Usage notes

  • No read/write operation can be immediately performed on a table after it is created. Typically, you can perform read/write operations on a new table one minute after it is created.

  • A single instance can contain up to 64 tables. If you must raise the upper limit of the table quantity for a single instance, submit a ticket.
