Fisher.NET Event Store and Document Database on SQLite

Marten-inspired event sourcing and document storage in a single file, with no database server at all

No server, one file

Fisher runs inside your process. There is nothing to install, nothing to provision, and nothing to keep running — a store is a SQLite file you can copy, back up, or throw away.

Document Database

A full document database with LINQ querying — joins, grouping, aggregates and both paging styles — plus soft deletes, patching, hierarchies, bulk insert and optimistic concurrency.

Event Store

Event sourcing with every projection shape across every lifecycle, an async projection daemon, subscriptions, DCB tags, natural keys, masking and stream compacting.
