Facebook released new versions of its flagship applications for iOS and Android Wednesday, with the iOS app adding some unannounced tweaks to its recently introduced opt-in Nearby Friends feature, while the major addition to the Android app was the ability for users to like posts, photos, and pages while they are offline.
The average Facebook user has never heard of HydraBase, but the souped-up version of Apache HBase, an open-source distributed key value data store running on top of HDFS, was instrumental in the social network’s move in 2010 to revamp its messages inbox to include Facebook messages, SMS, chat, and email. Since then, the technology has been use to launch other features, as well.
With Facebook’s first-quarter earnings call set for Wednesday after the close of trading, digital marketing agency 3Q Digital offered a preview of the social network’s potential advertising results by sharing data from its clients across a variety of advertiser objectives and verticals.
Facebook is officially introducing a feature it has toyed with in simpler form in the past, as the social network announced the launch of Nearby Friends in a Newsroom post, saying that it will be available to U.S. Android and iPhone users “in the coming weeks.”
