[jira] [Created] (CASSANDRA-5555) Allow sstableloader to handle a larger number of files

Tyler Hobbs created CASSANDRA-5555:
--------------------------------------

             Summary: Allow sstableloader to handle a larger number of files
                 Key: CASSANDRA-5555
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5555
             Project: Cassandra
          Issue Type: Improvement
          Components: Tools
            Reporter: Tyler Hobbs
            Assignee: Tyler Hobbs


With the default heap size, sstableloader will OOM when there are roughly 25k files in the directory to load.  It's easy to reach this number of files in a single LCS column family.

By avoiding creating all SSTableReaders up front in SSTableLoader, we should be able to increase the number of files that sstableloader can handle considerably.
