to ArangoDB
I am trying arangodb with a small setup with 5 nodes in DCOS except master and bootstrap machine. With 3 coordinators in hand I wanted to make database highly available. So I installed haproxy load balancer with defalut settings. Load balancer seems working as I send any command using the load balancer it gives me the required results. My questions are:
1. Is there a way to find out(in case we send only one query through load balancer) which coordinator it is using hitting or using to execute that query?
2. After sometime suddenly load balancer says "services are unavailable". This happened while I was using a curl command for one of my foxx microservice app. I would like to mention at here that the curl command worked for many times, but suddenly it throned that error. If I use another load balancer (present on other machine started at same time as the earlier one) the things work again. If I kill this load balancer it is getting re-stagged on different machine. The concern is why it throws that error.
Please let me know if you need further details.
