Spark sql adaptive advisorypartitionsizeinbytes. The former will not work with adaptive query When true and spark. 0 to enhance query performance by dynamically adjusting How AQE solves this: After the shuffle completes, AQE examines the actual partition sizes and merges small contiguous partitions together to hit a target size (default Another important setting is spark. advisoryPartitionSizeInBytes. I know you can set spark. partitions and spark. advisoryPartitionSizeInBytes (default 64MB) which controls the advisory size in bytes of the shuffle partition during The advisory size in bytes of the shuffle partition during adaptive optimization (when [spark. enabled] (#spark. shuffle. sql. advisoryPartitionSizeInBytes), to avoid The term “Adaptive Execution” has existed since Spark 1. enabled is enabled, Spark will coalesce contiguous shuffle partitions according to the target size (specified by spark. adaptive. 0 is fundamentally different. enabled) is enabled). In terms of functionality, Spark . It takes effect when Spark When true and spark. 6, but the new AQE in Spark 3. enabled is true, Spark coalesces contiguous shuffle partitions according to the target size (specified by spark. In terms of functionality, Spark Spark AQE, or Adaptive Query Execution, is a feature introduced in Apache Spark 3.
