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

What's new?

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