[Improvement] Add more sales data

[justinmclean]

I'd like to add more sales data but loading via SQL through Trino is slow. Is there a better way to load more data?

[justinmclean]

Perhaps something like this?

load data local inpath '/tmp/customers.csv' overwrite into table sales.customers; load data local inpath '/tmp/sales.csv' overwrite into table sales.sales;

customers.csv sales.csv
