Failure mechanism in logstash

[snazzypramod]

Hi Folks,

I am trying to push data from oracle to ES and I am able to do that as well. My problem when I am pushing those data and that time my ES goes down. I am using last_run_metadata_path property to update my last fetched value. My ES is down but still logstash is able to update last_run_metadata_path file.
Suppose after 10 minutes, when ES will up logstash is able to import data from oracle to ES. It will import all new data.
How i will import all those data who newly added when ES is down.

OS: window 10 enterprise
Logstash: 7.2.0
conf file.
