Is it possible to use jdbc\_static to iterate over all fields of the event and replace the field names, perhaps with the mutate filter? I have jdbc\_static set up correctly, but I'm having trouble with the iteration over all event fields. It seems to insist that I know in advance the names of each event field, but I want to iterate over every field in the event and rename that field using the lookup in the table loaded by jdbc\_static.

Specifically, in the local\_lookups section of jdbc\_static, how to I set the parameters to something other than the value of a known field name?

Alternatively, is there a different way to rename all the fields of an event based on a lookup table in a database, without modifying the field values?

Thanks -  
Brad
