> Unify tracking of block IO across all read request types
> --------------------------------------------------------
>
> Key: HBASE-27570
> URL: https://issues.apache.org/jira/browse/HBASE-27570
> Project: HBase
> Issue Type: Improvement
> Reporter: Bryan Beaudreault
> Assignee: Bryan Beaudreault
> Priority: Major
> Fix For: 2.6.0, 3.0.0-alpha-4
>
>
> Various requests in RSRpcServices use
> [addSize|https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/RSRpcServices.java#L1303-L1335]
> in an attempt to estimate block IO of the request by pulling the capacity of
> the underlying cell buffer when that buffer changes. This is just an estimate
> and can be inaccurate in certain circumstances, such as when the ordering of
> gets in a multiget causes the same buffer to be counted twice.
> As of HBASE-27558, we now have a hook in StoreScanner for tracking block IO
> via HFileReaderImpl.reportBlockSize method call. We use this for getting
> block IO into ScannerContext for tracking limits. We can add a call to
> RpcCall.incrementResponseBlockSize here so that we can get an accurate
> accounting of block IO for all request types.
