Polly.Contrib.DuplicateRequestCollapser.RedisDistributedLock is a Redis distributed lock for use with Polly.Contrib.DuplicateRequestCollapser
A distributed lock is great for the really big, expensive calculations or queries, etc. Something that can be measured in seconds time to get back is a great candidate for a distributed lock.
See RedisDistributedLockProvider.cs.
var lockTimeout = TimeSpan.FromSeconds(15.0); // wait 15 seconds and then give up trying to get the lock
var retryDelay = TimeSpan.FromMilliseconds(100.0); // wait 100 milliseconds in between each attempt to get the lock
void exceptionNotifier(Exception ex)
{
// log exception, etc...
}
// connectionMultiplexer comes from the StackExchange redis package.
var redisConnection = new RedisConnection(connectionMultiplexer);
var distributedLockOptions = new RedisDistributedLockProviderOptions(redisConnection,
lockTimeout, retryDelay, exceptionNotifier);
var distributedLock = new RedisDistributedLockProvider(options);
var collapserPolicy = RequestCollapserPolicy.Create(lockProvider: distributedLock);
// use the policy as normal, see https://github.com/Polly-Contrib/Polly.Contrib.DuplicateRequestCollapser/blob/master/README.md

This project has long file names, if the above does not work, try moving to a C:/Code folder or something to reduce folder char size.
