Dogma Persistence Toolkit

Abstract persistence primitives for use in Dogma engines, projections, etc.

The persistence toolkit provides a set of relatively low-level persistence abstractions that can be used to build higher-level storage systems.

The interfaces are designed to be easy to implement by placing a minimal set of requirements on each implementation.

Abstractions

• Journal - an append-only log of binary records with optimistic concurrency control
• Keyspace - a non-transactional binary key/value store
• Set - a set of unique binary values

Drivers

Implementations of the above abstractions are called "drivers". Several built-in drivers are included, each in their own package within the driver directory.

• Amazon DynamoDB
• Amazon S3
• PostgreSQL and compatible databases
• In-memory reference/testing implementation
