From c22e0f9c3f808cb68c953dfabb1f0ba750f2cf36 Mon Sep 17 00:00:00 2001 From: Leo Meyerovich Date: Thu, 8 Jan 2026 21:07:52 -0800 Subject: [PATCH 001/195] feat(gfql): add WHERE clause and df_executor (stacked PR) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add WHERE clause support with Yannakakis-style df_executor for efficient same-path constraint evaluation. New modules: - same_path_types.py: WHERE clause data structures and parsing - same_path_plan.py: Query plan generation - df_executor.py: Yannakakis-based execution engine Features: - Chain.where field for WHERE clause constraints - StepColumnRef and WhereComparison types - Same-path filtering using semi-join reduction - Support for adjacent and non-adjacent column comparisons Tests: - test_df_executor_core.py: Core WHERE functionality - test_df_executor_patterns.py: Graph pattern tests - test_df_executor_amplify.py: Amplification tests - test_df_executor_dimension.py: Dimension tests - test_same_path_plan.py: Query plan tests Note: This is a stacked PR on top of chain optimizations. Some tests are failing and need fixes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- graphistry/compute/chain.py | 16 +- graphistry/compute/gfql/df_executor.py | 2069 +++++++++++++++ graphistry/compute/gfql/same_path_plan.py | 62 + graphistry/compute/gfql/same_path_types.py | 107 + graphistry/compute/gfql_unified.py | 64 +- graphistry/tests/compute/test_chain_where.py | 49 + tests/gfql/ref/conftest.py | 47 + tests/gfql/ref/test_chain_optimizations.py | 81 + tests/gfql/ref/test_df_executor_amplify.py | 2237 ++++++++++++++++ tests/gfql/ref/test_df_executor_core.py | 2306 ++++++++++++++++ tests/gfql/ref/test_df_executor_dimension.py | 1910 +++++++++++++ tests/gfql/ref/test_df_executor_patterns.py | 2509 ++++++++++++++++++ tests/gfql/ref/test_same_path_plan.py | 18 + 13 files changed, 11466 insertions(+), 9 deletions(-) create mode 100644 graphistry/compute/gfql/df_executor.py create mode 100644 graphistry/compute/gfql/same_path_plan.py create mode 100644 graphistry/compute/gfql/same_path_types.py create mode 100644 graphistry/tests/compute/test_chain_where.py create mode 100644 tests/gfql/ref/test_df_executor_amplify.py create mode 100644 tests/gfql/ref/test_df_executor_core.py create mode 100644 tests/gfql/ref/test_df_executor_dimension.py create mode 100644 tests/gfql/ref/test_df_executor_patterns.py create mode 100644 tests/gfql/ref/test_same_path_plan.py diff --git a/graphistry/compute/chain.py b/graphistry/compute/chain.py index 775a94c965..23a4be4bca 100644 --- a/graphistry/compute/chain.py +++ b/graphistry/compute/chain.py @@ -1,6 +1,6 @@ import logging import pandas as pd -from typing import Dict, Union, cast, List, Tuple, Optional, TYPE_CHECKING +from typing import Dict, Union, cast, List, Tuple, Sequence, Optional, TYPE_CHECKING from graphistry.Engine import Engine, EngineAbstract, df_concat, df_to_engine, resolve_engine from graphistry.Plottable import Plottable @@ -12,6 +12,11 @@ from .typing import DataFrameT from .util import generate_safe_column_name from graphistry.compute.validate.validate_schema import validate_chain_schema +from graphistry.compute.gfql.same_path_types import ( + WhereComparison, + parse_where_json, + where_to_json, +) from .gfql.policy import PolicyContext, PolicyException from .gfql.policy.stats import extract_graph_stats @@ -37,9 +42,11 @@ class Chain(ASTSerializable): def __init__( self, chain: List[ASTObject], + where: Optional[Sequence[WhereComparison]] = None, validate: bool = True, ) -> None: self.chain = chain + self.where = list(where or []) if validate: # Fail fast on invalid chains;

This caused test_forward_captures_alias_frames_and_prunes and test_forward_minmax_prune_matches_oracle to fail since the original WHERE feature commit (3d3bc9f7). Added _apply_forward_where_pruning() which: - For equality constraints (==): Intersects values between aliases and prunes both frames to only rows with matching values - For inequality constraints (<, <=, >, >=): Applies range-based pruning using min/max bounds from the other alias - Iterates to fixed-point for equality constraints to handle transitive pruning This implements the forward constraint propagation phase of Yannakakis-style semijoin reduction. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- graphistry/compute/gfql/df_executor.py | 114 +++++++++++++++++++++++++ 1 file changed, 114 insertions(+) diff --git a/graphistry/compute/gfql/df_executor.py b/graphistry/compute/gfql/df_executor.py index 83eeb6b004..d3543df5ff 100644 --- a/graphistry/compute/gfql/df_executor.py +++ b/graphistry/compute/gfql/df_executor.py @@ -142,6 +142,9 @@ def _forward(self) -> None: self.forward_steps.append(g_step) self._capture_alias_frame(op, g_step, idx) + # Forward pruning: apply WHERE clause constraints to captured frames + self._apply_forward_where_pruning() + def _capture_alias_frame( self, op: ASTObject, step_result: Plottable, step_index: int ) -> None: @@ -173,6 +176,117 @@ def _capture_alias_frame( alias_frame = frame[subset_cols].copy() self.alias_frames[alias] = alias_frame + def _apply_forward_where_pruning(self) -> None: + """Apply WHERE clause constraints to prune alias frames forward. + + For each WHERE clause, if one alias has known values from pattern filters, + propagate those constraints to other aliases in the clause. + + This handles cases like: + - Chain: a:account -> r -> c:user{id=user1} + - WHERE: a.owner_id == c.id + - Since c.id is constrained to {user1}, we prune a to owner_id IN {user1} + """ + if not self.inputs.where: + return + + # Iterate until no more pruning happens (fixed-point) + changed = True + while changed: + changed = False + for clause in self.inputs.where: + left_alias = clause.left.alias + right_alias = clause.right.alias + left_col = clause.left.column + right_col = clause.right.column + + left_frame = self.alias_frames.get(left_alias) + right_frame = self.alias_frames.get(right_alias) + + if left_frame is None or right_frame is None: + continue + if left_col not in left_frame.columns or right_col not in right_frame.columns: + continue + + if clause.op == "==": + # Equality: values must match + left_values = series_values(left_frame[left_col]) + right_values = series_values(right_frame[right_col]) + common = left_values & right_values + + # Prune left frame + if left_values != common: + new_left = left_frame[left_frame[left_col].isin(common)] + if len(new_left) < len(left_frame): + self.alias_frames[left_alias] = new_left + changed = True + + # Prune right frame + if right_values != common: + new_right = right_frame[right_frame[right_col].isin(common)] + if len(new_right) < len(right_frame): + self.alias_frames[right_alias] = new_right + changed = True + + elif clause.op == "!=": + # Inequality: no simple pruning possible without full join + pass + + elif clause.op in {"<", "<=", ">", ">="}: + # Min/max constraints: prune based on range overlap + self._apply_minmax_forward_prune( + clause, left_alias, right_alias, left_col, right_col + ) + # Don't set changed for minmax - it's a one-shot prune + + def _apply_minmax_forward_prune( + self, + clause: "WhereComparison", + left_alias: str, + right_alias: str, + left_col: str, + right_col: str, + ) -> None: + """Apply min/max constraint pruning for inequality comparisons. + + For a.score < c.score: + - Prune a to rows where a.score < max(c.score) + - Prune c to rows where c.score > min(a.score) + """ + left_frame = self.alias_frames.get(left_alias) + right_frame = self.alias_frames.get(right_alias) + if left_frame is None or right_frame is None: + return + + left_vals = left_frame[left_col] + right_vals = right_frame[right_col] + + # Get bounds + left_min, left_max = left_vals.min(), left_vals.max() + right_min, right_max = right_vals.min(), right_vals.max() + + if clause.op == "<": + # left < right: left must be < max(right), right must be > min(left) + new_left = left_frame[left_vals < right_max] + new_right = right_frame[right_vals > left_min] + elif clause.op == "<=": + new_left = left_frame[left_vals <= right_max] + new_right = right_frame[right_vals >= left_min] + elif clause.op == ">": + # left > right: left must be > min(right), right must be < max(left) + new_left = left_frame[left_vals > right_min] + new_right = right_frame[right_vals < left_max] + elif clause.op == ">=": + new_left = left_frame[left_vals >= right_min] + new_right = right_frame[right_vals <= left_max] + else: + return + + if len(new_left) < len(left_frame): + self.alias_frames[left_alias] = new_left + if len(new_right) < len(right_frame): + self.alias_frames[right_alias] = new_right + def _should_attempt_gpu(self) -> bool: """Decide whether to try GPU kernels for same-path execution."""

Engine.py: Add type coercion in safe_merge for cuDF empty DataFrame columns - df_executor.py: Use engine-aware DataFrame construction for allowed node/edge frames - bfs.py: Add _df_cons helper, use set-based visited tracking instead of indicator merge - edge_semantics.py: Replace .tolist() with series_values() - multihop.py: Use engine-aware DataFrame construction and set-based anti-join - post_prune.py: Use engine-aware DataFrame/Series construction, concat_frames - where_filter.py: Refactor to use concat_frames instead of pd.concat - hop.py: Add _series_to_list helper for cuDF Series conversion - test_str.py: Fix has_cudf() to test actual GPU availability - test_df_executor_core.py: Fix incorrect test assertion for node result set Key fixes: - Replace pd.DataFrame({...}) with engine-aware construction - Replace pd.Series(...) with engine-aware Series - Replace pd.concat with concat_frames (handles pandas/cudf mixing) - Replace .tolist() with series_values() for set conversion - Replace merge(..., indicator=True) with set-based filtering (cuDF limitation) - Add type coercion for empty DataFrame columns in safe_merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- ai/README.md | 35 +++-- graphistry/Engine.py | 27 ++++ graphistry/compute/gfql/df_executor.py | 33 +++-- graphistry/compute/gfql/same_path/bfs.py | 39 ++++-- .../compute/gfql/same_path/edge_semantics.py | 7 +- graphistry/compute/gfql/same_path/multihop.py | 42 ++++-- .../compute/gfql/same_path/post_prune.py | 45 +++++-- .../compute/gfql/same_path/where_filter.py | 122 ++++++------------ graphistry/compute/hop.py | 10 ++ .../tests/compute/predicates/test_str.py | 34 +++-- tests/gfql/ref/test_df_executor_core.py | 3 +- 11 files changed, 252 insertions(+), 145 deletions(-) diff --git a/ai/README.md b/ai/README.md index a4ed7403f6..8e1f952679 100644 --- a/ai/README.md +++ b/ai/README.md @@ -184,19 +184,38 @@ WITH_BUILD=0 WITH_TEST=0 ./test-cpu-local.sh ### GPU Testing -

Removed list() wrappers in .isin() calls since pd.Index works directly Files changed: df_executor.py, bfs.py, df_utils.py, edge_semantics.py, multihop.py, post_prune.py, where_filter.py 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- graphistry/compute/gfql/df_executor.py | 66 +++++---- graphistry/compute/gfql/same_path/bfs.py | 11 +- graphistry/compute/gfql/same_path/df_utils.py | 128 +++++++++++++++++- .../compute/gfql/same_path/edge_semantics.py | 4 +- graphistry/compute/gfql/same_path/multihop.py | 17 +-- .../compute/gfql/same_path/post_prune.py | 20 +-- .../compute/gfql/same_path/where_filter.py | 18 +-- 7 files changed, 192 insertions(+), 72 deletions(-) diff --git a/graphistry/compute/gfql/df_executor.py b/graphistry/compute/gfql/df_executor.py index 0ab5132ece..0c8dbf446d 100644 --- a/graphistry/compute/gfql/df_executor.py +++ b/graphistry/compute/gfql/df_executor.py @@ -220,17 +220,17 @@ def _apply_forward_where_pruning(self) -> None: # Equality: values must match left_values = series_values(left_frame[left_col]) right_values = series_values(right_frame[right_col]) -

Supports equality, inequality, and comparison operators on named alias columns. - **GFQL / cuDF same-path**: Added execution-mode gate `GRAPHISTRY_CUDF_SAME_PATH_MODE` (auto/oracle/strict) for GFQL cuDF same-path executor. Auto falls back to oracle when GPU unavailable; strict requires cuDF or raises. - **Compute / hop**: Added `GRAPHISTRY_HOP_FAST_PATH` (set to `0`/`false`/`off`) to disable fast-path traversal for benchmarking or compatibility checks. +- **GFQL / WHERE**: Added opt-in `GRAPHISTRY_NON_ADJ_WHERE_MULTI_EQ_SEMIJOIN` for multi-equality semijoin pruning (2-hop, experimental). ### Performance - **Compute / hop**: Refactored hop traversal to precompute node predicate domains and unify direction handling; synthetic CPU benchmarks show modest median improvements with some regressions on undirected/range scenarios. - **GFQL / WHERE**: Use DF-native forward pruning for cuDF equality constraints to avoid host syncs (pandas path unchanged). +- **GFQL / WHERE**: Default non-adjacent WHERE mode now `auto`, enabling value-mode + domain semijoin auto, with edge semijoin auto for edge clauses (opt-out via env). - **Compute / hop**: Undirected traversal skips oriented-pair expansion when no destination filters;

mid-intersection sizes to help diagnose dense multi-clause blowups. ### Tests - **GFQL / df_executor**: Added comprehensive test suite (core, amplify, patterns, dimension) with 200+ tests covering
