[ANNOUNCE] New committer: Lucas Bradstreet
Hi, Everyone, The PMC of Apache Kafka is pleased to announce a new Kafka committer Lucas Bradstreet. Lucas has been a long time Kafka contributor since Oct. 2018. He has been extremely valuable for Kafka on both performance and correctness improvements. The following are his performance related contributions. KAFKA-9820: validateMessagesAndAssignOffsetsCompressed allocates batch iterator which is not used KAFKA-9685: Solve Set concatenation perf issue in AclAuthorizer KAFKA-9729: avoid readLock in authorizer ACL lookups KAFKA-9039: Optimize ReplicaFetcher fetch path KAFKA-8841: Reduce overhead of ReplicaManager.updateFollowerFetchState The following are his correctness related contributions. KAFKA-13194: LogCleaner may clean past highwatermark KAFKA-10432: LeaderEpochCache is incorrectly recovered on segment recovery for epoch 0 KAFKA-9137: Fix incorrect FetchSessionCache eviction logic Congratulations, Lucas! Thanks, Jun (on behalf of the Apache Kafka PMC)
