H2 vs. Ditto

Ditto is an innovative embedded database tailored for mobile and edge devices, offering much more than typical local storage solutions. Unlike conventional embedded databases that function in a standalone manner, Ditto features integrated peer-to-peer synchronization and edge-aware connectivity, allowing devices to exchange data seamlessly without depending on a central server or a continuous internet connection. At the heart of Ditto lies a CRDT-based (Conflict-Free Replicated Data Type) engine, which ensures robust eventual consistency among distributed nodes, even in scenarios where devices are offline, partitioned, or primarily mobile. This empowers developers to create resilient and collaborative applications, where data remains accessible locally while being automatically synchronized across devices as soon as connections are reestablished. Ditto simplifies connectivity challenges with its dynamic and channel-agnostic discovery process. Devices utilizing Ditto can establish temporary mesh networks through Bluetooth, peer-to-peer Wi-Fi, LAN, cellular networks, or any combination thereof, enabling real-time data synchronization of changes.

Ditto is a mobile database designed to operate primarily offline, allowing it to fit effortlessly into your existing applications. It provides consistent access to data, peer-to-peer synchronization, and resilience in environments with limited connectivity. With Ditto, you can enhance your current mobile infrastructure by adding modern offline functionalities. This solution eliminates the dependency on continuous cloud connectivity or unreliable network links, enabling your application to operate effectively even when completely offline. The integrated synchronization mechanism utilizes peer-to-peer and mesh networking, ensuring devices remain updated without the need for a central server. Whether users are traveling, in basements, flying, or simply out of Wi-Fi reach, Ditto guarantees that their data remains current and is shared instantly with nearby devices. Synchronization occurs automatically via Bluetooth, peer-to-peer Wi-Fi, local area network, or cellular connections, depending on what is available. There’s no need to develop custom synchronization processes or handle conflict resolutions—Ditto takes care of everything for you.

Ditto is a mobile database designed for offline use, ensuring that data remains accessible locally and synchronized across different devices, even in environments without internet connectivity. At its foundation, Ditto utilizes Conflict-Free Replicated Data Types (CRDTs) to automatically handle data conflicts, providing strong eventual consistency without the need for developers to implement custom merging solutions. However, Ditto goes beyond the capabilities of typical offline-first databases. It facilitates seamless synchronization for offline-first applications, even when devices are entirely disconnected. Unique to Ditto is its integrated peer-to-peer and mesh networking capabilities, which enable devices to sync directly with each other without relying on cloud services or server infrastructure. When there is no network connection, Ditto-enabled devices can locate and sync with nearby peers through Bluetooth, peer-to-peer Wi-Fi, LAN, or cellular connections, ensuring that real-time updates are possible, even in challenging environments.
