When a sort operation spills to disk, the in-memory data must be sorted and merged before being written to a file. This setting reserves a specific amount of memory for that in-memory sort/merge process. Note: This setting is irrelevant if the sort operation cannot spill (i.e., if there's no `DiskManager` configured). | | datafusion.execution.sort_in_place_threshold_bytes | 1048576 | When sorting, below what size should data be concatenated and sorted in a single RecordBatch rather than sorted in batches and merged. | | datafusion.execution.meta_fetch_concurrency | 32 | Number of files to read in parallel when inferring schema and statistics | From 836f92e3617c3dc744efc3f776fdf67e809a8184 Mon Sep 17 00:00:00 2001 From: wiedld Date: Mon, 9 Dec 2024 16:20:29 -0800 Subject: [PATCH 5/9] Revert "Account for constant equivalence properties in union, tests (#12562)" This reverts commit 577e4bba0f5838846862621e1f5318c949cff2cb. --- .../physical-expr-common/src/sort_expr.rs | 7 - .../physical-expr/src/equivalence/class.rs | 49 +- .../src/equivalence/properties.rs | 433 ++++-------------- 3 files changed, 81 insertions(+), 408 deletions(-) diff --git a/datafusion/physical-expr-common/src/sort_expr.rs b/datafusion/physical-expr-common/src/sort_expr.rs index 9ae12fa9f608..6036032ddc7b 100644 --- a/datafusion/physical-expr-common/src/sort_expr.rs +++ b/datafusion/physical-expr-common/src/sort_expr.rs @@ -118,13 +118,6 @@ impl PhysicalSortExpr { } } -/// Access the PhysicalSortExpr as a PhysicalExpr -impl AsRef for PhysicalSortExpr { - fn as_ref(&self) -> &(dyn PhysicalExpr + 'static) { - self.expr.as_ref() - } -} - impl PartialEq for PhysicalSortExpr { fn eq(&self, other: &PhysicalSortExpr) -> bool { self.options == other.options && self.expr.eq(&other.expr) diff --git a/datafusion/physical-expr/src/equivalence/class.rs b/datafusion/physical-expr/src/equivalence/class.rs index e4185ad44d65..162e076fa461 100644 --- a/datafusion/physical-expr/src/equivalence/class.rs +++ b/datafusion/physical-expr/src/equivalence/class.rs @@ -29,6 +29,7 @@ use datafusion_common::tree_node::{Transformed, TransformedResult, TreeNode}; use datafusion_common::JoinType; use datafusion_physical_expr_common::physical_expr::format_physical_expr_list; +#[derive(Debug, Clone)] /// A structure representing a expression known to be constant in a physical execution plan. /// /// The `ConstExpr` struct encapsulates an expression that is constant during the execution @@ -39,10 +40,9 @@ use datafusion_physical_expr_common::physical_expr::format_physical_expr_list; /// /// - `expr`: Constant expression for a node in the physical plan. /// -/// - `across_partitions`: A boolean flag indicating whether the constant -/// expression is the same across partitions.
