Summary: Support Kudu "ignore" operations
Key: IMPALA-10465
URL: https://issues.apache.org/jira/browse/IMPALA-10465
Project: IMPALA
Issue Type: Improvement
Reporter: Grant Henke
Kudu recently added support for INSERT_IGNORE, UPDATE_IGNORE, and DELETE_IGNORE
to handle cases where users want to ignore primary key errors in an efficient
way. Impala already does this today for it's INSERT behavior, however it does
so by ignoring the per-row errors from Kudu client side. This requires a large
error buffer (which may need to be expanded in rare cases) to log all of the
warning messages which users often do not care about and causes significant RPC
overhead.
Instead it would be good to add a property or special IGNORE keyword to
leverage the new ignore operations.
