We have a 3 nodes (8 cores - 64 GB RAM each node) cluster in AWS Cloud. Our use case is an IOT platform and our data ingestion rate is about 350 insertions/sec. With a data retention window of about 6 months.
CRATE_HEAP_SIZE = 30.5 GB
We are currently getting nodes disconnections every 30 minutes or less. The node completely crashes, restart and a new master node is elected. This happens all day.
Thanks in advance
