Subject [jira] Created: (CASSANDRA-847) Make the reading half of compactions memory-efficient
Date Thu, 04 Mar 2010 04:23:27 GMT
Make the reading half of compactions memory-efficient
-----------------------------------------------------

                 Key: CASSANDRA-847
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-847
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Stu Hood
            Priority: Critical
             Fix For: 0.7
         Attachments: 0001-Add-structures-that-were-important-to-the-SSTableSca.patch, 0002-Implement-most-of-the-new-SSTableScanner-interface.patch,
0003-Rename-RowIndexedReader-specific-test.patch

This issue is the next on the road to finally fixing CASSANDRA-16. To make compactions memory
efficient, we have to be able to perform the compaction process on the smallest possible chunks
that might intersect and contend one-another, meaning that we need a better abstraction for
reading from SSTables.
