Here I attach some my think towards this.
> Support atomic append on a string field or increment of an int field

> Key: KUDU-3251
> URL: https://issues.apache.org/jira/browse/KUDU-3251
> Project: Kudu
> Issue Type: New Feature
> Reporter: wangningito
> Priority: Minor
>
> For some scenarios, the user may only want increase/decrease the for numeric
> field, or append a suffix to string field.
> Currently, it could be implemented with application.
> # load data with scan
> # apply increment/decrement in memory
> # send a increased/decreased value to server with updateRpc.
> Despite the poor performance, it also would make result error when multiple
> process/threads is doing ingestion.
> Introduce this may make some thing easier.
