Defect Number
Enhancement Number
Cause
Resolution
The driver is behaving as expected. 

The default for batchMechanism is multiRowInsert. While faster, this choice only returns a single row count. To get individual row counts, switch to batchMechanism=nativeBatch.

- Setting batchMechanism=multiRowInsert (Default) : Batch insert done (25): [25, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
- Setting batchMechanism=nativeBatch : Batch insert done (25): [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
