This message covers changes in this release. The complete change log can be found at [Change Log | Datomic](https://docs.datomic.com/changes/pro.html). To download this release see [Datomic Pro Releases | Datomic](https://docs.datomic.com/releases-pro.html) ## 1.0.7745: 2026/10/16 - Feature: allow ddb connections to be parameterized with credentials. See [#'d/connect](https://docs.datomic.com/clojure/index.html#datomic.api/connect) - Performance: Improve indexing performance by merging sorts and tiers in parallel. - Performance: Increase `index-parallelism` limit from 8 to 128. - Performance: Increase the maximum size of transaction batches in high-throughput systems. - Performance: Improve transaction batch I/O pipelining. - Performance: Improve incremental backup throughput in large databases. - Performance: Improve verify-backup throughput by separating ephemeral I/O threads from dedicated deserialization threads. - Fix: Transactions no longer consume entity ids for tempids that resolve to existing entities through upsert. Previously the number of ids consumed depended on the order of the tx-data, so routinely retransacting schema could exhaust the schema element limit even in databases with few attributes. - Fix: Prevent race condition where the futures returned by sync/sync-index/sync-schema/sync-excise API would fail to complete, though the given basis t was available.
