Purpose
We plan to use Apache Paimon as the cold storage layer for Fluss primary-key tables. The Fluss Flink connector will provide hybrid lookup: active partitions are queried from Fluss, while expired partitions fall back to Paimon.
Since fallback lookups are infrequent and sparse, building a local SST from the entire data file on the first LocalTableQuery access introduces significant and difficult-to-amortize overhead. For this workload, directly pushing primary-key lookups down to the underlying Parquet files should provide better latency and efficiency.
