SettingsParameters Framework (Core Architecture) +- **Smart Hash-based Caching**: Only structural parameters (namespace, config_files, settings_class, env_prefix) affect cache identity +- **Runtime Override System**: `apply_runtime_overrides()` applies kwargs to cached instances without cache invalidation +- **Configuration Processing Pipeline**: File separation, validation, kwargs processing, precedence management +- **LRU Cache Integration**: Works with existing `@lru_cache` on `_get_settings()` + +### 2. SettingsManager Integration +- **Instance Caching**: `get_or_create_settings()` manages settings instances with namespace-based caching +- **Cache Lookup**: `is_namespace_initialised()` checks cache before creating new instances +- **Settings Object Cache**: `settings_object_cache` stores instances by SettingsParameters hash + +### 3. Multi-Source Configuration (via SettingsParameters) +- **File Type Processing**: SettingsFileHandler separates .env, YAML, TOML, JSON files +- **Configuration Validation**: Ensures config files exist and are readable +- **Environment Variable Support**: Prefix-based environment variable loading +- **Kwargs Processing**: Separates Pydantic kwargs from settings field values + +### 4. Template Resolution System +- **Dynamic Template Processing**: `{VARIABLE}` placeholder substitution using existing field values +- **post_init() Integration**: Template resolution during initialization phase +- **Custom Template Logic**: Support for custom post-initialization processing + +### 5. Configuration Precedence Management +- **Source Priority**: Defaults → config files → environment variables → runtime kwargs +- **Override Tracking**: Full traceability of configuration sources +- **Runtime vs Structural Separation**: Critical for cache efficiency + +## Decorator Design + +### Basic Usage + +```python +@mountainash_settings() # All features enabled by default +class AppSettings(BaseSettings): + app_name: str = Field(default="MyApp") + debug: bool = Field(default=False) +``` + +### Feature Selection + +```python +@mountainash_settings( + cache=True, # Enable smart caching + templates=True, # Enable template resolution + multi_format=True, # Enable YAML/TOML/JSON support + namespace="my_app" # Set default namespace +) +class AppSettings(BaseSettings): + # Class definition remains pure Pydantic + pass +``` + +### Disable All Features (Pure Pydantic) + +```python +@mountainash_settings(cache=False, templates=False, multi_format=False) +class AppSettings(BaseSettings): + # Behaves exactly like BaseSettings + pass +``` + +## Implementation Architecture + +### Decorator Function Structure + +```python +def mountainash_settings( + cache: bool = True, + templates: bool = True, + multi_format: bool = True, + namespace: Optional[str] = None +): + """ + Decorator that enhances Pydantic BaseSettings with mountainash-settings features. + + Args: + cache: Enable SettingsParameters-based caching + templates: Enable template string resolution + multi_format: Enable YAML/TOML/JSON config file support + namespace: Default settings namespace + """ + def decorator(cls: Type[BaseSettings]) -> Type[BaseSettings]: + # Enhancement logic here + return enhanced_class + return decorator +``` + +### Class Enhancement Process + +The decorator performs the following enhancements: + +1. **Preserve Original Class**: No inheritance changes +2. **Inject Methods**: Add `.get_settings()`, template resolution +3. **Enhance `__init__`**: Add SettingsParameters handling +4. **Add Metaclass Magic**: Handle caching and multi-format loading +5. **Maintain Pydantic Behavior**: All standard features work normally + +### Method Injection Details + +#### Enhanced `__init__` Method + +```python +def enhanced_init(self, + config_files: Optional[List[str]] = None, + settings_parameters: Optional[SettingsParameters] = None, + namespace: Optional[str] = None, + env_prefix: Optional[str] = None, + **kwargs): + """Enhanced __init__ that integrates with SettingsParameters infrastructure.""" + + # 1.

The decorator handles it automatically +params = SettingsParameters.create( + namespace="api_service", + # settings_class=APISettings, ← Not needed! + config_files=["api_config.yaml"], + base_url="https://prod-api.example.com", + api_key="secret-key-123" +) + +# The decorator merges and validates automatically +settings = APISettings(settings_parameters=params) +print(settings.base_url) # "https://prod-api.example.com" - Works perfectly! +``` + +This works through intelligent parameter merging - see [SettingsParameters Merging Guide](settings_parameters_merging.md) for detailed explanation of how this feature works. + +#### Advanced: Dynamic Settings Class Resolution + +For enterprise applications, SettingsParameters can carry class type information throughout your application, enabling powerful dynamic resolution patterns: + +```python +# Setup: SettingsParameters with embedded class information +database_params = SettingsParameters.create( + namespace="production_db", + settings_class=DatabaseSettings, # ← Type information travels with params + host="prod-db.example.com" +) + +redis_params = SettingsParameters.create( + namespace="production_cache", + settings_class=RedisSettings, # ← Different class type + host="redis.example.com" +) + +# Generic resolution - caller doesn't need to know the class type! +def get_settings_for_service(service_name: str, configs: dict) -> BaseSettings: + params = configs[service_name] + return get_settings(settings_parameters=params) # Dynamic resolution! + +# Usage +service_configs = {"database": database_params, "cache": redis_params} +db = get_settings_for_service("database", service_configs) # Gets DatabaseSettings +cache = get_settings_for_service("cache", service_configs) # Gets RedisSettings +``` + +This enables powerful enterprise patterns like microservices configuration, multi-tenant setups, and plugin architectures.

This creates unnecessary runtime overhead and complicates optional dependency management. This document outlines a comprehensive refactoring plan using modern Python typing patterns inspired by narwhals' sophisticated approach. + +## Current State Analysis + +### Problem Statement + +The package's `SUPPORTED_DATAFRAMES` type union forces all modules to import every dataframe library, even when only handling specific backends: + +```python +# Current approach in types.py +SUPPORTED_DATAFRAMES = Union[pa.Table, pd.DataFrame, pl.DataFrame, pl.LazyFrame, ir.Table, nw.DataFrame, nw.LazyFrame] +``` + +This results in: +- **140+ unnecessary imports** across 42 files +- **Runtime overhead** from loading unused libraries +- **Poor optional dependency handling** +- **Increased memory footprint** +- **Slower package initialization** + +### Impact Analysis + +| Module | Files | Unnecessary Imports | Primary Backend | +|--------|-------|-------------------|-----------------| +| cast/ | 11 | ~55 | Backend-specific | +| join/ | 6 | ~30 | Backend-specific | +| reshape/ | 13 | ~65 | Backend-specific | +| dataframe_utils | 1 | All required | Multi-backend | + +## Proposed Solution Architecture + +### Core Principles + +1. **TYPE_CHECKING blocks**: Import types only during type checking, not runtime +2. **String annotations**: Use forward references for types +3. **Lazy loading**: Defer imports until actually needed +4. **Granular typing**: Backend-specific type aliases +5. **Runtime guards**: Graceful handling of missing optional dependencies + +### Implementation Strategy + +#### Phase 1: Enhanced Type System Foundation + +Create a new `typing_utils.py` module with sophisticated type definitions: + +```python +from __future__ import annotations + +from typing import TYPE_CHECKING, TypeVar, Union, Protocol, TypeAlias +from typing_extensions import TypeGuard + +if TYPE_CHECKING: + import pandas as pd + import polars as pl + import pyarrow as pa + import ibis.expr.types as ir + import narwhals as nw + +# Type aliases for each backend

+NarwhalsFrame: TypeAlias = "nw.DataFrame" +NarwhalsLazyFrame: TypeAlias = "nw.LazyFrame" + +# Composite types +PolarsFrameTypes: TypeAlias = Union[PolarsFrame, PolarsLazyFrame] +NarwhalsFrameTypes: TypeAlias = Union[NarwhalsFrame, NarwhalsLazyFrame] + +# Main union type using string literals +SupportedDataFrames: TypeAlias = Union[ + PandasFrame, + PolarsFrame, + PolarsLazyFrame, + PyArrowTable, + IbisTable, + NarwhalsFrame, + NarwhalsLazyFrame +] + +# Generic type variables for flexibility +DataFrameT = TypeVar("DataFrameT", bound=SupportedDataFrames) +DataFrameT_co = TypeVar("DataFrameT_co", bound=SupportedDataFrames, covariant=True) +DataFrameT_contra = TypeVar("DataFrameT_contra", bound=SupportedDataFrames, contravariant=True) + +# Backend-specific type variables +PandasT = TypeVar("PandasT", bound=PandasFrame) +PolarsT = TypeVar("PolarsT", bound=PolarsFrameTypes) +IbisT = TypeVar("IbisT", bound=IbisTable) +PyArrowT = TypeVar("PyArrowT", bound=PyArrowTable) +NarwhalsT = TypeVar("NarwhalsT", bound=NarwhalsFrameTypes) +``` + +#### Phase 2: Runtime Availability System + +Create `runtime_imports.py` for managing optional dependencies: + +```python +import sys +from typing import Any, Optional + +# Runtime availability flags +PANDAS_AVAILABLE = False +POLARS_AVAILABLE = False +PYARROW_AVAILABLE = False +IBIS_AVAILABLE = False +NARWHALS_AVAILABLE = False + +# Lazy import holders +_pandas: Optional[Any] = None +_polars: Optional[Any] = None +_pyarrow: Optional[Any] = None +_ibis: Optional[Any] = None +_narwhals:

elif "ibis" in type_name: + return "ibis" + elif "narwhals" in type_name: + return "narwhals" + else: + raise ValueError(f"Unknown dataframe type: {type(data)}") +``` + +#### Phase 3: Refactor Strategy Classes + +Transform existing strategy classes to use TYPE_CHECKING: + +```python +# Example: cast/cast_from_pandas.py +from __future__ import annotations + +from typing import TYPE_CHECKING, Any, Optional + +from ..runtime_imports import import_pandas, import_polars +from .base_cast_strategy import BaseCastDataFrame + +if TYPE_CHECKING: + import pandas as pd + import polars as pl + from

raise ImportError("polars is not installed") + return pl.from_pandas(df) +``` + +#### Phase 4: Factory Pattern Optimization + +Refactor factory classes for lazy loading: + +```python +# cast/cast_factory.py +from __future__ import annotations + +from typing import TYPE_CHECKING, Any, Dict, Type, Optional +from ..runtime_imports import get_backend_for_type + +if TYPE_CHECKING: + from

False + + @classmethod + def _lazy_init(cls): + """Lazy load strategies only when needed""" + if cls._initialized: + return + + # Import strategies based on available backends + from ..runtime_imports import ( + PANDAS_AVAILABLE, + POLARS_AVAILABLE, + PYARROW_AVAILABLE, + IBIS_AVAILABLE, + NARWHALS_AVAILABLE + ) + + if PANDAS_AVAILABLE: + from .cast_from_pandas import CastFromPandas + cls._strategies["pandas"] = CastFromPandas + + if POLARS_AVAILABLE: + from .cast_from_polars import CastFromPolars + cls._strategies["polars"] = CastFromPolars + + # ... similar for other backends + +

cls._strategies: + raise ValueError(f"No strategy available for backend: {backend}") + + return cls._strategies[backend] +``` + +#### Phase 5: Public API Updates + +Update public API functions to use string annotations: + +```python +# dataframe_utils.py +from __future__ import annotations + +from typing import TYPE_CHECKING, Optional, List, Dict, Any + +if TYPE_CHECKING: + from .typing_utils

140+ | ~30 | 78% reduction | +| Optional dep handling | Poor | Excellent | Graceful degradation | + +### Type Safety Guarantees +- ✅ Full type checking preserved with mypy +- ✅ IDE autocomplete maintained +- ✅ Runtime type validation available +- ✅ Backward compatibility ensured + +## Testing Strategy + +### Unit Tests +```python +# tests/test_typing_utils.py +def test_type_checking_imports(): + """Ensure types are available during type checking""" + from mountainash_dataframes.typing_utils import SupportedDataFrames + assert SupportedDataFrames is not None +

public API maintains backward compatibility + +### Performance Tests +```python +# tests/test_performance.py +def test_import_time(): + """Measure package import time""" + import time + start = time.time() + import mountainash_dataframes + elapsed = time.time() - start + assert elapsed < 1.0 # Should import in under 1 second +``` + +## Risk Assessment & Mitigation + +| Risk | Impact | Likelihood | Mitigation | +|------|--------|------------|------------| +| Breaking changes | High | Low | Extensive testing, gradual rollout | +| Type checking issues | Medium | Medium | Validate with mypy strict mode | +| Runtime errors | High | Low | Comprehensive error handling | +| Performance regression | Low | Low | Benchmark before/after | + +## Success Criteria + +1. **Import Performance**: 80% reduction in import time +2. **Memory Usage**: 50% reduction in base memory footprint +3. **Type Safety**: Zero mypy errors in strict mode +4. **Test Coverage**: Maintain >90% coverage +5. **Backward Compatibility**: All existing tests pass + +## Appendix: Narwhals-Inspired Patterns + +### Advanced Type Variables +```python +# Covariant and contravariant types for better type inference +DataFrameT_co = TypeVar("DataFrameT_co", bound=SupportedDataFrames, covariant=True) +DataFrameT_contra = TypeVar("DataFrameT_contra", bound=SupportedDataFrames, contravariant=True) +``` + +### Protocol-Based Typing +```python +class DataFrameLike(Protocol): + """Protocol for dataframe-like objects""" + def shape(self) -> tuple[int, int]: ... + def columns(self) -> list[str]: ... +``` + +### Type Guards +```python +def is_pandas_dataframe(df: SupportedDataFrames) -> TypeGuard[PandasFrame]: + """Type guard for pandas DataFrames""" + pd = import_pandas() + return pd is not None and isinstance(df, pd.DataFrame) +``` + +## Conclusion + +This refactoring will transform mountainash-dataframes into a modern, performant package with sophisticated typing that rivals leading dataframe libraries.
