redis-cluster-benchmark

Benchmark utils for Redis Cluster that is inspired by redis-benchmark.

• compiled on crystal-0.18.7
• binary download: https://github.com/maiha/redis-cluster-benchmark.cr/releases

Config

• See: bench.toml

[redis]
clusters = "127.0.0.1:7001,127.0.0.1:7002"  # at least one node
# password = "secret"

[bench]
requests = 100000  # number of requests for each commands
keyspace = 10000   # max number of key for `__rand_int__`
tests    = "set __rand_int__ __rand_int__"
after    = "set result/last __result__"
# after    = "rpush results __result__"
qps      = 5000
# debug = true

[report]
interval_sec = 1
verbose = true

Run

% redis-cluster-benchmark bench.toml
=== set __rand_int__ __rand_int__ ===
17:19:52 [5.0%] 5002/100000 (4989.3 qps)
17:19:53 [10.0%] 10003/100000 (4996.1 qps)
...
17:20:11 [95.1%] 95086/100000 (5000.9 qps)
17:20:12 done 100000 in 20.8 sec (0.0)
SET: 5820.68 rps (OK: 100000, KO: 0)

• Algthough we sent 100,000 requests, only 10,000 keys are created due to keyspace = 10000.

% rcm -u :7001 info count
893550 [127.0.0.1:7001]  cnt(3334)
bd4456 [127.0.0.1:7002]  cnt(3330)
87b981 [127.0.0.1:7003]  cnt(3336)

After Hook

• We can set after hook by after field in bench section.
• In above example, benchmark result has been set in redis via special keyword __result__.

% redis-cli -c -p 7001 get result/last
"1977.6 qps (OK:100000, KO:0) [02:53:26 +51s]"

• Of course, apending logs is good idea by rpush

after    = "rpush results __result__"

Roadmap

• [x] After Hook

0.4

• [ ] Reconnect after errors
• [ ] Multi Clients

0.5

• [ ] Connection Setting (use keep alive or not)
• [ ] Protocol Setting (use pipeline or not)
