* BE 的数据存储目录可以显式的指定为 SSD 或者 HDD（通过 .SSD 或者 .HDD 后缀区分）。建表时，可以统一指定所有 Partition 初始存储的介质。注意，后缀作用是显式指定磁盘介质，而不会检查是否与实际介质类型相符。

* 注意，当指定 storage_medium 时，该参数只是一个“尽力而为”的设置。即使集群内没有设置 SSD 存储介质，也不会报错，而是自动存储在可用的数据目录中。同样，如果 SSD 介质不可访问、空间不足，都可能导致数据初始直接存储在其他可用介质上。而数据到期迁移到 HDD 时，如果 HDD 介质不可访问、空间不足，也可能迁移失败（但是会不断尝试）。

* The BE data storage directory can be explicitly specified as SSD or HDD (differentiated by .SSD or .HDD suffix). When you build a table, you can uniformly specify the media for all Partition initial storage. Note that the suffix is to explicitly specify the disk media without checking to see if it matches the actual media type.
* The default initial storage media can be specified by `default_storage_medium= XXX` in the fe configuration file `fe.conf`, or, if not, by default, HDD. If specified as an SSD, the data is initially stored on the SSD.
- * If storage\_cooldown\_time is not specified, the data is automatically migrated from the SSD to the HDD after 7 days by default. If storage\_cooldown\_time is specified, the data will not migrate until the storage_cooldown_time time is reached.
+ * If storage\_cooldown\_time is not specified, the data is automatically migrated from the SSD to the HDD after 30 days by default. If storage\_cooldown\_time is specified, the data will not migrate until the storage_cooldown_time time is reached.
* Note that this parameter is just a "best effort" setting when storage_medium is specified. Even if no SSD storage media is set in the cluster, no error is reported and it is automatically stored in the available data directory. Similarly, if the SSD media is inaccessible and out of space, the data may initially be stored directly on other available media. When the data expires and is migrated to the HDD, if the HDD media is inaccessible and there is not enough space, the migration [...]
