I have a requirement to clear the existing index data and load the data into the same index whenever we run the logstash config.

How can we achieve this through the config file ?

You are better off deleting the index and recreating it. That will need to be done externally.

Otherwise, create a new index and then use an alias to manage where it points to.

Cant we have the " delete index " ([https://www.elastic.co/guide/en/elasticsearch/guide/current/\_deleting\_an\_index.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/_deleting_an_index.html)) Api calls in the logstash config files?
