Hi Lu, Currently, Flink does not have official benchmark results compared to Spark and Presto. You can run the TPC-DS benchmark yourself to compare to different engines, Flink supports all queries for TPC-DS, for example, the benchmark project [1]. Of course, other companies have made similar comparisons, such as this document [2], and the results are for reference only.
