Stu Hood commented on CASSANDRA-1189:
-------------------------------------
If streaming sessions/files were given unique ids, it would be helpful for
repairs as well.
AntiEntropyService.RepairSession in trunk and 0.6 only has a local view, so it
can't know when other nodes have finished streaming data for repairs: it only
blocks until streaming has started. If streaming sessions had unique ids, the
destination node could block for notification that a particular stream id had
finished before indicating that the repair was finished.

> Key: CASSANDRA-1189
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1189
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.7
> Reporter: Gary Dusbabek
> Assignee: Gary Dusbabek
> Priority: Critical
> Fix For: 0.7
>
>
> 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).
