Multi-threaded Batch Job Example

Multi-threaded Batch Job Example

The MDM Hub uses the block size you configure to determine the number of records that it must process in each block. The MDM Hub divides the total number of records to process by the block size.
Consider a scenario where the number of records to be processed in a batch is 3000, the number of threads that you configured is 4, and the block size is 250. The MDM Hub divides the total number of records by the block size, which results in 12 blocks of 250 records each. The MDM Hub then assigns a block to each thread for processing. When a thread completes processing a block, the next block in the queue is assigned to it. The MDM Hub continues assigning blocks to threads that free up, until all blocks are processed.
The records queued for batch processing divided by block size and assigned to threads for processing.
