33-39: LGTM: Improved configurability of SLOW_ACTION_THRESHOLD.The new implementation using
Lazyallows for runtime configuration via an environment variable, which is a good improvement. The parsing logic and fallback mechanism are well-implemented.Consider adding a debug log when the environment variable is successfully parsed, to aid in configuration verification:
if let Ok(value) = env::var("FLOW_RUNTIME_SLOW_ACTION_THRESHOLD") { if let Ok(parsed) = value.parse() { tracing::debug!("FLOW_RUNTIME_SLOW_ACTION_THRESHOLD set to {} ms", parsed); Duration::from_millis(parsed) } else { tracing::warn!("Invalid FLOW_RUNTIME_SLOW_ACTION_THRESHOLD value: {}", value); Duration::from_millis(300) } } else { Duration::from_millis(300) }engine/runtime/geometry/src/types/line_string.rs (3)
487-491: LGTM! Consider a minor optimization.The implementation for converting
LineString2D<T>toGeoLineString<T>looks correct and efficient. It properly handles the coordinate conversion while maintaining type safety.Consider using
mapinstead ofinto_iter().map()for a slightly more concise implementation:impl<T: CoordNum> From<LineString2D<T>> for GeoLineString<T> { fn from(line_string: LineString2D<T>) -> Self { - GeoLineString(line_string.0.into_iter().map(|c| c.x_y().into()).collect()) + GeoLineString(line_string.0.into_iter().map(|c| c.x_y().into()).collect()) } }This change doesn't affect functionality but slightly simplifies the code.
493-503: LGTM! Consider a minor optimization.The implementation for converting
GeoLineString<T>toLineString2D<T>is correct and efficient. It properly handles the coordinate conversion while maintaining type safety.Consider using
mapinstead ofinto_iter().map()for a slightly more concise implementation:impl<T: CoordNum> From<GeoLineString<T>> for LineString2D<T> { fn from(line_string: GeoLineString<T>) -> Self { LineString2D::new( line_string - .0 - .into_iter() + .0 .map(|c| coordinate::Coordinate2D::new_(c.x, c.y)) .collect(), ) } }This change doesn't affect functionality but slightly simplifies the code.
486-503: Enhances interoperability between geometry typesThese new implementations for converting between
LineString2D<T>andGeoLineString<T>are valuable additions to the codebase. They improve the interoperability between different geometry representations, which aligns well with the PR's objective of refactoring geometry handling.The bidirectional conversion capability allows for seamless integration with both internal (
LineString2D) and external (GeoLineString) geometry representations, potentially simplifying operations that involve different geometry libraries or formats.Consider adding unit tests for these new conversion implementations to ensure their correctness and to guard against potential regressions in future changes.

576-586: Implementation looks correct, but consider performance optimization.The
From<Polygon2D<T>> for GeoPolygon<T>implementation correctly converts between the two polygon types, handling both exterior and interior rings. However, the use ofclone()might impact performance for large polygons.Consider using
std::mem::take()orinto_iter()instead ofclone()if the originalPolygon2D<T>is no longer needed after conversion. This could potentially improve performance, especially for large polygons with many vertices.
588-598: Implementation is correct, but consider performance optimization.The
From<GeoPolygon<T>> for Polygon2D<T>implementation correctly converts between the two polygon types, handling both exterior and interior rings. However, similar to the previous implementation, the use ofclone()might impact performance for large polygons.Consider using
std::mem::take()orinto_iter()instead ofclone()if the originalGeoPolygon<T>is no longer needed after conversion. This could potentially improve performance, especially for large polygons with many vertices.
576-598: Summary: Good addition of bidirectional conversion between polygon types.The new implementations for converting between
Polygon2D<T>andGeoPolygon<T>enhance the interoperability of the custom geometry types with thegeo-typeslibrary. This addition aligns well with the PR objective of refactoring geometry handling.A few points to consider:
- The implementations are correct and handle both exterior and interior rings of the polygons.
- There's potential for performance optimization by avoiding
clone()operations, especially for large polygons.- These conversions may be useful in other parts of the codebase where integration with
geo-typesis needed.Overall, these changes contribute positively to the geometry handling capabilities of the engine.
Consider adding unit tests for these new conversion implementations to ensure their correctness and to guard against potential regressions in the future.

74-75: Consider stronger memory ordering for atomic operationsUsing
Ordering::Relaxedmay not provide sufficient synchronization guarantees for your use case. To ensure proper visibility across threads, consider usingOrdering::SeqCstorOrdering::Acquire/Releasefor your atomic operations.Apply this diff to strengthen the memory ordering:
self.thread_counter - .fetch_add(1, std::sync::atomic::Ordering::Relaxed); + .fetch_add(1, std::sync::atomic::Ordering::SeqCst);And:
self.thread_counter - .fetch_sub(1, std::sync::atomic::Ordering::Relaxed); + .fetch_sub(1, std::sync::atomic::Ordering::SeqCst);engine/runtime/runtime/src/forwarder.rs (1)
56-57: Review necessity of cloningwriterandfeatureCloning
writerandfeaturebefore moving them into the asynchronous task may have performance implications, especially if these structures are large. Verify if cloning is necessary, or if using reference-counted pointers likeArcorRccan optimize resource usage.engine/runtime/geometry/src/types/multi_polygon.rs (1)
278-288: Nitpick: Enhance consistency by using intermediate variables.For better readability and consistency with the second implementation, consider assigning the collected polygons to a variable before constructing
GeoMultiPolygon. This mirrors the structure used in the implementation starting at line 290.Apply this diff to improve readability:
impl<T: CoordNum> From<MultiPolygon2D<T>> for GeoMultiPolygon<T> { fn from(mpolygon: MultiPolygon2D<T>) -> Self { - GeoMultiPolygon( - mpolygon - .0 - .into_iter() - .map(GeoPolygon::from) - .collect::<Vec<_>>(), - ) + let polygons = mpolygon + .0 + .into_iter() + .map(GeoPolygon::from) + .collect::<Vec<_>>(); + GeoMultiPolygon(polygons) } }engine/runtime/action-processor/src/geometry/area_on_area_overlayer.rs (4)
130-133: Review the hardcoded number of threadsThe
num_threadsmethod returns a hardcoded value of10. It's advisable to ensure that this number aligns with the system's capabilities and the application's performance requirements. Consider making it configurable or providing justification for choosing this specific value.
164-166: Handle buffer failures explicitlyWhen
buffer_polygonreturnsNone, the code silently exits the function withreturn Ok(()). This might make debugging difficult if polygons fail to process without any notification. Consider logging a warning or error to notify of the buffer failure.
174-176: Handle buffer failures explicitly in loopSimilar to the previous comment, within the loop processing multiple polygons, failures from
buffer_polygonare silently ignored. Adding logging or error handling here would improve transparency and ease troubleshooting.
194-196: Handle buffer failures explicitly when inserting into RTreeIn this section, if
buffer_polygonfails, the function returns without any notification. Explicitly handling or logging the failure would aid in identifying issues during execution.

SLOW_ACTION_THRESHOLDconfigurable via an environment variable. This improvement allows for easier tuning of performance logging without requiring recompilation. The implementation usingonce_cell::sync::Lazyensures efficient lazy evaluation of the threshold.These changes align well with the PR objective of refactoring for improved async support, as they provide more flexibility in runtime configuration, which can be beneficial for different deployment scenarios or performance tuning needs.
engine/runtime/geometry/src/types/polygon.rs (1)
4-4: Import statement looks good.The new import for
geo_types::Polygonwith the aliasGeoPolygonis correctly placed and helps avoid naming conflicts with the localPolygontype.engine/runtime/geometry/src/algorithm/bufferable.rs (3)
1-2: Import statement is appropriateThe
usestatement correctly importsbuffer_multi_polygonfrom thegeo_buffercrate, allowing for buffering operations on multi-polygons using external library functionality.
63-66:buffer_polygonfunction correctly buffers aPolygon2DThe
buffer_polygonfunction effectively converts the inputPolygon2Dinto aMultiPolygon2D, delegates the buffering operation tobuffer_multi_polygon, and safely returns the first polygon from the result as anOption<Polygon2D<f64>>. This correctly handles the possibility of an empty result.
68-73: Efficient delegation inbuffer_multi_polygonThe
buffer_multi_polygonfunction appropriately delegates the buffering task togeo_buffer_multi_polygon, ensuring that the buffering logic leverages the externalgeo_buffercrate. The use of.into()for type conversion before and after the function call correctly adapts between the crate's internal types and the external library's types.engine/runtime/geometry/src/types/multi_polygon.rs (2)
278-288: Approved: Correct implementation ofFrom<MultiPolygon2D<T>> for GeoMultiPolygon<T>.The
Fromtrait implementation accurately convertsMultiPolygon2D<T>intoGeoMultiPolygon<T>by mapping each internalPolygonto aGeoPolygon. This enhances interoperability with external geometric libraries and is implemented correctly.
290-299: Approved: Correct implementation ofFrom<GeoMultiPolygon<T>> for MultiPolygon2D<T>.The reverse conversion is correctly handled by mapping each
GeoPolygonback into aPolygon2D. This ensures seamless data transformation between the externalgeo_typesand the internal geometric representations.engine/runtime/action-processor/src/geometry/area_on_area_overlayer.rs (3)
297-297: Verify if the overlap count attribute is correctly setThe
output_attributeis set toAttributeValue::Number(1.into()), indicating an overlap count of 1 for each individual feature. Ensure that this aligns with the intended logic, especially since overlaps are being calculated elsewhere with potentially higher counts.
313-313: Confirm correct overlap count assignmentWhen creating new features from overlapping polygons, the
output_attributeis set to the variablepolygon_feature, which represents the count of overlapping features. Verify that this value accurately reflects the intended overlap count for the combined feature.
320-320:⚠️ Potential issueHandle potential
unwraponNoneAt
features.first().unwrap(), there is an implicit assumption thatfeaturesis not empty. Iffeaturescould be empty, this would cause a panic at runtime. Consider adding a check or handling the possibility of an emptyfeaturesvector.Apply this diff to safely handle empty features:
- epsg: features.first().unwrap().geometry.as_ref().unwrap().epsg, + epsg: if let Some(geom) = features.first().and_then(|f| f.geometry.as_ref()) { + geom.epsg + } else { + // Handle the case where features is empty or the geometry is missing + return; + },Likely invalid or redundant comment.
