Facebook is using HipHopVM, which is a JIT for PHP. HipHop is no longer a PHP -> C++ compiler.

Didn't know they switched to HBase, it's still Java though.

"Facebook uses hphpi (and now hhvm) for day-to-day software development, but uses the HipHop compiler (hphpc) to create optimized binaries that serve the Facebook website. hphpc is in essence a traditional static compiler that converts PHP→AST→C++→x64."

That note is from 2011.

According to wikipedia: http://en.wikipedia.org/wiki/HipHop_for_PHP

"in Q1 2013, the production version of facebook.com started running on HHVM, replacing HPHPc."
