import "github.com/jrhy/mast"

Primary use cases

Strongly-consistent versioned KV store layer with flexible backends (S3, files today, designed for Dynamo, Firebase, SQL as well)
Provides consistent access to multiple versions of collections or materialized views, with incremental storage cost logarithmically proportional to delta size
Flexible change reporting through efficient diffing of snapshots

v1.2.23 adds func (m *Mast) StartDiff(context.Context, oldMast *Mast) (*DiffCursor, error) for stateful iterating through differences without callbacks
