Does Impala support parallel query execution?

Yes, Impala supports parallel query execution. By utilizing Impala’s parallel execution feature, users can run multiple queries simultaneously, improving query efficiency and performance. Impala can execute queries on different nodes at the same time, utilizing cluster resources for parallel computing, thereby speeding up data processing. Impala also supports dynamic resource allocation and adjustment, automatically allocating and adjusting resources based on query needs to achieve more efficient parallel query execution. Therefore, Impala is a distributed query engine suitable for processing large-scale data and supporting parallel query execution.
