To improve batch loading speed, it is critical to reduce the amount of database round trips for each operation.
To achieve this, it is required to prevent auto generated columns when
idGenMode == IDGenMode.USE_EXISTING && idGenMode.isSkipResolveReferences()is used and all identifying column values are already known.In this PR the handling of auto generated columns was optimized in
InsertRowand also support for batching was introduced inInsertRowManager.
