Hi ! ,  
I have question about streaming events to elastic search. For example say we have a file access.log which is continuously changes and in the logstash we have defined this file as an input.  
After I run logstash, it ingested access,log to the elasticsearch. Now if the file is keep updating can logstash keep looking at the access log for additional data ? what if logstash is being killed after ingestion and then if we restart logstash, it it going to pick up from where it stopped ?? How is this works ?

Yes, that's the default behavior.

Yes, see [File input plugin | Logstash Reference [8.11] | Elastic](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-file.html#_tracking_of_current_position_in_watched_files).
