-----------------------------------
Fix Version/s: Impala 4.2.0
Resolution: Fixed
> Improve Kudu DML error logging in Impala
> ----------------------------------------
>
> Key: IMPALA-10465
> URL: https://issues.apache.org/jira/browse/IMPALA-10465
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Grant Henke
> Assignee: Riza Suminto
> Priority: Major
> Fix For: Impala 4.2.0
>
>
> 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.
