Snowflake is a cloud-based data warehouse that offers scalable and secure storage and processing of structured and semi-structured data. Snowflake uses a shared-nothing architecture for parallel processing and offers native support for SQL as well as other programming languages such as Python, R, and Java Snowflake’s unique architecture consists of three key layers: - Database Storage - Query Processing - Cloud Services In Snowflake, they have done the decoupling of storage and compute. Virtual Warehouse: - A compute resource in Snowflake that processes queries and performs data loading and unloading. - It can be independently scaled up or down based on demand. - ...
RATIO_TO_REPORT If you have a table in which amounts are present and you want to calculate the percentage distribution of those amounts as below: + ----------+--------+----------------+ | STORE_ID | PROFIT | PERCENT_PROFIT | | ----------+--------+----------------| | 1 | 500 . 00 | 42 | | 2 | 250 . 00 | 21 | | 3 | 450 . 00 | 38 | | 4 | NULL | NULL | + ----------+--------+----------------+ MS-SQL Server Using the SUM function and OVER clause, you can achieve the above output as below: In Snowflake, we can use a similar approach as above. However, Snowflake has a different function RATIO_TO_REPORT : ...
