I'm looking at use Cassandra to store and index logs, particular those based around security events source from syslog and custom agents.<p>Anyone gone down this path and found Cassandra to be the wrong tool for the job? It's replication is really the attractive item for me.
I haven't tried it (EDIT: it = cassandra), but what's wrong with Logstash + ElasticSearch? You get a lot out of the box with Logstash, and you could always push the community to build a Cassandra output plugin (or build it yourself) if you have serious reasons for Cassandra vs. ElasticSearch. Though Kibana is a great interface for log searching and is designed to interface with ES.
Thanks. I had not considered ElasticSearch but already ruled out Logstash for various reasons. ElasticSearch looks like the perfect starting point, gives me 90% of what I need.
