[GitHub] [incubator-doris] CrazyJugger opened a new issue #4865: doris 前缀索引问题
CrazyJugger opened a new issue #4865:
URL: https://github.com/apache/incubator-doris/issues/4865
在前置索引与rollup 中 “我们将一行数据的前 36 个字节 作为这行数据的前缀索引” 下面第一个例子中 “以下表结构的前缀索引为 user_id(8Byte) + age(4Bytes) + message(prefix 20 Bytes)。” 这只有32字节，这个是一个单纯的例子 还是写错了 是否message 不是prefix 20 bytes 而是22 bytes

This is my fault, It should be the first 36 bytes as the prefix index. The example should be update.

This is indeed wrong. It should be the first 32 bytes as the prefix index. The latter example is correct.
Could you please help us to change it? It is very easy to change the doc.
