Hudson commented on CASSANDRA-332:
----------------------------------
Integrated in Cassandra #161 (See
[http://hudson.zones.apache.org/hudson/job/Cassandra/161/])
final cleanup of SSTableSliceIterator, now with less unnecessary copying of
Columns around
patch by jbellis; reviewed by Jun Rao for
avoid copying variables to ColumnGroupReader that it can get from the parent
class. rename underscored variables.
patch by jbellis; reviewed by Jun Rao for
move comparator out of IndexInfo
patch by jbellis; reviewed by Jun Rao for
always write at least one index (with first and last column of the range) for
the columns in row. this vastly simplifies column reading code and makes
indexing bugs much more obvious (since there is only one read path each for
names / slices now).
patch by jbellis; reviewed by Jun Rao for
don't serialize unused column count into column index. remove DataInput/Output
round-tripping from ColumnGroupReader
patch by jbellis; reviewed by Jun Rao for
add test for multi-block reversal.
