Roman Gershman ab5031472e Small fixes 1. Remove CO::STALE modifier since it's not relevant for now. 2. Propertly wire CallFromScript function to be called from redis.call. 3. Define 3rd party lua dependency as part of dragonfly project. 4. Add ARGV/KEYS arrays to lua scripts		2022-02-24 14:11:51 +02:00

Dragonfly

A toy memory store that supports basic commands like SET and GET for both memcached and redis protocols. In addition, it supports redis PING command.

Demo features include:

High throughput reaching millions of QPS on a single node.
TLS support.
Pipelining mode.

Building from source

I've tested the build on Ubuntu 21.04+.

git clone --recursive https://github.com/romange/dragonfly
cd dragonfly && ./helio/blaze.sh -release
cd build-opt && ninja dragonfly

Running

./dragonfly --logtostderr

for more options, run ./dragonfly --help

In addition, we want to support efficient expiry (TTL) and cache eviction algorithms. We should implement basic memory management support. For Master/Slave replication we should design a distributed log format.

Also, I would omit keyspace notifications. For that I would like to deep dive and learn exact use-cases for this API.

Milestone Nymph

API 2,3,4 without cluster support, without modules, without memory inspection commands. Without support for keyspace notifications.

Design config support. ~140 commands overall...

Milestone Molt

API 5,6 - without cluster and modules. Streams support. ~80 commands overall.

Milestone Adult

TBD.
