Increasing the size limits implications

[Bobbie Haynes]

Hi,
      I'm inserting into cassandra in batches(With each containing single
PK ).But my batch is failing and throwing exceptions.
I want to know if we increase batch_size_warn_threshold_in_kb to 200KB
and batch_size_fail_threshold_in_kb
to 300KB. What could be potential issues i could be facing

Thanks,
Bobbie
