Hello again, last day's I started several tests with Cassandra and learned quite some facts.
However, of course, there are still enough things I need to understand. One thing is, how the data replication works. For my Testing: 1. I set the replication Factor to 3, started with 1 active node (the seed) and I inserted some test key's. 2. I started 2 more nodes, which joined the cluster. 3. I waited for the data to replicate, which didn't happen. 4. I inserted more key's, and it looked like they were distributed to all three nodes. So here is my question: How can I ensure that every key exists at least on three nodes? So, when I start with one node and later join 2 more - the data will be distributed. Shouldn't this happen automatically? Am I just not patient enough? How is this handled in productive environments? For instance, one node has a hardware failure, so it will be exchanged with a new blank one. How does that one get it's data back? I searched the mailinglist, the only answer I found was to copy the data manually, is this true? I'm currently using Cassandra 0.6.4 in our testing environment. I chose the RackUnawareStrategy Stefan
