Subject [jira] Updated: (CASSANDRA-1189) Refactor streaming
Date Tue, 03 Aug 2010 21:37:18 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-1189?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nirmal Ranganathan updated CASSANDRA-1189:
------------------------------------------

    Attachment: 0002-Test-cases-for-Streaming-Messages.patch
                0003-1189-Fixes-v1.patch

Updated most of the suggested changes, I wasn't able to simplify StreamHeader, StreamContext
and PendingFile. 

I've run various test for Request & Transfer and seems good, however there was one case
when I got an error flushing the SSTable, looks like compaction happened before the file transfer
could be completed, on a request. I'm trying to reproduce that, in the meantime here's the
patch with updates.

> The current architecture is buggy because it makes the assumption that only one stream
can be in process between two nodes at a given time, and stream send order never changes.
 Because of this, the ACK process gets fouled up when other services wish to stream files.
> The process is somewhat contorted too (request, initiate, initiate done, send).
