Anyone else facing intermittence when querying? I'm getting
{
  "status": "success",
  "data": {
    "resultType": "matrix",
    "result": null
  }
}
and some successful queries

@Lucas Carlos Is this from queries in dashboards?

yes
@Pranay do you guys have a recommendation o clickhouse for high-availability? I found that if I have multiple replicas the data return as null

yes @Lucas Carlos, multiple replicas are not supported yet. If you enable replication, data will being ingested to just 1 shard and replica and the APIs will hit the correct shard with data in probabilistic way and hence you sometimes see data and sometimes see null
We are releasing distributed setup next week and replication in some time. I would recommend to get started with 1 shard and 1 replica

Thanks for the explanation
Please, let me know if we (SignalWire Inc.) can help to speed-up this process

sure....we are almost in testing phase of sharded setup. This would be non-breaking but replication will be breaking and would take sometime to release. Are you okay to try out a fresh signoz installation to enable both sharding and replication?
That way we don't need to wait for migration scripts

we've ~600 nodes on signoz at the moment
