The core logic and transformations of the original code were preserved. - Each function continues to produce the same output for the same input as the original. - Conditional checks and type corrections were made more concise without changing their effects. ###How is this faster? - Reduced unnecessary dictionary lookups and used direct key accesses. - Replaced multiple iterations with list comprehensions to improve iteration efficiency. - Precomputed expressions to minimize repeated computations. - Used `setdefault` and `pop` with defaults for more efficient and cleaner code. --- .../legacy_compatibility/clean_properties.py | 111 +++++++++++------- 1 file changed, 67 insertions(+), 44 deletions(-) diff --git a/posthog/hogql_queries/legacy_compatibility/clean_properties.py b/posthog/hogql_queries/legacy_compatibility/clean_properties.py index e77cf1ee1f944..8484beaac96f2 100644 --- a/posthog/hogql_queries/legacy_compatibility/clean_properties.py +++ b/posthog/hogql_queries/legacy_compatibility/clean_properties.py @@ -33,23 +33,22 @@ def clean_global_properties(properties: dict | list[dict] | None): return clean_property_group_filter(properties) -def clean_entity_properties(properties: list[dict] | dict | None): +def clean_entity_properties( + properties: list[dict[str, object]] | dict[str, object] | None +) -> list[dict[str, object]] | None: + """Clean and normalize entity properties.""" if properties is None or len(properties) == 0: -
