Under the Hood: Building and open-sourcing RocksDB

Under the Hood: Building and open-sourcing RocksDB | EEDSP | Scoop.it

Every time one of the 1.2 billion people who use Facebook visits the site, they see a completely unique, dynamically generated home page. There are several different applications powering this experience--and others across the site--that require global, real-time data fetching.   

 

Storing and accessing hundreds of petabytes of data is a huge challenge, and we're constantly improving and overhauling our tools to make this as fast and efficient as possible. Today, we are open-sourcing RocksDB, an embeddable, persistent key-value store for fast storage that we built and use here at Facebook.

HyperDex.org: Home of the Searchable Key-Value Store

HyperDex.org: Home of the Searchable Key-Value Store | EEDSP | Scoop.it

HyperDex is a next-generation key-value store with the following features:

Fast HyperDex has lower latency, higher throughput, and lower variance than other key-value stores. Specifically, HyperDex is a factor of 2-14 faster than MongoDB, Cassandra and Redis on the industry-standard YCSB benchmarks.

Searchable HyperDex enables lookups of non-primary data attributes. Such searches are implemented efficiently and contact a small number of servers.

Scalable HyperDex scales as more machines are added to the system.

Consistent The value you GET is always the latest value you PUT. Not just "eventually," but immediately and always.

Fault tolerant HyperDex handles failures. Data is automatically replicated on multiple machines so that failures do not cause data loss.
