    Affects Versions: 2.1.0
            Reporter: Shuai Xu


The motivation of this FLIP aims to introduce Async Key Ordered Lookup Join to Flink, addressing the need to process records in key-specific order (e.g., maintaining update sequence for upsertKey) while enabling concurrent processing of different keys to boost throughput.
