## What is the purpose of the change Backport #28135 to `release-2.3`. This fixes duplicate serialization in `AdaptiveLoadBasedRecordWriter#broadcastEmit`. The method already serializes the record once before iterating over all subpartitions; the loop should reuse that serialized buffer instead of calling the record-based emit overload, which serializes the same record again for each subpartition. ## Brief change log - Reuse the serialized broadcast record buffer in `AdaptiveLoadBasedRecordWriter#broadcastEmit`. ## Verifying this change - `./mvnw -pl flink-runtime -am -Dtest=AdaptiveLoadBasedRecordWriterTest -Dsurefire.failIfNoSpecifiedTests=false test` -- This is an automated message from the Apache Git Service.
