Hollow, world! Netflix premieres Java in-memory database toolkit

The streaming media service on Monday released an open-source project called Hollow that dispenses with what it characterizes as the conventional wisdom about distributing datasets of a certain size over a network.

Koszewnik claims that Hollow has helped Netflix reduce server startup times and heap footprints even as it deals with more and more metadata. He also said it has helped the company realize productivity gains associated with disseminating its data catalog.
