To access a DCS Memcached instance, you must use an ECS that is in the same VPC as the DCS instance. In the application development and debugging phase, you can also use an SSH agent to access DCS Memcached instances in the local environment.
The migration task uses a tenant IP address (Migration ECS displayed on the Basic Information page of the task). If the target Redis has an IP whitelist, this IP address must be added to the whitelist.

Ranking with DCS Overview Ranking is a function commonly used on web pages and apps. It is implemented by listing key-values in descending order. However, a huge number of concurrent operation and query requests can result in a performance bottleneck, significantly increasing latency
DCS Metrics Introduction This section describes DCS metrics reported to Cloud Eye as well as their namespaces and dimensions. You can use the Cloud Eye console or call APIs to query the DCS metrics and alarms. Table 1 compares instance metrics. Table 1 Monitoring dimensions for different
