redis-benchmark: Run with a specific script.

redis-benchmark

$ redis-benchmark -n ${100000} script load "${redis-call('set', 'foo', 'bar')}"

try on your machine

The command "redis-benchmark" is used to measure the performance of a Redis server by simulating a set of client operations. It is a utility provided by Redis.

The specific command you provided is:

redis-benchmark -n ${100000} script load "${redis-call('set', 'foo', 'bar')}"

This command invokes the redis-benchmark utility and performs the following actions:

-n ${100000}: Specifies the number of total requests to be made to the Redis server. In this case, it is set to 100,000 requests. ${100000} indicates that the number of requests is determined by the value of the environment variable "100000".
script load "${redis-call('set', 'foo', 'bar')}": This part of the command is used to load and execute a Lua script on the Redis server. The script being loaded is "${redis-call('set', 'foo', 'bar')}".
- redis-call('set', 'foo', 'bar'): This is a function call within the Lua script. It instructs Redis to execute the SET command, which sets the value of the key "foo" to "bar". The Lua script is enclosed within double quotes to pass it as an argument to the script load command.
- The purpose of using a Lua script is to perform a specific Redis command repeatedly for benchmarking purposes.

Overall, this command will execute the specified Lua script (SET command) 100,000 times against the Redis server specified in the redis-benchmark configuration and provide performance metrics based on the execution.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
