Sequel Deprecation warning

Elastic Stack Logstash
1

Hi all,

Have recently upgraded logstash to 5.3.2 and I'm now getting this warning:

SEQUEL DEPRECATION WARNING: Database#identifier_output_method= is deprecated and will be removed in Sequel 5.  Explicitly load the identifier_mangling extension if you would like to use this.
/usr/share/logstash/vendor/bundle/jruby/1.9/gems/sequel-4.45.0/lib/sequel/extensions/_deprecated_identifier_mangling.rb:27:in `identifier_output_method='
/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-jdbc-4.1.3/lib/logstash/plugin_mixins/jdbc.rb:181:in `prepare_jdbc_connection'

/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:207:in `run'

My input looks like this:

input {
  jdbc {
    jdbc_driver_library => "/etc/elasticsearch-jdbc/lib/ojdbc7.jar"
    jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
    jdbc_connection_string => "${DB_STRING}"
    jdbc_user => "${DB_USER}"
    jdbc_password => "${DB_PASSWORD}"
    jdbc_fetch_size => 1000
    statement_filepath => "${ES_SQL}"
    parameters => { "update_date" => "${LAST_UPDATE}" }
    lowercase_column_names => false
  }
}

I have a feeling it's something to do with lowercase_column_names => false but I'm not sure how to fix it. Any suggestions?

Many thanks,
Dave
