# Golang Memcache Proxy Library

## Why this library?

This library helps to utilize memcached in a consistent and efficient way.

**Supporting features**:

* Deal with Consistency between Memcached and Database using the Lease Mechanism.

* Prevent thundering herd (a.k.a Cache Stampede).

* Efficient batching get to the underlining database, batching between lease gets

  and between retries for preventing thundering-herd.

* Memcached replication similar to MCRouter, without the need for an external proxy.

* Memory-weighted load-balancing for replication.

## Usage

* [Using a single memcached server and source from the database](examples/simple/main.go)

* [Using multiple memcached servers](examples/failover/main.go)
