Running Multithreaded Redis using KeyDB and Dynomite

Keys is the default oss standard for K/V store for many use cases and solutions. When you need run low latency, high throughput IN Memory Persistence - Dynomite is your solution. I always wanted to have multi-thread support in redis like Memcached has. Now someone made it and call it KeyDB. The best thing is the fact that this is done supporting the redis RESP protocol, so all your tools, scripts and code using redis protocol directly still works. Another killer feature in KeyDB is the support for FLASH storage, only available on Redis Enterprise. KeyDB also supports backup to S3. For this post, I will show how to build and run KeyDB which is dead simple and also how to use it with Dynomite like it was Redis.





KeyDB Benchmarks

As you can see on the KeyDB benchmarks, KeyDB does 1.5x less latency and 50% more throughput. These numbers are pretty impressive. The best part is the fact that is all transparent.

Running KeyDB

Download and Install

git clone https://github.com/diegopacheco/KeyDB.git
cd KeyDB
make
./keydb-server

using with redis-cli

echo "set x 10" | redis-cli
echo "get x" | redis-cli

Running KeyDB with Dynomite

Donwload and Install Dynomite

#
# Install Dynomite
#
sudo yum install git -y
sudo yum install -y autoconf automake
sudo yum install -y libtool
sudo yum install -y openssl-devel
git clone https://github.com/Netflix/dynomite.git
cd dynomite
autoreconf -fvi
./configure --enable-debug=log
make
src/dynomite -h

cd ~/dynomite
touch keydb_as_redis_single.yml

echo "
dyn_o_mite:
  dyn_listen: 127.0.0.1:8101
  data_store: 0
  listen: 127.0.0.1:8102
  dyn_seed_provider: simple_provider
  servers:
  - 127.0.0.1:6379:1
  tokens: 437425602
" >> keydb_as_redis_single.yml

Download and install redis(only for the redis-cli)

#
# Install Redis
#

# YUM
sudo apt install redis-server

# Ubuntu
sudo yum install redis

#
# Stop Redis Server
#
sudo service redis stop

Download and install KeyDB

#
# Build and un KeyDB
#
git clone https://github.com/diegopacheco/KeyDB.git
cd KeyDB
make
./keydb-server

Run Doynomite

#
# Run Dynomite (other tab)
#
src/dynomite -c keydb_as_redis_single.yml

Access via redis-cli

echo "set x 10" | redis-cli -p 8102
echo "get x" | redis-cli -p 8102

Having fun with Zig Language

Image
Zig is a general-purpose language created in 2016 by Andrew Kelly .  Zig aims to fix the issues C language has while being pragmatic and simple at the same time. Zig really shines as being simple by not having any hidden control flows, not having hidden memory allocations, no pre-processors, and no macros. Basically, it's one language and one language only. Since pre-processors and macros can get really complex and become their own universe. Sure it's not the Zig Philosophy.  Zig Compiler(Zig cc) also is a C compiler, and the interoperability from C to Zig is very good. Clearly, we can see influence from other languages like Go and Rust; however, Zig is pretty unique and different from Go and Rust.  Zig is fast. Zig is perfect for system programming. I bet we will see a lot of solutions being built in Zig. As a languages aficionado, I like to learn at least one language per year and sometimes more; Zig was my 2021 pick, did not regret it. Even if you dont use all language...

C Unit Testing with Check

Image
When I start on IT, several years ago(+15), C was the first language that I learned. But was not the first language I mastered and deployed in production which was...surprisingly Visual Basic 6.0. However, when I learned C or any language back on that old and arcane time noddy was into testing. However now is impossible to work professionally in any language without tests. C is a low-level language but still kicks ass and has several interesting libs/frameworks. People use to fear C a lot because of lack of syntactical sugar but once you get used to it is not that hard at all. Today I want to show how you can do Unit Testing with C. I will not show how to do Unit Testing with C++ but with C ANSI actually. We will be using Check a unit test lib for C ANSI.

Cool Retro Terminal

Image
I often don't blog about this kind of stuff. Yesterday I friend of mine showed me this awesome project called  cool-retro-term . When you work with Cloud Computing and DevOps Engineering you spend lots of time on the black screen testing things on the cloud.  When I saw this project I got very excited because it brings some nostalgy back to my life. To be 100% clearI'm not that old as my friend :-) However I share his joy into this retro terminals. This also reminds me some old games like Fallout 1 . I just this is pure fun so I'm sharing here with you guys some screenshots and also how to run on Gnome Ubuntu 17.04.
