Alexey Serbin commented on KUDU-3351:
-------------------------------------
>From what I can see, the scope of this JIRA seems to be something server-side
>only, but since your patch also added support for the Kudu C++ client side, I
>was curios whether you were planning to add similar functionality to the Kudu
>Java client as well. I think creating a separate one for the Java client-side
>work might be an option:
>[KUDU-3365|https://issues.apache.org/jira/browse/KUDU-3365]. Feel free to
>assign it to yourself if you are planning to work on that. Thank you!
> 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.
