Alexey Serbin commented on KUDU-3351:
-------------------------------------
Thank you for the patch, [~rizaon].
I see you marked this JIRA item as resolved. Are you planning to expose the
newly added stats in the Java client API in a separate patch in the scope of a
separate JIRA? The changelist 0ddcaaabc97c85a4715ae79ff5604feb9b342779
introduced the stats to the WriteRequestPB, filling them in at the server side,
and exposing that via the Kudu C++ client API, but Java client API doesn't
expose the stats as of now.
> Add insert error count metrics in WriteResponsePB
> -------------------------------------------------
>
> Key: KUDU-3351
> URL: https://issues.apache.org/jira/browse/KUDU-3351
> Project: Kudu
> Issue Type: Improvement
> Reporter: Riza Suminto
> Priority: Major
> Fix For: 1.17.0
>
>
> KUDU-1563 adds support for INSERT_IGNORE, UPDATE_IGNORE, and DELETE_IGNORE.
> However, it is currently lack of per-session metrics about how many rows get
> ignored vs modified.
> In regular INSERT operation, we depends on per_row_errors field in
> WriteResponsePB to count how many row operations are failed.
> [https://github.com/apache/kudu/blob/0cb2b7c/src/kudu/tserver/tserver.proto#L175-L183]
>
> But with INSERT_IGNORE, this field will be empty. We should add relevant
> metrics field to this WriteResponsePB.
