--------------------------------------
Summary: OffheapKeyValue#heapSize() implementation is wrong
Key: HBASE-17647
URL: https://issues.apache.org/jira/browse/HBASE-17647
Project: HBase
Issue Type: Sub-task
Reporter: Anoop Sam John
Assignee: Anoop Sam John
Fix For: 2.0.0
We consider the key and data lengths also even though the data is actually in
off heap area. We should correct it.
The impact will be at ScannerContext limit tracking where we use heapSize of
cells to account the result size. So my proposal is to consider the cells
length and heap size in Limit tracking and accounting. We have a maxResultSize
which defaults to 2MB. When the sum of all cell's data size reaches
'maxResultSize' OR the sum of all cell's heap size reaches 'maxResultSize' ,
we need to send back the RPC response
