TESTING
Using Athena to create iceberg tables in s3Tables

CREATE TABLE `nyc`.daily_sales (
sale_date date, 
product_category string, 
sales_amount double)
PARTITIONED BY (month(sale_date))
TBLPROPERTIES ('table_type' = 'iceberg')

INSERT INTO daily_sales
VALUES
(DATE '2024-01-15', 'Laptop', 900.00),
(DATE '2024-01-15', 'Monitor', 250.00),
(DATE '2024-01-16', 'Laptop', 1350.00),
