When the MDM Hub runs a batch job, the

MDM Hub

divides the records queued for batch processing into blocks that the

MDM Hub

can process in parallel. You can configure the number of threads to use for each of the batch jobs in the

cmxserver.properties

file.

When the

MDM Hub

runs a load job on a parent base object, the

MDM Hub

applies a batch lock on the corresponding child base object. A batch lock on a child base object prevents another parent from running a load or merge job in parallel. The

MDM Hub

applies a batch lock on the child base object if the child has a unique key relationship with the parent base object.
