feat: Add Memory Import/Export Functionality (JSON/CSV) #213

NTLx · 2026-01-31T06:54:22Z

This PR adds full support for importing and exporting memories, addressing Issue #137.

This contribution is part of the OceanBase AI Coding Event.

🚀 Features

Export: Export memories to JSON (full data) or CSV (spreadsheet compatible).
Import: Bulk import memories from JSON or CSV files.
API Support: New endpoints GET /v1/memories/export and POST /v1/memories/import.

🛠 Implementation

Utils: Created src/powermem/utils/io.py for robust serialization logic.
Core: Updated Memory class with export_memories and import_memories methods.
API: Added streaming response for exports and file upload for imports.

✅ AI Contribution Details

Design: Implemented a layered architecture (Utils -> Core -> API) for maintainability.
Formats: Chose JSON for fidelity and CSV for accessibility.
Performance: Used streaming for large exports.

You've modified some code that isn't related to this feature.

src/powermem/core/memory.py

            # Merge custom_importance_evaluation_prompt from top level if present
            if self.memory_config.custom_importance_evaluation_prompt:
                cfg["custom_importance_evaluation_prompt"] = self.memory_config.custom_importance_evaluation_prompt
-            # Merge memory_decay config if present (for Ebbinghaus algorithm parameters)


LGTM on the main logic, but these extra changes might belong elsewhere.
