It's "CQL query must be bytes, not unicode" error when attempting COPY TO and COPY FROM in CQL3 mode. Nothing else seems to be affected (DESCRIBE * command work fine and all field types are properly deserialized/formatted in both CQL2 and CQL3 mode). > improve cqlsh COPY FROM performance > ----------------------------------- > > Key: CASSANDRA-4921 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4921 > Project: Cassandra > Issue Type: Improvement > Components: Tools > Affects Versions: 1.1.2 > Reporter: Jonathan Ellis > Assignee: Aleksey Yeschenko > Priority: Minor > Fix For: 1.1.7 > > > Profiling shows that prepare_inline takes the vast majority of cqlsh COPY > FROM time, particularly on csv rows with many columns. -- This message is automatically generated by JIRA.
