Redis is an open-source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster. ...

...The high-level concept is that all requests to fetch or store an image go through an image pipeline which encapsulates the work of checking the in-memory caches and an on disk cache before retrieving the image from over the network as well as keeping the caches both up to date and pruned. Twitter Image Pipeline came to fruition as numerous needs rose out of Twitter for iOS use cases. The system for image loading prior to TIP was fragile and inefficient with some severe edge cases. Designing a new framework from the ground up to holistically approach the need for loading images was the best route and led to TIP.

A Linux utility that monitors I/O requests going to physical disks and maps the requests to the files for which they were issued. It doesn't monitor file I/O, which can hit the cache. It only tracks file usage that generates disk activity.
