The Decahose delivers a 10% random sample of the realtime Twitter Firehose through a streaming connection. This is accomplished via a realtime sampling algorithm which randomly selects the data, while still allowing for the expected low-latency delivery of data as it is sent through the firehose by Twitter.
Below are some of the features available with Decahose:
- Expanded and enhanced URLs: - fully unwinds shortened URLs and provides additional metadata (page title and description)
- Stream partitioning - 2 partitions, each containing 50% of volume of the Decahose stream
- Enhanced reliability - geographic diversity of backend systems
Note: This data is delivered in bulk, and does not support additional filtering (e.g. for keywords).
