-----------------------------------
Summary: Support {INSERT,UPSERT}_IGNORE in the 'kudu table copy'
CLI tool
Key: KUDU-3468
URL: https://issues.apache.org/jira/browse/KUDU-3468
Project: Kudu
Issue Type: Improvement
Components: CLI
Reporter: Alexey Serbin
It would be great to make {{kudu table copy}} CLI tool supporting
{{INSERT_IGNORE}} and {{UPSERT_IGNORE}} operations. Having that is necessary
to make copying tables from one cluster to another re-entrant, i.e. make it
possible to restart the script/command (without preliminary resetting/cleaning
the destination table) if copying failed in the middle due to some transient
error.
Another approach might be starting a multi-row transaction in the destination
Kudu cluster, so in case of a failure all the inserted rows rolled back, but
that should be handled as a separate issue.
