Hello Community!
My name is Diego and I’m working as a system engineer in a GPS company from Chile.
We are using Cratedb at work with 2.8 billion Total records with a continuous insert of 400 rows per sec 24/7.
This is a big IOT-database and the engine is working good as expected, but we have a little problem.
When some query reaches the circuit breaker(or some other thing that I can’t view), the inserts goes down to 50 per second until I restart the nodes with systemctl restart crate. After I restart the engine the inserts goes to normal speed: 400/sec.
What can cause and how to fix the slow insert speed behavior without restart the cluster?
Specs:
8 CPU X 32RAM
HEAP: 16GB
Cloud: AWS
Cluster: 3 nodes
Cratedb: 4.1.1
Shards: 10, partitioned by month.
Total rows: 2.8 Billion
Thanks for advance.

Hola Diego, que tal todo!?
Sounds like you have setup a very interesting use case!
Sorry to hear that you run into this unexpected behaviour. Could you please share some `logs` of the circiut breaker that you mentioned (form all of the 3 nodes), and if possible the kind of `queries` and `crate.yml` you run in that context. Let’s see where we can go on from there.
In general it sounds like something else is going on, as a circuit breaker is nothing IMHO that would create such a behaviour.
regards,
Walter
