Fabien Rousseau commented on CASSANDRA-6119:
--------------------------------------------
After having reviewed your patch, it has definitely a better approach
minimising code change and better readability
So I'm +1 for your patch
> IndexedSliceReader can skip columns when fetching multiple contiguous slices

> This was observed using SliceQueryFilter with multiple slices.
> Let's have a row "a" having the following column list : "colA", "colB",
> "colC", "colD"
> Then select 2 ranges : ["colA", "colB"], ["colC", "colD"]
> Expected result is the four columns
> But only 3 are returned ("colA", "colB", "colD")
> To reproduce the above scenario in the unit tests, you can modify the test
> "ColumnFamilyStoreTest.testMultiRangeIndexed" by replacing the original line :
> String[] letters = new String[] { "a", "b", "c", "d", "e", "f", "g",
> "h", "i" };
> by this one ("f" letter has been removed) :
> String[] letters = new String[] { "a", "b", "c", "d", "e", "g", "h",
> "i" };
> Anyway, a patch is attached which adds more unit tests, and modifies
> IndexedSliceReader.IndexedBlockFetcher &
> IndexedSliceReader.SimpleBlockFetcher
