I'm successfully importing SQL query data into ES via logstash - however, a numerical field is being processed as a string; so I have added a filter-mutate-convert into the pipeline to change the field to an integer; looking at the index mapping, this seems successful as it is now processed as "long" however, in the index pattern area, the field options now only give me the option of URL (in addition to the original string)?
The same is true of processing the field as a float; index pattern options for the field are limited to string and URL?
