Remove ABC interface classes and inline method docstrings

[jhamon]

Summary

This PR removes ABC interface classes that were only used to store docstrings and moves all documentation directly to the implementation methods. This simplifies the codebase by eliminating unnecessary abstraction layers while preserving all documentation.

Changes Made

Removed Interface Classes

• Deleted pinecone/db_data/interfaces.py (IndexInterface)
• Deleted pinecone/db_data/index_asyncio_interface.py (IndexAsyncioInterface)
• Deleted pinecone/pinecone_interface_asyncio.py (PineconeAsyncioDBControlInterface)

Updated Implementation Classes

• pinecone/db_data/index.py - Removed IndexInterface inheritance
• pinecone/db_data/index_asyncio.py - Added docstrings to all methods, removed IndexAsyncioInterface inheritance
• pinecone/pinecone_asyncio.py - Added docstrings to all methods, removed PineconeAsyncioDBControlInterface inheritance

Why These Changes Were Made

The ABC interface classes (IndexInterface, IndexAsyncioInterface, and PineconeAsyncioDBControlInterface) were serving no functional purpose beyond storing docstrings. They added unnecessary complexity to the codebase without providing any runtime benefits:

• No type checking or enforcement (methods were already implemented)
• No shared implementation (all methods were abstract with pass)
• Documentation was the only content in these classes

By inlining the docstrings directly into the implementation methods, we:

• Reduce code complexity (net -1,503 lines)
• Improve maintainability (documentation lives with implementation)
• Eliminate unnecessary inheritance chains
• Maintain full API documentation (all docstrings preserved)

Implementation Details

1. Docstring Migration: All docstrings were moved from interface methods to their corresponding implementation methods, maintaining:

   • Full RST syntax compatibility (.. code-block::, .. admonition::, :param:, :type:, etc.)
   • All code examples and usage patterns
   • Parameter descriptions and return type documentation

2. Import Cleanup: Removed all imports of the interface classes from implementation files

3. Inheritance Removal: Removed interface class inheritance from:

   • Index(PluginAware, IndexInterface) → Index(PluginAware)
   • _IndexAsyncio(IndexAsyncioInterface) → _IndexAsyncio
   • PineconeAsyncio(PineconeAsyncioDBControlInterface) → PineconeAsyncio

4. Verification:

   • All docstrings verified for consistency with method implementations
   • Code examples validated for syntactic correctness
   • RST syntax verified for Sphinx compatibility
   • No linter errors introduced

Impact

• Lines Changed: -1,503 net lines (removed 3,240, added 1,737)
• Files Changed: 6 files (3 deleted, 3 modified)
• Breaking Changes: None - all public APIs remain unchanged
• Documentation: Fully preserved - all docstrings maintained

Note

Simplifies the SDK by removing unused abstract interface layers and moving their documentation directly into concrete classes. Public APIs remain unchanged; functionality is unaffected.

• Deleted db_data/interfaces.py, db_data/index_asyncio_interface.py, and pinecone_interface_asyncio.py
• Dropped interface inheritance from Index, _IndexAsyncio, and PineconeAsyncio
• Migrated and expanded method docstrings/examples into implementations across index_asyncio.py and pinecone_asyncio.py
• Minor import cleanups; no runtime logic changes
