Datomic features and specs

• Immutability
  Datomic employs an append-only data model where data is never overwritten but instead appended, ensuring historical data is always available and providing strong consistency.
• Time Travel Queries
  Datomic allows you to query the database as of any point in time, facilitating auditing and debugging by allowing easy access to historical data states.
• Rich Data Model
  Supports complex data types like maps and sets directly within its schema, providing a flexible way to represent data.
• ACID Transactions
  Datomic supports fully ACID-compliant transactions, ensuring reliable and predictable database operations.
• Scalability

• Cost
  Can be expensive to operate, especially in a cloud environment, where costs increase with the amount of data stored and the compute resources required.

  Due to its append-only design, Datomic can have limited write throughput, which may not be suitable for applications with heavy write requirements.
• Closed Source
  Datomic is a proprietary database system, which may not appeal to organizations that prefer open-source solutions.
• Learning Curve
  Requires a learning curve as its conceptual model and query language are different from traditional databases, potentially requiring additional training.
