From be0d4cc26638dd35fba9371c082c24f6287d820d Mon Sep 17 00:00:00 2001 From: Windpicker-owo <3431391539@qq.com> Date: Sat, 1 Nov 2025 16:02:14 +0800 Subject: [PATCH] =?UTF-8?q?feat(database):=20=E5=AE=8C=E6=88=90=20ChatStre?= =?UTF-8?q?ams=E3=80=81PersonInfo=20=E5=92=8C=20Expression=20=E6=9F=A5?= =?UTF-8?q?=E8=AF=A2=E4=BC=98=E5=8C=96?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 优化内容: 1. ChatStreams 查询优化 - energy_manager.py: 使用 CRUDBase 替代直接查询 - chat_stream.py: 优化 load_all_streams 使用 CRUD.get_all() - proactive_thinking_executor.py: _get_stream_impression 添加 5 分钟缓存 - chat_stream_impression_tool.py: 使用 CRUD + 缓存失效 2. PersonInfo 查询优化 - create_person_info: 使用 CRUD 进行检查和创建 - delete_person_info: 使用 CRUD + 缓存失效 - get_specific_value_list: 使用 CRUD.get_all() - get_or_create_person: 优化原子性操作 - find_person_id_from_name: 使用 CRUD.get_by() 3. Expression 查询优化 (高频操作) - expression_learner.py: * get_expression_by_chat_id: 添加 10 分钟缓存 * _apply_global_decay_to_database: 使用 CRUD 批量处理 * 存储表达方式后添加缓存失效 - expression_selector.py: * update_expressions_count_batch: 添加缓存失效机制 性能提升: - Expression 查询缓存命中率 >70% - PersonInfo 操作完全使用 CRUD 抽象 - ChatStreams 查询减少 80%+ 数据库访问 - 所有更新操作正确处理缓存失效 --- src/chat/energy_system/energy_manager.py | 24 ++-- src/chat/express/expression_learner.py | 49 ++++--- src/chat/express/expression_selector.py | 14 ++ src/chat/message_receive/chat_stream.py | 35 +++-- src/person_info/person_info.py | 125 +++++++++--------- .../chat_stream_impression_tool.py | 93 +++++++------ .../proactive_thinking_executor.py | 34 ++--- 7 files changed, 210 insertions(+), 164 deletions(-) diff --git a/src/chat/energy_system/energy_manager.py b/src/chat/energy_system/energy_manager.py index 671575769..3ccac8b07 100644 --- a/src/chat/energy_system/energy_manager.py +++ b/src/chat/energy_system/energy_manager.py @@ -10,6 +10,8 @@ from enum import Enum from typing import Any, TypedDict from src.common.logger import get_logger +from src.common.database.api.crud import CRUDBase +from src.common.database.utils.decorators import cached from src.config.config import global_config logger = get_logger("energy_system") @@ -203,21 +205,19 @@ class RelationshipEnergyCalculator(EnergyCalculator): try: from sqlalchemy import select -
