From b9afafc55ac1fe7394463554debf53d9960c97e6 Mon Sep 17 00:00:00 2001 From: Nitin Kanukolanu Date: Tue, 10 Mar 2026 14:24:31 -0400 Subject: [PATCH 01/14] feat(geo): add geo_distance() function with full operator support - Add GeoDistanceCondition and GeoDistanceSelect dataclasses - Support POINT(lat, lon) syntax (latitude-first, Google Maps style) - Default unit: meters (SQL standard) - Support operators: <, <=, >, >=, BETWEEN - Route <, <= to FT.SEARCH GEOFILTER (optimized) - Route >, >=, BETWEEN to FT.AGGREGATE with FILTER - Add geo_distance() in SELECT for distance calculations --- sql_redis/analyzer.py | 4 + sql_redis/parser.py | 189 ++++++++++++++++++++++++++++++++++++---- sql_redis/translator.py | 134 +++++++++++++++++++++++++++- 3 files changed, 309 insertions(+), 18 deletions(-) diff --git a/sql_redis/analyzer.py b/sql_redis/analyzer.py index f7504c7..6a974d6 100644 --- a/sql_redis/analyzer.py +++ b/sql_redis/analyzer.py @@ -84,6 +84,10 @@ def analyze(self, parsed: ParsedQuery) -> AnalyzedQuery: for condition in parsed.conditions: referenced_fields.add(condition.field) + # Fields from geo_conditions + for geo_cond in parsed.geo_conditions: + referenced_fields.add(geo_cond.field) + # Fields from aggregations for agg in parsed.aggregations: if agg.field: diff --git a/sql_redis/parser.py b/sql_redis/parser.py index 037bcd9..96eab6f 100644 --- a/sql_redis/parser.py +++ b/sql_redis/parser.py @@ -48,6 +48,36 @@ class Condition: negated: bool = False +@dataclass +class GeoDistanceCondition: + """A GEO distance condition with coordinates. + + Represents: geo_distance(field, POINT(lat, lon), unit) < radius + User provides POINT(lat, lon), internally stored as (lon, lat) for Redis. + """ + + field: str + lon: float + lat: float + radius: float | tuple[float, float] # Single value or (low, high) for BETWEEN + operator: str # '<', '<=', '>', '>=', 'BETWEEN' + unit: str = "m" # m, km, mi, ft (default: meters) + + +@dataclass +class GeoDistanceSelect: + """A geo_distance() call in SELECT clause for FT.AGGREGATE APPLY. + + User provides POINT(lat, lon), internally stored as (lon, lat) for Redis. + """ + + field: str + lon: float + lat: float + alias: str + unit: str = "m" # m, km, mi, ft (default: meters) + + @dataclass class ParsedQuery: """Result of parsing a SQL query.""" @@ -55,6 +85,8 @@ class ParsedQuery: index: str = "" fields: list[str] = dataclasses.field(default_factory=list) conditions: list[Condition] = dataclasses.field(default_factory=list) + geo_conditions: list[GeoDistanceCondition] = dataclasses.field(default_factory=list) + geo_distance_selects: list[GeoDistanceSelect] = dataclasses.field(default_factory=list) boolean_operator: str = "AND" aggregations: list[AggregationSpec] = dataclasses.field(default_factory=list) computed_fields: list[ComputedField] = dataclasses.field(default_factory=list) @@ -245,6 +277,9 @@ def _process_select_expression_inner( field=field_name, alias=alias or func_name, ) + elif func_name == "geo_distance": + # geo_distance(field, POINT(lon, lat), unit) in SELECT + self._process_geo_distance_select(expression, result, alias) elif func_name in redis_reducers: # Redis-specific reducer functions field_name = None @@ -297,6 +332,48 @@ def _process_vector_distance( alias=alias or "vector_distance", ) + def _process_geo_distance_select( + self, expression, result: ParsedQuery, alias: str | None + ) -> None: + """Process geo_distance() in SELECT clause for FT.AGGREGATE APPLY.""" + func_args = expression.expressions + if not func_args: + return + + field_name = None + geo_lon = None + geo_lat = None + geo_unit = "m" # Default to meters for geodistance() + + # First arg: field name + if isinstance(func_args[0], exp.Column): + field_name = func_args[0].name + + # Second arg: POINT(lat, lon) -
