Subject [jira] [Commented] (HBASE-18023) Log multi-* requests for more than threshold number of rows
Date Wed, 14 Jun 2017 04:27:00 GMT

stack commented on HBASE-18023:
-------------------------------

I added you as a contributor [~dharju] 

I like [~clayb] suggestion. I think adding some threshold -- 1k items in a mutation probably
merits a mention in the log (with perhaps a pointer to doc or issue on why many small batches
will go down better than a few massive ones.... If log becomes annoying operator can up the
threshold).

> Today, if a user happens to do something like a large multi-put, they can get through
request throttling (e.g. it is one request) but still crash a region server with a garbage
storm. We have seen regionservers hit this issue and it is silent and deadly. The RS will
report nothing more than a mysterious garbage collection and exit out.
> Ideally, we could report a large multi-* request before starting it, in case it happens
to be deadly. Knowing the client, user and how many rows are affected would be a good start
to tracking down painful users.
