Test Data of Proxy Cluster DCS Redis 4.0 or 5.0 Instances

Test Environment

  • Redis instance specifications

    Redis 4.0 or 5.0 | 64 GB | 8 shards | Proxy Cluster

  • ECS flavors

    General computing-enhanced | c6.xlarge.2 | 4 vCPUs | 8 GB

  • Test tool

    Three ECSs are used for concurrent tests. The test tool is memtier_benchmark.

Test Command

memtier_benchmark --ratio= (1:0 and 0:1)-s {IP} -n {nreqs}  -c {connect_number}  -t 4 -d {datasize}

Reference values: -c {connect_number}: 1000; -n {nreqs}: 10,000,000; -d {datasize}: 32
