Amazon EC2 Cassandra Cluster with DataStax AMI

About:
,
,
,
,
,

This AMI does the following:

  • installs Cassandra 0.7.4 on a Ubuntu 10.10 image
  • configures emphemeral disks in raid0, if applicable (EBS is a bad fit for Cassandra
  • configures Cassandra to use the root volume for the commitlog and the ephemeral disks for data files
  • configures Cassandra to use the local interface for intra-cluster communication
  • configures all Cassandra nodes with the same seed for gossip discovery

Note the “EBS is a bad fit for Cassandra”. That’s what Adrian Cockcroft explains in Multi-tenancy and Cloud Storage Performance.
