Happy belated new year! The Datomic team was among the six hundred participants at Clojure/Conj 2025. Here are some highlights.
Everything gets better when data moves closer to processing. Datomic can extensively cache its immutable data without concern for coordination or invalidation.
With the 'valcache' feature in today’s Datomic On-Prem release you can use your local SSDs as large, durable per-process caches, on both transactors and peers. Valcache can improve performance, reduce the read load on storage and stay hot across process restarts.
Today’s releases of Datomic Cloud and Datomic On-prem include two major new features: tuples and database predicates.
Most Datomic queries return tuples, but sometimes you just want maps. Today’s release of the Datomic Cloud client library adds return maps to Datomic datalog. For example, the following query uses the new :keys clause to request maps with :artist and :release keys:
Today’s releases of Datomic On-prem include a new feature: query-stats.
query-stats is a new feature that gives users visibility into the decisions made by the query engine while it processed your query.
