Creates a data table based on the specified schema.

Usage notes

  • After you create a data table, you cannot immediately perform read and write operations on the data table. In most cases, you can perform read/write operations on a table one minute after the table is created.
  • You can create up to 64 tables in a single instance. If you want to create more tables in a single instance, submit a ticket.
