I’m from RDB-crowd. For a long time as DBA I was working with OLTP/OLAP environments using MS Sql, Oracle, MySQL systems. Recently I tried to use nosql to create proof of concept for one of my projects which faces typical database issues – combining OLTP with OLAP (at least basics of it).
Tested MongoDB and RavenDB. Since I’m using .NET stack RavenDB seemed ideal to me. Speed of inserts is fantastic. But hey. It’s no surprise if you understand you’re just writing into flat file. Unfortunately immediately after that came disappointment. Idea of index running on background is fine while index is capable of doing what I need. It’s not the case here. If you need at least some basic analytics (group by, count(), sum()) either forget about nosql solution or be prepared to develop extra layer/ETL for pushing data into some other DB-warehouse engine. So far I was not able to find one working example proving I’m wrong. And I would be glad to to be wrong. Because the major characteristics of nosql – scalability and super fast data inserts are very sweet baits for me.
