MAP_PARALLELISM
Valid for
Parallel Replicat
Description
Configures number of mappers. It controls the number of threads used to read the trail file. The minimum value is 1, maximum value is 100 and the default value is 2. Increasing this parameter directly impacts the trail files. On a physical disk drive, you will start seeing IO contention if you use more than 4 or 5 mappers. If it’s in solid state, you can increase the value a bit higher before seeing IO contention. However, this depends on how much IO contention you need.
