I want save data to elasticsearch by a json input, but when I created it I found that all my field type is string...
I try to format my data and it can achieve number and string two types' indices like this:
But c is an IP type here it is classified as string too... And I try to use mutate but find mutate can only support integer, float, string, and boolean convertion.
So is there a way to customize field type? Thanks
