Stefania created CASSANDRA-11474:
------------------------------------
Summary: cqlsh: COPY FROM should use regular inserts for single
statement batches
Key: CASSANDRA-11474
URL: https://issues.apache.org/jira/browse/CASSANDRA-11474
Project: Cassandra
Issue Type: Bug
Components: Tools
Reporter: Stefania
Assignee: Stefania
Fix For: 2.2.x, 3.0.x, 3.x
I haven't reproduced it with a test yet but, from code inspection, if CQL rows
are larger than {{batch_size_fail_threshold_in_kb}} and this parameter cannot
be changed, then data import will fail.
Users can control the batch size by setting MAXBATCHSIZE.
If a batch contains a single statement, there is no need to use a batch and we
should use normal inserts instead or, alternatively, we should skip the batch
size check for unlogged batches with only one statement.
