database structureDatomic Pro is a database system that allows you to separate transaction processing, storeage and queries in order to simplify databases.
The new structure that Datomic Pro implements results in a simple data model. Datomic consists of a peer library and the transactor. The first component will be the connection between your server and the database, while the transactor component is designed to implement structure changes.
The Pro version includes the external storage component and can integrate for distributed caching. It supports SQL, Dynamo DB and Infinispan storage and it features a high availability transactor.
Note: In order to use this application, you have to request an evaluation key.
Limitations:
· 30 days trial
What's New in This Release:
· Component entities can now be created as nested maps in transaction data
· Tightened peer HornetQ timeout for faster failover.
· Allow sets as an alternative to lists when specifying values for a cardinality-many attribute in transaction data.
· Fixed bug: Allow the transaction entity to appear in value position only in transaction data.
· Fixed bug: Prevent excessive memory use that would occur before rejecting invalid transaction that attempts to `db.fn/retractEntity` nil.
