" summary

Describes Barrel, a multi-purpose P2P database implemented in Erlang that emphasizes data locality and peer-to-peer distribution. Covers use of a Facebook RocksDB binding via dirty-nif and cowdb to create a pure Erlang key/value store beyond DETS limits, design choices for read/write concurrency and fault-tolerant I/O, and a custom P2P protocol and presence/claim-space mechanism to distribute data without central bottlenecks.
