David Alves updated CASSANDRA-3885:
-----------------------------------
Attachment: CASSANDRA-3885.patch
much simple and readable patch (imo).
- adds a column slice object (gets rid of the nasty unchecked cast warnings)
- gets rid of the isColumnNeeded method and diminishes the number of bb
comparisons
> Support multiple ranges in SliceQueryFilter

> This is logically a subtask of CASSANDRA-2710, but Jira doesn't allow
> sub-sub-tasks.
> We need to support multiple ranges in a SliceQueryFilter, and we want
> querying them to be efficient, i.e., one pass through the row to get all of
> the ranges, rather than one pass per range.
> Supercolumns are irrelevant since the goal is to replace them anyway. Ignore
> supercolumn-related code or rip it out, whichever is easier.
> This is ONLY dealing with the storage engine part, not the StorageProxy and
> Command intra-node messages or the Thrift or CQL client APIs. Thus, a unit
> test should be added to ColumnFamilyStoreTest to demonstrate that it works.
