Dremio UI high latency

Hello everyone,

Has someone found issues with Dremio UI latency?

In our case, Dremio is being run on an EC2 cluster well configured to guarantee High Availability, with 2 coordinators (m5.2xlarge), one in production and the other standby, and 3 executors (r5d.2xlarge). The metadata store is located on a shared volume using EFS. On top of this cluster, we set up an application load balancer with 4 minutes timeout. Sometimes, Dremio UI takes a while to respond, resulting in a 504 error.


If you directly connect to the primary coordinator, do you still get a 504?
