Web-based management of the cached object allows us to monitor the data that is in memory.
For the reports-to chain cache, it shows data for an employee??™s reporting structure. It also
allows an administrator to manage the data in memory (create, update, delete), commit
those changes to the file system or database, and reload the cache, if necessary. Providing
administrators with management capabilities to key subsystem components removes the
specialists from having to perform more risky manual tasks in support of an application. It
also allows the application to appear more responsive by supporting more real-time management
instead of code changes or manual application restarts.
By using strategic caching, BluePages was able to see a reduction of 800 milliseconds in
response time. Approximately 750 milliseconds were due to the reports-to chain cache and
~50 milliseconds were associated with database calls. Currently the same page delivers a
70ms server-side response time.
Another situation in which dynamic data caching plays an important role is the design of
service implementations.
