The [RedisTransactions] interface implemented by ServiceStack's C# Redis Client.

Redis transactions

Redis transaction interface provides useful overloads that let you Queue-up any [IRedisClient] operation within a single transaction. The API provides support for a callback so you also have access to any return values returned as part of the transaction as well.

Usage

Below is a simple example showing how to access, use and commit the transaction.

int callbackResult;
using (var trans = redis.CreateTransaction())
{
  trans.QueueCommand(r => r.Increment("key"));  
  trans.QueueCommand(r => r.Increment("key"), i => callbackResult = i);  

  trans.Commit();
}

For a strongly-typed transaction that operates on complex POCO types see [IRedisTypedTransaction IRedisTypedTransaction].
