[jira] [Created] (CASSANDRA-7793) Utilize BATCH statements in COPY FROM

Mikhail Stepura created CASSANDRA-7793:
------------------------------------------

             Summary: Utilize BATCH statements in COPY FROM
                 Key: CASSANDRA-7793
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7793
             Project: Cassandra
          Issue Type: Improvement
          Components: Tools
            Reporter: Mikhail Stepura
             Fix For: 2.1.1


If we assume that a significant subset of COPY FROM csv's are going to be results of COPY TO command, then rows will be grouped by the partition key. In that case we'd win from batching (until another partition key is met, and constrained by some limit of rows per batch, we don't want huge batches)
