Redis 4.0 and 5.0 Instance Specifications

This section describes DCS Redis 4.0 and 5.0 instance specifications, including the total memory, available memory, maximum number of connections allowed, maximum/assured bandwidth, and reference performance.

The following metrics are related to the instance specifications:

  • Used memory: You can check the memory usage of an instance by viewing the Memory Usage and Used Memory metrics.
  • Maximum connections: The maximum number of connections allowed is the maximum number of clients that can be connected to an instance. To check the number of connections to an instance, view the Connected Clients metric.
  • QPS represents queries per second, which is the number of commands processed per second.
  • Bandwidth: You can view the Flow Control Times metric to check whether the bandwidth has exceeded the limit.

DCS Redis 4.0 and 5.0 instances are available in single-node, master/standby, and Redis Cluster types.
