Jonathan Ellis updated CASSANDRA-172:
-------------------------------------
Attachment: 172-addendum.patch
Here is an addendum to v3. Primarily it cleans up the memtable iterator and
getSliceFrom. It also merges Cursor functionally (basically, just getCurrent)
into ColumnIterator. What do you think?
I will look at the SF code more closely now.
> A improved and more general version of get_slice

> Today, get_slice has to scan through all columns in every memtable and
> sstable to get a slice of columns. This becomes inefficient when the number
> of columns in a row is large. We need a more efficient API.
