Hi, im working with fluentbit to export the logs from my k8s env, then to kafka, logstash and in the end to elasticearch, the massages are indexing inside ES but after a while they stop to index, i conf heap to 8G, but still the same. there is a way that i can make logstash work only on ram (without persistent volume)
Thanks !

Why do you think this will stop the issue at hand?
What version are you running?
What do the Logstash logs show?
