Reviews
MongoDB provides high availability with replica sets.[9] A replica set consists of two or more copies of the data. Each replica set member may act in the role of primary or secondary replica at any time. All writes and reads are done on the primary replica by default. Secondary replicas maintain a copy of the data of the primary using built-in replication. When a primary replica fails, the replica set automatically conducts an election process to determine which secondary should become the primary. Secondaries can optionally serve read operations, but that data is only eventually consistent by default.
An excellent software, one of the things that I like most about mongo is the enalce between database, a fairly simple aspect is to make the correlations, it does not use a very technical language, it is quite light and it is possible to implement it in medium equipment. performance.
Great DB for startups. I was able to implement a polyglot solution combining MongoDB and Neo4j, a graphdb. The architecture has not fundamentally changed since (Aug 2013) and we now serve over 1 million users a month. And we have a lot spare room to grow with, with no major db changes. Our solution has scaled period, could not have done it with a relational db.
