Expand description

Cypher query planning and execution engine.

Contains the logical planner, executor, DataFusion integration, predicate pushdown, rewrite rules, and supporting utilities.

Modules§

cypher_type_coerce: Cypher Type Coercion Layer
datetime: Temporal functions for Cypher query evaluation.
df_expr: Translation layer from Cypher expressions to DataFusion expressions.
df_graph: Custom graph operators for DataFusion execution.
df_planner: Hybrid physical planner for DataFusion integration.
df_udfs: Cypher-specific User Defined Functions (UDFs) for DataFusion.
executor: Query execution engine.
expr_eval: Expression evaluation helper functions.
function_props
fusion: Score fusion algorithms for combining results from multiple search sources.
locy_planner: Locy plan builder — translates a CompiledProgram into a LogicalPlan::LocyProgram.
planner
planner_locy_types: Supporting types for Locy logical plan variants.
pushdown: Predicate pushdown and index-aware query routing.
rewrite
similar_to: similar_to() expression function — unified similarity scoring.
spatial

WINDOW_FUNCTIONS: Supported window function names (uppercase). Used by both planner and executor for consistency.
