I have a 3-node cluster in production and a single-node development cluster. I
tested snapshotting a column family from the 3-node production cluster,
grouping the files together, and restoring onto my single node development
system. That worked fine. Can I go the other direction? It's not
supposed to be the only one -
shrug.

Just had something odd happen - my keyspace disappeared. I'm curious if anyone
has seen the same or may have an explanation.
I am using Titan 0.2.0 and Cassandra 1.1.6. I ran my application which creates
a graph and progressively builds it for a couple of hours. But before
completing, Cassa
"-Dcassandra.replace_token="
when bringing up the new node, this problem wasn't exhibited. Everything
worked smoothly.

I witnessed the same behavior as reported by Edward and James.
Removing the host from its own seed list does not solve the problem. Removing
it from config of all nodes and restarting each, then restarting the failed
node worked.

Unless I see the error again, I'm guessing there was some data leftover between
trials.

We have some production Solaris boxes so I can't use SnappyCompressor (no
library included for Solaris), so I set it to JavaDeflate. I've also noticed
higher load issues with 1.1.0 versus 1.0.6: could this be JavaDeflate, or is
that what the old default was? Anyway, I thought I would try no c

Thanks for verifying that.

I upgraded to 1.0.6 to 1.1.0, and I noticed the effective ownership report
changed.
I have a 3-node cluster, with evenly divided tokens and RF=2. The node tool
report on 1.0.6 was:
33.33% 0
33.33% 56713727820156410577229101238628035243
33.33%
I have a column family for my main data, and I have been using an additional
column family to store indexes to the data: row per index style.
I now want to be able to update a set of indexes by the field being indexed on.
To access that set, I can maintain meta indexes for each field, or I can

I am doing some experimenting with indexing. My data CF has about 25000 rows
around 1KB each. I set up a special column of boolean value to use as the
secondary index. I also created my own index in a separate CF where each index
is one row and the column names are the data keys.
