This is indeed a known issue in Kudu, and one of several reasons why Kudu
performs suboptimally for UPDATE-heavy workloads.

> Hi guys, I met a problem about the keys locks that almost impacts the service
> normal writing.
> As we all know, a transaction which get all row_key locks will go on next
> step in kudu. Everything looks good, if keys are not concurrent updated. But
> when keys are updated by more than one client at the same time, locks are
> acquired to wait much time. The cases are often in my product environment.
> Does anybody meet the problem? Has any good ideal for this?
> Thanks.
