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.

Commands that I prefer not implement before launch:
- PUNSUBSCRIBE
- PSUBSCRIBE And 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 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.
