Queries all the devices of a product.

Limits

  • Each Alibaba Cloud account can run a maximum of 50 queries per second (QPS).
    Note RAM users of an Alibaba Cloud account share the quota of the account.

  • When the value of the CurrentPage parameter multiplied by the value of the PageSize parameter equals a value greater than or equal to 100000, the QPS of this operation decreases.

    In this case, each Alibaba Cloud account can run a maximum of 2 QPS.
