> Limit max result size of individual Gets
> ----------------------------------------
>
> Key: HBASE-26122
> URL: https://issues.apache.org/jira/browse/HBASE-26122
> Project: HBase
> Issue Type: New Feature
> Components: Client, regionserver
> Reporter: Bryan Beaudreault
> Assignee: Bryan Beaudreault
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-2
>
>
> Scans have the ability to have a configured max result size, which causes
> them to return a partial result once the limit has been reached. MultiGets
> also can throw MultiActionResultTooLarge if the response size is over a
> configured quota. Neither of these really accounts for a single Get of a
> too-large row. Such too-large Gets can cause substantial GC pressure or worse
> if sent at volume.
> Currently one can work around this by converting their Get to a single row
> Scan, but this requires a developer to proactively know about and prepare for
> the issue by using a Scan upfront or wait for the RegionServer to choke on a
> large request and only then rewrite the Get for future requests.
> We should implement the same response size limits for for Get as for Scan,
> whereby the server returns a partial result to the client for handling.
