Questions regarding cluster

[abhishekgahlot2]

Hi

The repo is great, I wanted to know some questions about the cluster.

Whats the default password of clickhouse?

Can i use only 1 or 2 zookeeper nodes, 3 seems high for 2 clickhouse nodes? Can i reduce down zookeeper nodes to small like t2.small?

I see only one clickhouse node is attached to load balancer. for eg if i have to connect to kafka which node do i connect to inside a vpc to able to connect to cluster?

Also does ClickHouseAdminClient need to be same size as clickhouse node

Thanks again for the help?

The default password of clickhouse is the same as the password of Grafana, which is stored in Amazon Secrets Manager. To retrieve the password, navigate to the AWS CloudFormation console, choose Outputs, and search for the DBPassword parameter.

All the other parameters like instance types and number of nodes, you can adjust base on your use case.
