Synthetic Memcached Proxy Build Status

Memcached fake, benchmarking proxy. This is designed to be a somewhat realistic synthetic middleware program in a distributed system. It functions as a kind of memcached proxy.

This implements the architecture of memcached, so a fairly high-performance network service for request/response style workloads. Multi-threaded with whole connections as the unit of distribution for load-balancing. Connections are round-robbin'd to threads and once assigned, are stuck.

No load-balancing or QoS after that.

Code is largely taken from memcached itself but cleaned up a lot.


The code is simple enough that we just use a single make file, no autotools or other complications. We do call pkg-config to find libraries and expect you to have gsl and libevent installed.


Should be it!

Memcached protocl support

This service connects to a collection of memcached backends.

Implemented commands:

  • GET -- just respond with a fixed value to every single key. Will send an RPC to every memcached backend and only respond to the get once all RPC's are completed.
  • SET -- parses command and returns ok but doesn't actually store data. (no backend involvement).

Other commands could be added easily but aren't needed for what I want.

Get involved!

We are happy to receive bug reports, fixes, documentation enhancements, and other improvements.

Please report bugs via the github issue tracker.

Master git repository:

  • git clone git://github.com/dterei/synthetic-memcached.git
