Matt Corgan commented on HBASE-7897:
------------------------------------
{quote}BTW what is the other JIRA where the internals are going to be
discussed?{quote}I can't think of a specific jira - maybe one should be
created. Related issues include HBASE-6222, HBASE-7448, and HBASE-7662.
{quote}So Matt you suggest that i give an uploaded patch with the methods added
to Cell alone and remove the CellUtil.iterators for now?{quote}I've not been
working on this lately and don't mean to have too strong of a recommendation,
but if you agree the Cell interface should only focus on allocating a range of
bytes for the tags, then yes, I'd say we could have a separate issue/discussion
for the format of the tags bytes. I'm concerned that the logic behind the tags
is too complex to be handled at the Cell level. HBase already needs
performance improvements with regards to iterating cells, and parsing and
interpreting tags contents at the cell iteration level would be too expensive.
At the lower levels they should be as opaque as the contents of the value
byte[]. Others may disagree for sure - it's an important conversation.
