In case you missed it: In April we released Datomic 1.0.7622, a big, feature-filled changelog with several performance improvements. It includes:

-
Performance: Reduce log write amplification for systems with many transactions

New API: list-backups, which lists the timepoints available in a backup repository

Performance: Reduce CPU and memory required to calculate index metrics

Fix: Regression introduced in 1.0.7556 which broke the ddb-local protocol
