Subject [jira] Updated: (CASSANDRA-375) Echo writes to bootstrapping nodes
Date Mon, 24 Aug 2009 19:46:59 GMT


Sandeep Tata updated CASSANDRA-375:

    Attachment: 375.patch

Here's what the patch does:

1. Switch bootstrapNodes in TokenMetadata to Map<Token,EndPoint> so RackUnawareStrategy
can use it.
2. Fix AbstractStrategy and RackUnawareStrategy to incorporate the bootstrapping nodes for
getHintedStorageEndPoints through StorageService.getNStorageEndPointMap (now used by insert
and insertBlocking after 383)
3. Add unit test fot RackUnawareStrategy to test if bootstrapping nodes are being returned

> Writes that arrive during bootstrap need to be sent to the r replicas as well as the
new node being bootstrapped. In the current code, only the existing replicas get the writes
that arrive during bootstrap.
