dojodis 🍤

[dojodis] is an experimental high-performance [Redis][redis] clone written [Scala ZIO][zio].

Supported Commands

dojodis server supports the following [Redis commands][commands] !: [get], [set], [exists], [incr], [incrby], [ping], [del], [keys]

Development

sbt run

redis-cli -p 6666 set my_name "Oto Brglez"
redis-cli -p 6666 get my_name
cat test.txt | redis-cli -h 127.0.0.1 -p 6666

Silly benchmark

Although this is considered to be a very experimental project I was really tempted to make it compliant with [redis-benchmark] to see how it will perform.

![Simple dojodis vs. Redis v7 benchmark]!(redis-7_vs_dojodis.png)

Benchmark was ran against Redis server v=7.0.0 sha=00000000:0 malloc=libc bits=64 build=efafb97113670c08 and here are the results for the common test suite. Raw data can be found here.

redis-benchmark -h 127.0.0.1 -p 6666 -t get,set,incr,incrby,del -n 100000 -c 4 --csv
