- 全字段匹配：所有列完全相同的记录
- 指定字段匹配：只比较指定的字段
保留策略
| 策略 | 说明 |
|---|---|
first | 保留第一条重复记录 |
last | 保留最后一条重复记录 |
none | 删除所有重复记录 |
mark | 标记重复但不删除（添加is_duplicate列） |
使用方法
全字段去重
python scripts/run_duplicate_detector_exact.py \
--input data.csv \
--output deduped.csv
按指定字段去重
python scripts/run_duplicate_detector_exact.py \
--input data.csv \
--output deduped.csv \
--subset "name,phone"
标记重复
python scripts/run_duplicate_detector_exact.py \
--input data.csv \
--output marked.csv \
--keep mark
参数说明
| 参数 | 必填 | 说明 |
