gavinchou opened a new pull request, #32404:
URL: https://github.com/apache/doris/pull/32404
* doris 2.0.x 版本还有遗留的问题, delete handler 将 predicate 表达式转成一个字
符串持久化了, 然后在使用的时候通过正则提取字段名 比较符号 以及值来还原
predicate. 这个序列化和正则匹配的过程是非常tricky并且是不鲁棒的.
* doris 2.0.x 不允许使用中文列名, 否则有delete 语句可能会导致BE coredump
* 2.1 引入了 sub_predicate_v2 解决了转成字符串再持久化的问题,
但是为了保证兼容, master分支最好也修一下(需要单独提PR, 因为不一样了)
