mongodb – Another competitor for the schemaless database space, a quick look
Posted by: admin in computingMongoDB, another competitor for the schemaless database space. This is from 10gen who provides a hosted version of the database. DB engine licensed under the AGPL – so no webservice loopholes. Has some pretty interesting performance metrics.There are drivers for Python, C+, PHP, Java, Ruby and Javascript (using the V8 engine).
Stores data in BSON -binary JSON – that besides being a binary serialisation of JSON also has extension for types such dates and binary data.
Supports db replication. Pretty funky auto sharding planned, although not completed. No transactions. No server side joins so you either embed your objects together or you create references between them . Supports advanced querying capabilities as well as server side excution of code for searching and processing on the client.
Looks real promising.
