Snowflake separates compute and storage, so it is typical to have a dedicated compute cluster (virtual warehouse) to handle data ingestion into Snowflake (if you do not use Snowpipe).
Like reporting and Ad-hoc SQL, data ingestion has some specifics. Usually there are many tables (data sources) that have own schedule (daily, hourly, every 5, 10, 15 minutes etc.) for periodic data transfer. ETL processes can be overlapped, and can have spikes followed by idle time and so on.
