Reliably delivering a customizable subset of hundreds of millions of daily Tweets to hundreds of customers with thousands of end-users is no small feat, especially when that has to be done in realtime without missing a Tweet. Twitter’s PowerTrack is a product that provides Enterprise customers the ability to filter a full firehose of data in realtime to receive only the data that they are interested in. Customers can define rules for the Tweets they receive based on a wide variety of dimensions, such as user attributes, geo-location, and language.

Come learn about the PowerTrack architecture that solves technical challenges such as:
  • Filtering data at scale in realtime
  • Application and system layer redundancy to deal with failures
  • Applying configuration changes to open streaming connections
  • Backfilling data to ensure 100% fidelity
  • Managing state of customer streams across data centers And more!
