无法更改 cassandra 列的数据类型

Question

对于这张桌子

mytable(
    id text PRIMARY KEY,
    before_creation_hour int,
   ... creation_hour bigint,
...)

当我尝试更改 before_creation_hour 的类型时，出现错误

cqlsh:codingjedi> alter table mytable
              ... alter before_creation_hour type bigint;
InvalidRequest: Error from server: code=2200 [Invalid query] message="Altering of types is not allowed"`

我做错了什么？

好像int不能改成bigint。 - https://docs.datastax.com/en/cql-oss/3.3/cql/cql_reference/cql_data_types_c.html#cql_data_types_c__cql_data_type_compatibility
