<p>The Blockstack API optionally uses memcached and pylibmc for scaling read-only
calls. If you want to enable this functionality then you should have memcached
running locally.</p>
<h3 id="memcached-on-debian--ubuntu">Memcached on Debian &amp; Ubuntu:</h3>
<div class="highlighter-rouge"><pre class="highlight"><code>$ sudo apt-get install -y python-dev libmemcached-dev zlib1g-dev
$ pip install pylibmc
</code></pre>
</div>
<h3 id="memcached-on-macos">Memcached on macOS:</h3>
<p>Easiest way to install memcached on macOS is by using <a href="https://brew.sh/">Homebrew</a>.</p>
<p>After installing Homebrew:</p>
<div class="highlighter-rouge"><pre class="highlight"><code>$ brew install memcached
$ brew install libmemcached
$ pip install pylibmc --install-option="--with-libmemcached=/usr/local/Cellar/libmemcached/1.0.18_1/"
</code></pre>
</div>
<p>After installing, you can start memcached and check if it’s running properly:</p>
<div class="highlighter-rouge"><pre class="highlight"><code>$ memcached -d
$ echo stats | nc localhost 11211
</code></pre>
</div>
<h3 id="memcached-on-heroku">Memcached on Heroku</h3>
<p>To deploy on Heroku:</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>heroku create
<span class="gp">$ </span>heroku addons:add memcachedcloud
<span class="gp">$ </span>git push heroku master
</code></pre>
