Check a table
Using cqlsh, the DESCRIBE TABLE
command outputs the full details of a table, including all database objects the table contains.
Use the output from the DESCRIBE command to recreate the table and all its components.

The output includes all settings for tables and other objects including the default settings. When recreating a table in another environment, verify that the settings are compatible. |
