I do not if it possible, but I couldn't find any information regarding the renaming of the fields based on the dictionary.
I would like to use Logstash to convert all the entry data to the 'standard' format for the further ElasticSearch storage.
Some entries can have the same logical fields, but the name of them can vary, e.g. one system can send a field 'Employee Name', the other 'EmpName' or 'EmployeeName'. So I would like to convert all these records to 'EmployeeName' field, that I have in my mapping in the ElasticSearch index.
I know there is a mutate rename field method. But it is not based on the dictionary. Is there a way to use the file like in the Translate method, as I can generate the file from the code?
