It focuses on query, compute, and analysis. DLI optimizes performance and reconstructs services based on open-source Spark. It is compatible with the Apache Spark ecosystem and interfaces, and improves performance by 2.5x when compared with open-source Spark. In this way, DLI enables you to perform query and analysis of EB's of data within hours.</li><li id="dli_01_0378__li14792133295711">Flink is a distributed compute engine that is ideal for batch processing, that is, for processing static data sets and historical data sets.
