hello everyone , is it recommended to use sharding to horizantally scale the clickhouse cluster over multiple nodes if data ingestion requirement in db can max reach to 7200gb that is retainable and to be queried to display metrics/traces or it will be better to keep clickhouse in single node with required storage , just want to anaylse the performance trade offs .

is it 7200gb per day or per hour?

no actually it is monthly estimated ingestion , per day ingestion is of around 250 gb .
but i m confused as i have no that much idea about clickhouse performance or any threshold till when the query performance is not bad .

Sharding introduces upto 20% latency increase compared to single machine. So you can afford single machine then go with with single machine or go with sharding.
