### **Doris BloomFilter use precautions**
1. It does not support the creation of Bloom Filter indexes for Tinyint,
Float, and Double columns.
2. The Bloom Filter index only has an acceleration effect on in and =
filtering queries.

满足以下几个条件时可以考虑对某列建立Bloom Filter 索引:
-1. 首先BloomFilter适用于非前缀过滤.
-2. 查询会根据该列高频过滤,而且查询条件大多是in和 = 过滤.
-3. 不同于Bitmap,
BloomFilter适用于高基数列。比如UserID。因为如果创建在低基数的列上,比如”性别“列,则每个Block几乎都会包含所有取值,导致BloomFilter索引失去意义
