   Hi @joe-clickhouse,
   
   Thanks for taking the time to review the PR.
   
   I've made the requested changes and tested them locally as well.
   
   I had a couple of questions:
   
   1. Should we use Decimal instead of Float64? Is there a preference from a 
query performance or precision perspective?
   2. If the connected ClickHouse cluster has replication enabled, we'd need to 
use ReplicatedMergeTree instead of MergeTree. Should we handle that case as 
well?
   
   I was thinking of checking system.replicas or system.zookeeper to detect 
whether replication is enabled. However, that would require the ClickHouse user 
provided during database setup to have permissions to query those system 
tables. Does that seem like the right approach, or would you prefer a different 
way of handling it?
