I am using logstash 5.1.1
I ported data from mysql using mysql input plugin to elasticsearch. When I run the pipeline, for the tinyint fields, logstash cannot convert it to integer automatically.
So I used mutation filter and convert to integer
mutate {
convert => {"record_impression" => "integer" }
}
