Jonathan Hsieh commented on HBASE-9383:
---------------------------------------
I punted on this because I wasn't sure how far the encoded cells are percolated
through the RS. I assume the heap size of the KV is used for memstore/buffer
cache accounting. are prefixtree cells present in the memstore? is encoded
data present in the block cache or are the expanded?
for prefixtree heapsize, it would make sense to count the pointers, and
separately count the shared prefixpool.

> Key: HBASE-9383
> URL: https://issues.apache.org/jira/browse/HBASE-9383
> Project: HBase
> Issue Type: Sub-task
> Affects Versions: 0.96.0
> Reporter: Jonathan Hsieh
>
> From the review of HBASE-9359.
> bq. Stack: Cell should implement HeapSize? That sounds right.
> bq. Ram: +1 for Cell extending HeapSize.
> bq. Jon: I'll look into Cell extending HeapSize as a follow on. It doesn't
> interfere with the signature and if a older 0.96 client talks to a 0.96.1 rs
> that has the change, it won't matter.
