This pull request introduce a way to sort append-only table with z-order(mainly). This topo will be like:  * We use rangePartitioner to make global sort by the z-order of the given columns. Now assume that all the columns are 8 bytes, which mean, if you index a string by z-order, the useful bytes are only the front eight. * We use 512 M for sort memory on heap. A usage example is : <pre> flink run ./paimon-flink-action-0.5-SNAPSHOT.jar order-rewrite --warehouse /Users/yejunhao/paimontest/GlobalBatchReadWrite --database my_db --table Orders1 --select "SELECT * FROM my_db.Orders1 WHERE f0 = 0" --order-by "zorder(f1,f2)" </pre> -- This is an automated message from the Apache Git Service.
