Elastic Search is known to drop your data in some occasions. I think it's fair to advise against using it as your source of truth (or anything built on top of it like Crate).

the elastic team is working hard in fixing the issues discovered by aphyr (jepsen test). you can find the current status here: http://www.elastic.co/guide/en/elasticsearch/resiliency/curr... - we're doing our best to support them. (btw. here's what aphyr thinks about that document: https://twitter.com/aphyr/status/525712547911974913)

Yes, and while there are still cases (see the link @jodok supplied below) a ton of work was done in ES v1.4.x (which Crate uses) and even more issues were closed in ES v1.5 which we're working on supporting.
With the amount of attention and support this has received from both Crate and ES, coupled with the amount of progress that's been made against these issues, I don't think it's a fair to advise against using either as a source of truth.

The Lucene team has been promising an end to corruption since the 2.9 days and before (~10 years). If you believe them that the problems are all fixed, and you need to be serious about it, I'd wait more than a month before declaring the problem solved.
That said, they are checksumming a hell of a lot more than before, so there's a chance.
