This section discusses the evaluation of the processing that is to be performed by the standard adaptors.
The processing to be performed by the standard adaptors includes data input and output, data editing, and sending and receiving of tuples. The following figure shows the flow of processing performed by the standard adaptors.
Figure 2-10 Flow of processing performed by the standard adaptors
With the standard adaptors, each of the data input and output, data editing, and tuple exchange processing elements is called a callback. Callback processing is defined in each CB definition in the adaptor configuration definition file, one of the adaptor definition files.
For the callback processing performed by the standard adaptors, you must evaluate the nature of the processing that is to be performed as data input and output and data editing processing. Your evaluation will include how data is to be input, output, and edited in accordance with the purpose of stream data summary analysis in your system.
