May 2020

Feature Description Release date Supported region Reference
Dynamic bandwidth throttling ApsaraDB for Redis supports dynamic bandwidth throttling. If a shard of an instance almost runs out of bandwidth and the host where the instance is deployed has sufficient resources, bandwidth resources are automatically scaled out. If the host has insufficient resources or the shard reduces the bandwidth usage, bandwidth resources are automatically recycled.
Note The maximum bandwidth of ApsaraDB for Redis is 96 MB/s per shard. If the bandwidth exceeds this limit, the bandwidth is throttled.
2020-05-22 All regions None.
