It will be useful to use this official benchmark tool to benchmark our server against redis. But we get an error while running the benchmark. After checking, it turned out the benchmark utility run the redis config get command before. So implement config get as expected by the benchmarking tool. Here are the commands sent by the benchmark tool.

worker 1 received a job
*3
$6
CONFIG
$3
GET
$4
save

*3
$6
CONFIG
$3
GET
$10
appendonly

Here is the response from our implementation:

➜  redisy git:(main) ✗ redis-benchmark -t ping -n 100000 -q
WARNING: Could not fetch server CONFIG
Error from server: wrong RESP frame type, needed another type here

The specs for the config get command can be found here https://redis.io/commands/config-get/
