Barrel, keep data in sync in your Erlang application
summary
Barrel is an Erlang-built document store that embeds like Mnesia or serves over HTTP/WebSocket, using an Erlang binding to RocksDB backend for storage and an epoched monotonic sequence for change streams; documents carry hash-based revisions (a small blockchain per document) and attachments replicate via HTTP. It implements push-pull master-master replication with peer-to-peer read/write rules, optional synchronous quorum, per-path indexing of every document field, offline sync for devices, and is entering customer testing with a monthly incremental release plan.
