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.
This command requires a keyspace. Ideally, you have also created a table, but it isn’t required.
DESCRIBE TABLE cycling.birthday_list;If the table exists, the output includes all settings for tables and other objects including the default settings. If you use this output to recreate a table in another environment, verify that the settings are compatible.
