It is often advocated as a datastore for logging data... which means (in that case) it's usually the primary datastore but perhaps not mission-critical.

It's a great index for log data.

Spew your log data into a standard syslog server, while also pumping it into Logstash.

Using Elasticsearch as your canonical log storage would be ridiculous.

Once you start relying on it to understand the state of whatever it's logging, it's mission-critical.
