Subject [jira] Commented: (CASSANDRA-674) New SSTable Format
Date Tue, 01 Feb 2011 09:29:31 GMT


Stu Hood commented on CASSANDRA-674:

One of the key blockers is implementing rebuilding of SSTables post-streaming. Based on an
IRC conversation yesterday, the smoothest way to support streaming of older SSTable versions
was to ABC and subclass what is now the SSTableWrite.Builder object: I'll probably try to
do this in a separate ticket.
