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).
