Facebook Query Language (FQL) is a query language that allows querying Facebook user data by using a SQL-style interface, [1] avoiding the need to use the Facebook Platform Graph API. [2] Data returned from an FQL query is in JSON format by default.
In a presentation headed by Facebook CEO Mark Zuckerberg, it was announced that the Graph Search algorithm finds information from within a user's network of friends. Microsoft's Bing search engine provided additional results. [2] In July it was made available to all users using the U.S. English version of Facebook. [3]
Facebook Connect, [25] also called Log in with Facebook, like OpenID, is a set of authentication APIs from Facebook that developers can use to help their users connect and share with such users' Facebook friends (on and off Facebook) and increase engagement for their website or application. When so used, Facebook members can log on to third ...
GraphQL supports reading, writing (mutating), and subscribing to changes to data (realtime updates – commonly implemented using WebSockets). [8] A GraphQL service is created by defining types with fields, then providing functions to resolve the data for each field. The types and fields make up what is known as the schema definition.
The news feed is the primary system through which users are exposed to content posted on the network. Using a secret method (initially known as EdgeRank), Facebook selects a handful of updates to actually show users every time they visit their feed, out of an average of 1500 updates they can potentially receive.
Data values can also be processed by functions, including aggregation functions, leading to the projection of computed values which render the information held in the projected graph in various ways. Following the lead of G-CORE and Morpheus, GQL aims to project the sub-graphs defined by matching patterns (and graphs then computed over those ...
ProPublica explicitly referenced the existence of Facebook's .onion site when they started their own onion service. [5] The site also makes it easier for Facebook to differentiate between accounts that have been caught up in a botnet and those that legitimately access Facebook through Tor. [6]
Scribe spools data to disk on any node to handle intermittent connectivity node failure, but doesn't sync a log file for every message. This creates a possibility of a small amount of data loss in the event of a crash or catastrophic hardware failure. However, this degree of reliability is often suitable for most Facebook use cases.
