Datomic: Distributed Database for Scalable Applications
Distributed database designed for scalable, flexible and intelligent applications with ACID transactions, temporal database capabilities and flexible data modeling, well suited for large data sets across multiple servers.
What is Datomic?
Datomic is a distributed database designed from the ground up to enable scalable, flexible and intelligent applications. Some key capabilities and features of Datomic include:
- Distributed architecture - Datomic can run across multiple servers/devices to scale up and handle large data volumes.
- Immutable data model - Datomic treats all data as immutable and accumulates facts over time. This facilitates auditing, historical querying and increases flexibility.
- Datalog support - Datomic allows expressing flexible queries and rules using Datalog, a declarative logic programming language.
- Temporal capabilities - Datomic natively supportsTemporal (time based) queries on data.
- Flexible schemas - Datomic has flexible schemas that allow diverse data shapes within the same database.
- ACID transactions - Datomic provides atomic, consistent, isolated and durable transactions to ensure data integrity.
- Programmatic database interaction through an HTTP API and application integration libraries.
Some typical applications that benefit from Datomic's capabilities include IoT data pipelines, event sourcing systems, audit/compliance logging systems and AI/ML applications that need immutable historical data.
