Use apoc.export.csv.query to append to an existing csv file

[thulasi_paladug]

the library overwrites the csv file and I need to append to the file.
wanted to know the options to append to the existing csv file using apoc.export.csv.query

Please create a github issue to add it as a config option. Then there probably needs to be an option too to leave headers off

Thank you for the reply, Michael. You mean to say... option needs to be set in neo4j.conf file to work this ?
Also I would like to know that is there a way to create/install triggers on the cluster without stopping and starting the cluster ?
