I have an xml file , and i want to parse it to logstash. The issue is that when i have a large xml file (1Go) , the memory crashes because , the logstash try to load the whole xml file in memory . Is there a way in logstash that recognize adding a specify size of data to memory , and after sending data to elasticsearch , the specified size of data will be deleted , and after that logstash loads the same next size of data to memory?

Thank for your help.
