Re: Cassandra vs Elasticsearch.

I've come up with a driver so that Elasticsearch can store its index data in Cassandra. I'm not sure how well it performs, as I haven't really put it through any big data sets. But you then get the advantage of data durability in Cassandra and the search capability of Elasticsearch. It's very expe

cleanup failure; FileNotFoundException deleting (wrong?) db file
