App Engine provides a distributed in-memory data cache in front of the robust, persistent storage that you can use for certain transient tasks The Memcache API supports the JCache interface JCache is a draft standard that provides a map-like interface to the cached data store Through JCache you store objects of any type or class in key/value pairs This makes it very quick and simple to store and retrieve session data, query results, and subsets of data that will be reused throughout the application If you re running the same set of data-store queries multiple times in the same user s session, you should consider using the memory cache to speed the response time of the application For example, consider a web site where users are browsing for a phonebook-type service in their area. The three rows in the two result sets follow from the initial INSERT statements to populate the Classes and ClassGrades tables as well as from the UPDATE statement in the immediately preceding script The number of rows affected by the first SELECT statement is three The intervening UPDATE statement affects one row The second SELECT statement also affects three rows Notice the ClassTitle column value switches from Biographies of Jesus Christ to The Life of Jesus Christ between the first and second result sets This is a consequence of the UPDATE statement StudentID ----------1 2 2 ClassTitle --------------------------Learning SQL Server Express Learning SQL Server Express Biographies of Jesus Christ GradeLetter ----------C+ A+ A. vb.net qr code reader free C# .
