Modifying the Bandwidth of an Instance
Function
This API is used to temporarily increase the bandwidth of a DCS Redis 4.0 or later instance when traffic surges. The bandwidth is doubled after the expansion. The maximum bandwidth of a Proxy Cluster instance is 10,000 Mbit/s. If the bandwidth reaches this limit, it can no longer be increased. A temporarily increased bandwidth is valid for seven days. You can increase the bandwidth again one day after the previous increase expires. A maximum of three temporary increases are allowed for each instance.
