I have used a timestamp the comes from Logstash looking like this:
In mappings I have set it as:
"format": "yyyy-MM-dd HH:mm:ss,SSSZ"
However in the alias/index, the timestamp appears a string type. I have a previous index in the alias with the timestamp set as a string, but I created a new index with the timestamp as a date type with the above format mentioned. My new index is working fine, but the new Date Format on the "timestamp" field does not seem to change?
