[jira] [Commented] (CASSANDRA-5555) Allow sstableloader to handle a
larger number of files
[ https://issues.apache.org/jira/browse/CASSANDRA-5555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13676075#comment-13676075 ]
Tyler Hobbs commented on CASSANDRA-5555:
----------------------------------------
[~jbellis] did you still want to increase the default heap size? Just want to make sure you didn't forget to increase it if you intended to.
FYI, we'll likely do a stress test to see what the new limit is with these changes.

> 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.
