I'm new to Databricks and am doing some basic data exploration using koalas.
When I connect into Databricks, I notice two primary tabs under DATA: DATABASE TABLES and DBFS. I was able to read csv files as koalas dataframes (ksdf=ks.read csv('/FileStore/tables/countryCodes.csv'), but I'm not sure how to read the tables listed under DATABASE TABLES as koalas dataframes. I'm guessing those are SQL tables because none of them have filename extensions.
