Synchronous Reads, Asynchronous Writes
Data writes are often the bottleneck for application scalability. What if you moved all of your data writes over to an asynchronous style? How could other services and programs in your application take advantage of those broadcast writes to build optimized structures designed for high performance synchronous reads? Asynchronous writes enable you to build additional event driven intelligence seamlessly into your application. We'll cover in gory detail how to route all of your data writes throu... View More
