redis-benchmark:tldr:9943b
The command redis-benchmark -n ${1000000} -t ${set,get} -P ${16}
is used to run benchmark tests on a Redis server.
Here's a breakdown of the command:
-
redis-benchmark
: This is the command line utility provided by Redis for benchmarking purposes. It measures the performance of a Redis server by executing various commands and operations. -
-n ${1000000}
: This option specifies the total number of requests to be made during the benchmark test. In this case, it is set to 1,000,000. This means that Redis will execute 1 million operations as part of the benchmark. -
-t ${set,get}
: This option specifies the type of commands that will be executed during the benchmark. The${set,get}
value indicates that both SET and GET commands will be benchmarked. SET is used to set a key-value pair in Redis, and GET is used to retrieve the value associated with a given key. -
-P ${16}
: This option specifies the number of pipelines to be used during the benchmark. A pipeline is a way to send multiple commands to the Redis server in a single network round-trip, improving the overall performance. In this case, it is set to 16, meaning that Redis will use 16 concurrent pipelines for executing the commands.
Overall, this command will run a benchmark test on a Redis server, executing 1 million SET and GET commands with 16 pipelines, and measure the performance metrics such as throughput (requests per second) and latency.
