getCommitSizeMultiplier()
publicfloatgetCommitSizeMultiplier()
Returns the multiplier that will be applied to the calculated commit size to ensure that a
commit request in a non-atomic COPY operation does not exceed the fixed commit size limit of
Cloud Spanner.
Returns whether COPY operations should use upsert instead of insert.
COPY will INSERT records by default. This is consistent with how COPY on PostgreSQL works.
This option allows PGAdapter to use InsertOrUpdate instead. This can be slightly more efficient
for bulk uploading, and it makes it easier to retry a failed non-atomic batch that might have
already uploaded some but not all data.
