Improve performance of cached row slices
----------------------------------------
Key: CASSANDRA-1267
URL: https://issues.apache.org/jira/browse/CASSANDRA-1267
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: T Jake Luciani
Priority: Minor
Fix For: 0.7
In Lucandra, I have a use case to pull all columns for a given row.
I've noticed that for rows with large numbers of columns this takes much longer
than I would think since row caching is enabled.
After looking into this I see that the cached row is rebuilt and pruned even
though I want all columns.
This patch skips this use case and in my case has improved performance
significantly.
