Jonathan Lawlor commented on PHOENIX-1763:
------------------------------------------
[~enis] Just an FYI, HBASE-13421 just went in on branch-1+ of HBASE to address
the increased object creations that resulted from NextState introduction in
HBASE-11544. The fix from HBASE-13421 introduces ScannerContext into the
RegionScanner/InternalScanner interfaces to encapsulate the scanner limits and
progress towards those limits. With the introduction of ScannerContext, it made
the most sense to move NextState into the ScannerContext and revert the return
type of RegionScanner/InternalScanner to a boolean that indicates whether or
not more rows exist (I apologize for this as you have already done work to
incorporate the NextState...). I made sure to make ScannerContext match the
visibility of RegionScanner and I would be happy to provide any help in regards
to any issues you run into when incorporating this change.
Again, I apologize for yet another change in the RegionScanner interface!
However, this latest change from HBASE-13421 will ensure that all limit logic
is nicely encapsulated inside ScannerContext and will also ensure that we do
not have a bunch of additional object creations inside the hot code paths.
Please let me know if I can help in any way or provide some additional context
behind the changes.

> HBase-1.1 is in the works. However, due to HBASE-11544 and possibly
> HBASE-12972 and more, we need some changes for supporting HBase-1.1 even
> after PHOENIX-1642.
> We can decide on a plan to support (or not) HBase-1.1 on which branches by
> the time it comes out. Let's use subtasks to keep progress for build support
> for 1.1.0-SNAPSHOT.
