MongoDB Driver v0.2

Alwyn_Bester · November 19, 2013, 1:38pm

It is recommended that you change to this version of the driver if you are using the driver in your MongoDB projects. This version fixes an issue with queries that return large result sets (2000+ documents). Previously the driver would crash when a query returned in the range of 2000+ documents.

This version of the driver was successfully tested with a result set that contained 641,337 documents, and processed these documents in 188 seconds (3,411 documents per second). I’m confident that the driver will now be able to handle more than a million documents in a single query. During testing the driver’s memory footprint also never went above 17MB, this while running in the IDE (I haven’t tested the compiled version of the driver yet).

Once again a big thanks to Patrick for his test app contributions and his help in finding bugs and thereby improving the driver.
