FetchAs Setting
This setting applies to input cards only. It dictates how the adapter retrieves the
input data. By default, this setting is Integral. This means that all of the input
data is retrieved once from the source.
Setting this parameter to Burst means that the adapter will retrieve the input
data in increments specified in the FetchUnit parameter. The units of data
correspond to the highest-level repeating object in the type tree. For example, a
payroll file contains 105 records. Using Burst mode with the FetchUnit
parameter set to 10, data will be sent in 11 “chunks”. The first ten chunks will
contain ten records each with the eleventh chunk containing the remaining five
records.
Despite the fact that bursts process some of the map data and multiple sets of
outputs are built, transactional integrity is not sacrificed. If desired, the Scope
card setting can be set to Map to prevent any changes from being committed until
all bursts have finished successfully.
