CRDT Principles and Synchronization Patterns for Local-First Software
Mathematical foundations and synchronization patterns of Conflict-free Replicated Data Types (CRDTs) enabling offline-capable, collaborative local-first applications.
Local-First software prioritizes local storage as primary, allowing uninterrupted user workflows during network disconnections and automated state resolution upon reconnection.
1. Algebraic Properties
CRDTs rely on mathematical properties (commutativity, associativity, idempotence) to guarantee that replicas converge without central locks or conflict dialogues.
2. Operational Considerations
Choosing between state-based and operation-based variants involves tradeoffs in network bandwidth, memory consumption, and tombstone cleanup strategies.
