>                 URL: https://issues.apache.org/jira/browse/KUDU-1688
>             Project: Kudu
>          Issue Type: Improvement
>          Components: impala, perf
>    Affects Versions: 1.0.0
>            Reporter: Todd Lipcon
>            Assignee: Alexey Serbin

>
> Currently Batcher::ProcessWriteResponse will log a VLOG(1) entry for every 
> row error it experiences. When using INSERT IGNORE in Impala, this can yield 
> thousands of logs per second and makes it extremely slow.
> We should consider bumping this to a higher vlog level, or pushing the 
> 'insert ignore' flag into the operations themselves (even before KUDU-1563 is 
> finished we could just drop the errors inside the client side)
