I have a problem about memory usage of elasticsearch. In my system, 60000 documents are written to the database per hour .
But memory usage is constantly increasing over time. I don't understand why it is always increasing. Elasticsearch container ram capacity is 10GB and heapsize 5GB for JVM . I suspect that caches are kept in memory, but I have not encountered an abnormal situation in elastic search configuration settings. I check this query: GET /_stats
After a certain period, memory usage of container becomes 100% and elasticsearch can't response any query.
I would be very pleased if you can help me.
