Subject [jira] Commented: (CASSANDRA-414) remove sstableLock
Date Fri, 04 Sep 2009 16:00:59 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12751507#action_12751507
] 

Jonathan Ellis commented on CASSANDRA-414:
------------------------------------------

rebased.

02
    remove sstableLock.  re-order a few ops so that we can never "lose" data temporarily --
always remove old sstable _after_ adding the new ones.  so at worst a few read ops will merge
data from an sstable that is obsolete -- this is ok and better than Stop The World locking

01
    combine addToList and storeLocation; rename to addSSTable
