## 索引策略
|
||
|
||
### 主要索引类型
|
||
|
||
1. **B-Tree索引**（默认）：主键、外键、常规查询字段
|
||
2. **GIN索引**：JSONB字段、数组字段、全文搜索
|
||
3. **部分索引**：带WHERE条件的索引（如 `WHERE deleted = false`）
|
||
4. **表达式索引**：函数索引（如 `lower(email)`）
|
||
|
||
### 关键索引示例
|
||
|
||
```sql
|
||
-- 部分索引（减少索引大小）
|
||
CREATE INDEX idx_xxx ON table_name(column) WHERE deleted = false;
|
||
|
||
-- GIN索引（数组查询）
|
||
CREATE INDEX idx_xxx ON table_name USING gin(array_column);
|
||
|
||
-- 全文搜索索引
|
||
CREATE INDEX idx_xxx ON table_name USING gin(text_column gin_trgm_ops);
|
||
|
||
-- 表达式索引
|
||
CREATE INDEX idx_xxx ON table_name(lower(email));
|
||
```

## 性能优化建议
|
||
|
||
### 查询优化
|
||
|
||
1. **使用索引**：WHERE、JOIN、ORDER BY字段都要有索引
|
||
2. **避免SELECT ***：只查询需要的字段
|
||
3. **使用LIMIT**：分页查询限制返回行数
|
||
4. **使用EXPLAIN**：分析查询计划
|
||
|
||
### 批量操作
|
||
|
||
```sql
|
||
-- 批量插入（使用COPY或批量INSERT）
|
||
COPY table_name FROM '/path/to/file.csv' WITH CSV;
|
||
|
||
-- 批量更新（使用UPDATE...FROM）
|
||
UPDATE table_name t
|
||
SET column = data.value
|
||
FROM (VALUES (1, 'a'), (2, 'b')) AS data(id, value)
|
||
WHERE t.id = data.id;
|
||
```
|
||
|
||
### 定期维护
|
||
|
||
```sql
|
||
-- 分析表（更新统计信息）
|
||
ANALYZE table_name;
|
||
|
||
-- 清理和分析
|
||
VACUUM ANALYZE table_name;
|
||
|
||
-- 重建索引
|
||
REINDEX TABLE table_name;
|
||
```
