可执行实验

语言: English | 简体中文

本仓库是已完成的参考项目,因此每个实验都是一项可执行测试,而不是教学章节。

机制(Mechanism) 实验(Experiment)
顺序扫描与索引扫描(SeqScan vs IndexScan) tests/unit/planner/test_scan_choice.py
嵌套循环与哈希连接(NestedLoop vs HashJoin) tests/unit/planner/test_join_choice.py
缓冲区固定(buffer pins)与 Clock 淘汰 tests/unit/storage/test_buffer_pool.py
读已提交与可重复读(Read Committed vs Repeatable Read) tests/concurrency/test_read_phenomena.py
写入者冲突与死锁 tests/concurrency/test_write_conflicts.py, tests/concurrency/test_deadlock.py
数据写入前先写预写式日志(WAL before data) tests/reliability/test_wal_before_data.py
提交/检查点的崩溃位置 tests/crash/test_commit_matrix.py, tests/crash/test_checkpoint_matrix.py
REDO 与索引重建 tests/reliability/test_engine_recovery.py, tests/reliability/test_index_rebuild.py
长生命周期快照阻止清理(Vacuum) tests/integration/test_vacuum_reuse.py
仅堆元组(HOT)保留索引根 tests/integration/test_hot_update.py
阶段闭环 tests/acceptance/

使用 uv run pytest -q 运行所有实验。
