Classified advertising service Craigslist found this feature handy, for instance, when adding a column to housing listings to say whether pets are allowed in an apartment. Such a feature would take months to add to a standard relational database.
"It's a simple thing. It probably took a developer 15 minutes to write that code. But it would take three months to comb through its terabytes of data to push out the columns, row by row, to have that one binary value, yes or no," Asay said.
At the conference, Facebook subsidiary Parse, a mobile analytics firm acquired by Facebook in April, will also unveil the open-source release of a number of tools related to MongoDB.
Parse has opened sourced Flashback, which developers can use to test and tune performance of their MongoDB databases, and Dvara, which can extend the number of active servers a MongoDB database can use.
Open-source data analysis vendor Pentaho also announced that the new version of its flagship product, Pentaho 5.1, comes with the capability to run code-free analytics directly on MongoDB data stores.
