of items to be retrieved. Therefore, it's unlikely that any of the 15 threads will return empty result sets that could potentially represent wasted capacity. A query always uses 1 read capacity unit (RCU) or 1 write capacity unit (WCU), even if nothing is returned or no data is written...
Designing concurrent data structures should follow some basic rules. By separating the algorithms into two phases, we present guidelines for scalable data structures, with a analysis model based on the Amadal's law. To the best of our knowledge, we are the first to formalize a practical model...
Advantages of PersonDirectoryThe Face API also offers the LargePersonGroup structure, which has similar functionality but is limited to 1 million identities. The PersonDirectory structure can scale up to 20 million identities.Another difference between PersonDirectory and previous data structures is that...
data bindings which are documented in the sections, generating an import or export. In many cases, these standard bindings will be sufficient but in some cases you may want to write your own custom data binding to suit the needs of a particular application. In this section, we show you ...
Throughout this book we will build a couple of applications that load and retrieve inventory data from DB databases. While we are not yet ready to begin reading from or writing to our databases, we can at least create some important structures and functions that we will use to manage our ...
