Use ListTables with an Amazon SDK or CLI - Amazon Keyspaces (for Apache Cassandra)
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Use ListTables with an Amazon SDK or CLI

The following code examples show how to use ListTables.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:
