ClearVoice simplifies their scalable backend with CrateDB
As ClearVoice was preparing for its launch, it was looking for a back-end database for its application. It had used MySQL as its development database, but since the amount of data being stored was about to grow immensely, ClearVoice planned to de-normalize its data schema and store it in a distributed fashion, using MongoDB and Elasticsearch, Solr or another Lucene-based solution.

Jeff also mentions that the ability to use SQL as CrateDB’s interface language was an added benefit since SQL reduces the learning curve when developers need to interface with distributed systems and was much simpler than writing complex queries in JSON. "The fact that CrateDB uses SQL lowers the barriers to entry when using distributed search. And on top of that, with CrateDB you can replace MongoDB and Elasticsearch with one scalable package."
Today, CrateDB holds 20 million records and is expected to grow into billions in the near future. Its primary function is the search index powering ClearVoice.
