        Set the list of Keys to get associated items.
        参数:
        keys - The key attributes and values to get items from a table.
        抛出:
        IllegalArgumentException - if the list is empty.

      • setConsistentRead

        public void setConsistentRead​(boolean consistentRead)
        Set the type of the consistency of a read operation.The default value is false, representing that it is eventually consistent read. If the value is true, it is a strongly consistent read.
        参数:

        参数:
        consistentRead - The consistency of a read operation. The default value is false, representing that it is eventually consistent read. If the value is true, it is a strongly consistent read.
        返回:
