Properties

Some basic rules:

• Property names are akin to a full JSON path to locate a leaf in the JSON object
• The root namespace is datax.job
• Property names are all lowercase for known fields from the JSON config object, except cases from Map and Array
• Map case - e.g. the outputs is a Map of string to individual output config, in this case, put the string into the property name as part of the path
• Array case - e.g. the timeWindows is an Array of time window specs, in this case, extract the name as part of the path into property name
• When flatten Map/Array, change the plural words into singular term, e.g. change outputs to output, timeWindows to timewindow, etc.
