Stu Hood commented on CASSANDRA-2904: ------------------------------------- CASSANDRA-2319 implements something like this. > get_range_slices with no columns could be made faster by scanning the index > file > -------------------------------------------------------------------------------- > > Key: CASSANDRA-2904 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2904 > Project: Cassandra > Issue Type: Improvement > Components: Core > Affects Versions: 0.7.6 > Reporter: Jean-Francois Im > > When scanning a column family using get_range_slices() and a predicate that > contains no columns, the scan operates on the actual data, not the index file. > Our use case for this is that we have a column family that has relatively > wide rows(varying from 10kb to over 100kb of data per row) and we need to do > iterate through all the keys to figure out which rows we are interested in; > obviously, going through the index file than the data is faster in this > case(in the order of minutes versus hours). -- This message is automatically generated by JIRA.
