It takes effect when Spark coalesces small shuffle partitions or splits skewed shuffle partition.,3.0.0], [spark.sql.adaptive.autoBroadcastJoinThreshold,<undefined>,Configures the maximum size in bytes for a table that will be broadcast to all worker nodes when performing a join. By setting this value to -1 broadcasting can be disabled. The default value is same with spark.sql.autoBroadcastJoinThreshold. Note that, this config is used only in adaptive framework.,3.2.0], [spark.sql.adaptive.coalescePartitions.enabled,true,When true and 'spark.sql.adaptive.enabled' is true, Spark will coalesce contiguous shuffle partitions according to the target size (specified by 'spark.sql.adaptive.advisoryPartitionSizeInBytes'), to avoid too many small tasks.,3.0.0], [spark.sql.adaptive.coalescePartitions.initialPartitionNum,<undefined>,The initial number of shuffle partitions before coalescing. If not set, it equals to spark.sql.shuffle.partitions. This configuration only has an effect when 'spark.sql.adaptive.enabled' and 'spark.sql.adaptive.coalescePartitions.enabled' are both true.,3.0.0], [spark.sql.adaptive.coalescePartitions.minPartitionSize,1MB,The minimum size of shuffle partitions after coalescing. This is useful when the adaptively calculated target size is too small during partition coalescing.,3.2.0], [spark.sql.adaptive.coalescePartitions.parallelismFirst,true,When true, Spark does not respect the target size specified by 'spark.sql.adaptive.advisoryPartitionSizeInBytes' (default 64MB) when coalescing contiguous shuffle partitions, but adaptively calculate the target size according to the default parallelism of the Spark cluster. The calculated size is usually smaller than the configured target size. This is to maximize the parallelism and avoid performance regression when enabling adaptive query execution. It's recommended to set this config to false and respect the configured target size.,3.2.0], [spark.sql.adaptive.customCostEvaluatorClass,<undefined>,The custom cost evaluator class to be used for adaptive execution. If not being set, Spark will use its own SimpleCostEvaluator by default.,3.2.0], [spark.sql.adaptive.enabled,true,When true, enable adaptive query execution, which re-optimizes the query plan in the middle of query execution, based on accurate runtime statistics.,1.6.0], [spark.sql.adaptive.forceOptimizeSkewedJoin,false,When true, force enable OptimizeSkewedJoin even if it introduces extra shuffle.,3.3.0], [spark.sql.adaptive.localShuffleReader.enabled,true,When true and 'spark.sql.adaptive.enabled' is true, Spark tries to use local shuffle reader to read the shuffle data when the shuffle partitioning is not needed, for example, after converting sort-merge join to broadcast-hash join.,3.0.0], [spark.sql.adaptive.maxShuffledHashJoinLocalMapThreshold,0b,Configures the maximum size in bytes per partition that can be allowed to build local hash map. If this value is not smaller than spark.sql.adaptive.advisoryPartitionSizeInBytes and all the partition size are not larger than this config, join selection prefer to use shuffled hash join instead of sort merge join regardless of the value of spark.sql.join.preferSortMergeJoin.,3.2.0], [spark.sql.adaptive.optimizeSkewsInRebalancePartitions.enabled,true,When true and 'spark.sql.adaptive.enabled' is true, Spark will optimize the skewed shuffle partitions in RebalancePartitions and split them to smaller ones according to the target size (specified by 'spark.sql.adaptive.advisoryPartitionSizeInBytes'), to avoid data skew.,3.2.0], [spark.sql.adaptive.optimizer.excludedRules,<undefined>,Configures a list of rules to be disabled in the adaptive optimizer, in which the rules are specified by their rule names and separated by comma.

When false they are read as string literals.,3.4.0], [spark.sql.ansi.enabled,false,When true, Spark SQL uses an ANSI compliant dialect instead of being Hive compliant. For example, Spark will throw an exception at runtime instead of returning null results when the inputs to a SQL operator/function are invalid.For full details of this dialect, you can find them in the section "ANSI Compliance" of Spark's documentation. Some ANSI dialect features may be not from the ANSI SQL standard directly, but their behaviors align with ANSI SQL's style,3.0.0], [spark.sql.ansi.enforceReservedKeywords,false,When true and 'spark.sql.ansi.enabled' is true, the Spark SQL parser enforces the ANSI reserved keywords and forbids SQL queries that use reserved keywords as alias names and/or identifiers for table, view, function, etc.,3.3.0], [spark.sql.ansi.relationPrecedence,false,When true and 'spark.sql.ansi.enabled' is true, JOIN takes precedence over comma when combining relation. For example, `t1, t2 JOIN t3` should result to `t1 X (t2 X t3)`. If the config is false, the result is `(t1 X t2) X t3`.,3.4.0], [spark.sql.autoBroadcastJoinThreshold,10MB,Configures the maximum size in bytes for a table that will be broadcast to all worker nodes when performing a join.  By setting this value to -1 broadcasting can be disabled.
