A multi-threaded, TCP, key-value store inspired by Redis implemented in Haskell.
Note: This is a learning exercise.
You can read the introductory blog post.
$ git clone git://github.com/honza/redish.git
$ cd redish
$ stack build
$ stack exec Redish
Redish implements the Redis protocol. It currently only supports the get and set operations.
$ redis-cli -p 7777
127.0.0.1:7777> set name honza
OK
127.0.0.1:7777> get name
"honza"
BSD, short and sweet.
I'm on Ubuntu (19.04), just built the project like in the article, but when I want to test the performance I get the following:
➜ ~ time redis-cli -p 7777 -r 10000 get name
"name"
Error: Connection reset by peer
redis-cli -p 7777 -r 10000 get name 0,00s user 0,00s system 0% cpu 0,323 total
After one request the connection seems to be terminated. Even with a delay (with -i 1) the same happens.

If I omit this line, everything still seems to work. Why is it necessary?
