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 may fail (but will continue to try). ### ENGINE diff --git a/docs/documentation/en/sql-reference/sql-statements/Data Definition/CREATE TABLE_EN.md b/docs/documentation/en/sql-reference/sql-statements/Data Definition/CREATE TABLE_EN.md index 129e6c1398..70755ca7d1 100644 --- a/docs/documentation/en/sql-reference/sql-statements/Data Definition/CREATE TABLE_EN.md +++ b/docs/documentation/en/sql-reference/sql-statements/Data Definition/CREATE TABLE_EN.md @@ -206,7 +206,7 @@ Syntax: storage_medium: SSD or HDD, 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. storage_cooldown_time: If storage_medium is SSD, data will be automatically moved to HDD when timeout. - Default is 7 days. + Default is 30 days.
