From f25817f5c780c2cede653810ed374a109d7aae46 Mon Sep 17 00:00:00 2001 From: Raman369AI Date: Wed, 27 Aug 2025 22:37:05 -0500 Subject: [PATCH 01/18] Add SQLite-based memory service implementation This commit introduces a new SqliteMemoryService that provides persistent storage for agent memory using SQLite with async operations via aiosqlite. Features: - Persistent storage with SQLite database - Async operations using aiosqlite for non-blocking database access - Keyword-based search matching InMemoryMemoryService behavior - User isolation by app_name and user_id - Automatic database initialization with optimized indexes - Additional utility methods: clear_memory() and get_memory_stats() - Duplicate entry prevention with UNIQUE constraints - Content filtering for empty or invalid events Implementation follows existing ADK patterns: - Extends BaseMemoryService with @override decorators - Similar interface to InMemoryMemoryService and VertexAi services - Comprehensive test coverage with 24 test cases - Code formatted with project standards (isort + pyink) Dependencies: - Added aiosqlite>=0.20.0 dependency to pyproject.toml - Updated memory module __init__.py to export SqliteMemoryService Testing: - Complete test suite in tests/unittests/memory/test_sqlite_memory_service.py - All 24 tests passing covering initialization, CRUD operations, search, user isolation, memory management, and edge cases --- .gitignore | 14 + pyproject.toml | 1 + src/google/adk/memory/__init__.py | 2 + .../adk/memory/sqlite_memory_service.py | 266 ++++++++++++++ .../memory/test_sqlite_memory_service.py | 337 ++++++++++++++++++ 5 files changed, 620 insertions(+) create mode 100644 src/google/adk/memory/sqlite_memory_service.py create mode 100644 tests/unittests/memory/test_sqlite_memory_service.py diff --git a/.gitignore b/.gitignore index 6f398cbf9e..2245f2edec 100644 --- a/.gitignore +++ b/.gitignore @@ -92,6 +92,20 @@ uv.lock docs/_build/ site/ +# Claude Code specific +CLAUDE.md.bak +*.claude +.claude/ +claude_context/ +claude_logs/ + +# SQLite databases (development only) +*.db +*.sqlite +*.sqlite3 +memory.db +agent_memory.db + # Misc .DS_Store Thumbs.db diff --git a/pyproject.toml b/pyproject.toml index e89c9656b9..a28dabe709 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -27,6 +27,7 @@ dependencies = [ # go/keep-sorted start "PyYAML>=6.0.2, <7.0.0", # For APIHubToolset.
