Aleksey Yeschenko commented on CASSANDRA-6662:
----------------------------------------------
Now that I think of it, reconcileTail() path is kinda useless, and only adds
extra complexity. Doesn't make it more efficient - we still have to do the same
number of operations as in the regular path.
> Sort/reconcile cells in ArrayBackedSortedColumns only when an accessor is
> called

> Project: Cassandra
> Issue Type: Improvement
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Fix For: 2.1
>
>
> To avoid poor performance with huge numbers of cells added out of order
> (which should be rare, but *can* happen with certain batch scenarios) we
> should make ABSC only sort/reconcile its cells when an actual accessor is
> actually called, delaying sorting until the very end.
