Parse Engine Compared to other programming languages and ORDER BY to GROUP BY SQL, and they are used to transfer memory merger to stream merger. In the result merger part, stream merger and memory merger will be explained in detail. The overall structure focuses more on the creation of a balanced data source connection, the consumption generated by the memory usage, the maximum utilization of the concurrency and other problems.
