      Description

      The defaults for readwritesplit are slave_selection_criteria=LEAST_CURRENT_OPERATIONS and max_slave_connections=1. With these values, it is possible that only one slave server is used for all connections and all other slaves are idle.

      Either the slave_selection_criteria should be changed to LEAST_GLOBAL_CONNECTIONS or max_slave_connections to be set to 100%.
