<p>I was looking around for a lock free thread safe hash map implementation but couldnt seem to find one. Is there something similar to Java ConcurrentHashMap that uses CAS instead existing out there?</p>
<p>The other thing I was looking around but couldnt seem to find is an optimistic read type of lock similar to:
<a href="https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/locks/StampedLock.html">https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/locks/StampedLock.html</a>
It tends to perform much better than ReadWrite lock for some of my use cases in Java, so I was wondering how it would look like in Go.</p>
<p>if you've seen such packages flying around on github please share.</p>
