Configuring Maximum Parallelism for MapR-DB Mappings

Configuring Maximum Parallelism for MapR-DB Mappings

Configure maximum parallelism in one of the following ways for MapR-DB mappings that you want to run in the native environment or on the Blaze and Spark engines in the Hadoop environment:
Set a maximum parallelism value for a mapping in the Developer tool.
By default, the
Maximum Parallelism
 property for each mapping is set to
Auto
. Each mapping uses the maximum parallelism value defined for the Data Integration Service.
You can change the maximum parallelism value in the mapping run-time properties to define a maximum value for a particular mapping. When you set the maximum parallelism to different integer values for the Data Integration Service and the mapping, the Data Integration Service uses the minimum value of the two.
Ask the administrators to set the maximum parallelism for the Data Integration Service to a value greater than 1 in the Administrator tool.
Maximum parallelism determines the maximum number of parallel threads that process a single pipeline stage. Administrators can increase the
Maximum Parallelism
 property value based on the number of CPUs available on the nodes where mappings run.
