Subject [jira] [Updated] (CASSANDRA-5219) get_indexed_keys
Date Sat, 23 Mar 2013 22:53:15 GMT


Jonathan Ellis updated CASSANDRA-5219:

    Priority: Minor  (was: Major)
> get_indexed_keys
> ----------------
>                 Key: CASSANDRA-5219
>                 URL:
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Srdjan Mitrovic
>            Priority: Minor
> We would like to get the list of keys for some indexed value by using only one disk seek
per node.
> Unfortunately get_indexed_slices would also read CF where keys can be in many different
places so it would take many disk seeks just to get the list of keys.
> Something like get_indexed_keys(keyRange) would be very beneficial to us.
> Much better idea is to use existing 
> list<KeySlice> get_range_slices(ColumnParent column_parent, SlicePredicate predicate,
KeyRange range, ConsistencyLevel consistency_level) without breaking any compatibility. 
> If SlicePredicate has empty list of columns and KeyRange has an IndexExpression then
only index should be fetched to return the desired keys without touching indexed CF.
