What is the difference between `BatchRecordArrayListener` and `RecordArrayListener`? #285

Judging by the documentation, they serve similar purpose, the only difference being slightly different API. The question is, does BatchRecordArrayListener has any performance improvements compared to RecordArrayListener?

BrianNichols commented 1 year ago

BatchRecordArrayListener responds with BatchRecord[] which includes a resultCode for each key. RecordArrayListener responds with Record[] which does not include a resultCode for each key. If an error occurred for a key, the corresponding record will be null. Performance differences are negligible.

RecordArrayListener was used in the original batch read only implementation and still exists in that form for legacy reasons.
