arc-deltaperiod-config-plugin creates a list of formatted dates to easily calculate data processing periods.
Documentation
To use the plugin specify a return format, the lag and lead days and a variable name to return. This example will create a string like 2019-07-01,2019-07-02,2019-07-03,2019-07-04,2019-07-05,2019-07-06,2019-07-07,2019-07-08,2019-07-09,2019-07-10,2019-07-11,2019-07-12
. Optionally currentDate
can be specified in the same format as the formatter
to specify a deterministic date for testing.
This string can then be used with the glob
processing capabilities of Spark to read a subset of input files:
