In addition, MarkLogic 5 features the ability to keep a "hot copy" of the database in another data center for quick failover in the event of a disaster, as well as a journal-archiving function that allows a database to be restored to a particular point in time.
The company is also rolling out a new version of its developer edition, with the chief change being that customers can now use it in production. It's limited to a single two-CPU node and 40GB of data.
The company is small compared to database giant Oracle, with $50 million in revenue through the end of last year, but is growing quickly, according to Bill Veiga, vice president of solutions marketing.
It has 275 distinct customers and more than 500 implementations, Veiga added.
