Description

Usage-case...

One wants it to start on the same specific date so that each day, it processes one more data set than the last day (the datasets are daily). Something like the following

<input-events>
<data-in name="event_input_path_format1" dataset="EVENT_INPUT_FORMAT1">
<start-instance>${coord:absolute(2013-03-15T00:00Z)}</start-instance>
<end-instance>$

{coord:current(-1)}

</end-instance>
</data-in>
<data-in name="event_input_path_format2" dataset="EVENT_INPUT_FORMAT2">
<start-instance>${coord:absolute(2013-03-15T00:00Z)}</start-instance>
<end-instance>$

{coord:current(-1)}

</end-instance>
</data-in>
</input-events>
---------------------------------

Specifying a fixed date as the start instance is useful if processing needs to process all dataset instances from a specific instance to the current instance.
