We demonstrate AutoExecutor, a predictive system that uses machine learning models to predict query run times as a function of the number of allocated executors, that limits the maximum allowed parallelism, for Spark SQL queries running on Azure Synapse.}, url = {http://approjects.co.za/?big=en-us/research/publication/autoexecutor-predictive-parallelism-for-spark-sql-queries/}, }
