Until then, you are left w/ some sort of hack on KV.
Yes.
If all was Cell on the read/write path, I'd imagine
it'd be easy enough getting your tags in the mix.
Am checking on this also. May take some time till i finalise on the
changes.
Will discuss with Andy offline and get back on some

Good question. If the read/write path currently does not support
On HBASE-7544 I added encryption to HFile starting with the encoder and
decoder contexts and working outward, so I can attest it is possible to add
features that wrap *around* KV serialization without changing the KV
serialization itself. On trunk the block encoder stuff has been at least
fyi Ram - i started adding the Cell interface to the read path of the delta
encoders in HBASE-7323 https://issues.apache.org/jira/browse/HBASE-7323.
It's one possible place to start working on it.

A related question. Can you clarify the distinction between a Cell and a
KeyValue as pertains to the timestamp? That is, which of these two concepts
carries the timestamp as a component of its coordinates? Does a Cell
contain multiple KeyValue versions or does a KeyValue contain multiple Cell
Just adding to what Matt said,
Cell and KeyValue are the same.
Just that in cell you have individual byte arrays carrying the Row, family,
qualifier, Type and timestamp.
So it is basically saving us from the internal size it occupies. Also it
helps us to use the same interface between the RPC

Could someone clarify on this pls?

Thanks for your reply Stack.
I think so. hfile APIs are about KVs. Should be about Cell I'd think.
Yes. This is what i too think.
If you need the above, you are no doing Cell right I'd argue. The very
idea of Cell is a disconnect between how it is stored and Cell use.
Yes Stack. I

The current block encoder which encodes the kvs into hfile blocks will be
enhanced may be BlockEncode2 which will deal with Cell
