are processed for each job. Smaller block sizes allow parallel processing because the main memory requirement is smaller.

The optimal value depends on the user's hardware, parallel processing, the size of the sender structure, and other factors such as the maximum number of lock entries in a system. Sometimes using a certain block size can help to avoid exceeding this limit.
