Features adds the cloud_storage_prefetch_segments_max cluster config which can be used to enable small segment prefetching in cloud storage. by @ballard26 in #29795 Bug Fixes Reverted the c-ares DNS resolver from 1.34.7 back to 1.34.6. c-ares 1.34.7 contains an upstream regression (c-ares/c-ares#1256) where a DNS query's completion callback can silently never be invoked, which could leave an inter…
Bug Fixes Fixed an issue where audit-log initialization unconditionally sent a CreateTopics request to the controller leader, causing authentication and the admin API to be rejected cluster-wide (with audit_failure_policy=reject) for the duration of any prolonged leaderless state. Initialization now checks the local topic table first and skips the CreateTopics call when the audit topic already exi…
