2.7 Efficient data processing using user functions
A user function is a program that defines a series of data operations (user processing) on specific data in a cache, such as totaling and analyzing data.
The user can first create a user function and place it on EADS servers, and then execute that user function by calling it from the EADS client.
A user function accesses only the data stored on the EADS server on which the user function was executed. Therefore, you can reduce communication overhead and achieve efficient data processing by using user functions instead of by using the EADS client.
Use Java to create user functions.
