Subject Long Startup Times
Date Sun, 15 Apr 2012 17:13:56 GMT

I have 2 column families with approx 50 GB of compressed data (~150GB
uncompressed).  The data resides in a keyspace replicated 2-way, hosted by
a 2-node Cassandra cluster (v1.0.8), both with 74GB RAM and 16 cores.
 Key caches are set to 1.0.

I'm noticing that it can take upwards of 15+ minutes for the node to start
up (i.e. before it becomes responsive to thrift clients).  During this
time, the logs suggest the system is blocked opening the data files.

Is this expected behaviour?  Are there any best practices for reducing node
startup time?

Thanks in advance!
