We're working on an organisation with quita a few batch processes. Monitoring some of the batch operations in testing I noticed that under the Operation column, there are both SerialBatchApexRangeChunkHandler and Batch Apex.

A batch process that I'm working on runs as Batch Apex in a full sandbox, but runs as SerialBatchApexRangeChunkHandler in the production organisation.

batch apex vs SerialBatchApexRangeChunkHandler

I fail to find (may be depended on my search capabilities) any explanation to the difference in the documentation. Can any of you feed my hunger for knowledge ?


If you process 1000 records these will be processed in 5 chunks of 200 records. For each chunck you will see a SerialBatchApexRangeChunkHandler (corresponds to the execute method in the batch).

    That is also the case for the rows showing Batch Apex. What is the difference and why does the batch process giving SerialBatchApex... in production Batch Apex in sandbox ? – Samuel De Rycke Sep 10 '12 at 9:26
