Eventory #

Work in progress

An event sourcing-inspired library targeting offline-first use, with automatic synchronization with remote instances when connection is available.

Design Principles #

All events are acceptable. Errors are managed when looking at the data, not when writing.
Writers control the instant events happen.
Event value serialization mechanism can be chosen by library users.
EventSource is immutable and represents the state of the world at a precise moment in time.
EventorySink must be able to write as fast as possible.
Snapshots allow EventSources to be extremely efficient at querying data.
EventSource and EventorySink are always separate entities even when using the same storage mechanism.
Reloading an EventSource with new events from an EventorySink or remote stream must be extremely cheap.
