lookup function is for lookup join in Flink [1]. I have the same question as @zinking . normally lookup functions fit better for point query storage systems (like JDBC). let's discuss the two scenarios separately * small Iceberg table that can fit into memory comfortably using caching. In this case, cache should always be enabled. I don't see a reason where cache should be disabled. * large Iceberg table. would FLILP-204 [2] help?
