I am trying to create a csv file by using the output csv in logstash. How can I insert the header only once at the very beginning? my data: ```auto es_field1 es_field2 es_field3 1 2 3 4 5 6 7 8 9 ``` logstash config: ```auto output { path => "/my/path/to/csv" csv_options => { "write_headers" => true "hearders" => "a,b,c" } fields => ["es_field1", "es_field", "es_field"] } ``` result: ```auto a b c 1 2 3 a b c 4 5 6 a b c 7 8 9 ``` Headers are inserted for each row. How can I insert the header only once at the very beginning? ---
