克隆:克隆时未保留表历史记录(已推迟)

注意

此行为变更最初在 2023_07 捆绑包中,并计划在 2023_08 捆绑包中默认启用。但是,现已推迟,新的发布日期尚未确定。此变更无法进行测试。

克隆表还会克隆与表关联的加载历史记录。

变更前:

克隆表时不会克隆加载历史记录。以前加载到源表中的文件可以重新加载到克隆的表中。

变更后:

The load history is also cloned when a table is cloned. As a result, files are not reloaded and data is not duplicated in the cloned table. Note that truncating the table and using the FORCE = TRUE COPY option override the load history in the cloned table.

It's recommended to check any existing workloads that require table cloning. If the load history information is not required and you want to bypass this behavior, use the FORCE = TRUE COPY option.
