Introduction

A separate database plugin to support Snowflake-specific features and configurations.

Use-Case

• Users can choose and install Snowflake source and sink plugins.
• Users should see Snowflake logo on plugin configuration page for better experience.
• Users should get relevant information from the tool tip:
  
  • The tool tip should describe accurately what each field is used for.
• Users should not have to specify any redundant configuration
• Users should get field level lineage for the source and sink that is being used.
• Reference documentation should be updated to account for the changes.
• The source code for Snowflake database plugin should be placed in repo under data-integrations org.
• The data pipeline using source and sink plugins should run on both mapreduce and spark engines.

User Stories

Snowflake Overview

Snowflake is an analytic data warehouse provided as Software-as-a-Service (SaaS). Snowflake provides a data warehouse that is faster, easier to use, and far more flexible than traditional data warehouse offerings.

Snowflake’s data warehouse is not built on an existing database or “big data” software platform such as Hadoop. The Snowflake data warehouse uses a new SQL database engine with a unique architecture designed for the cloud. To the user, Snowflake has many similarities to other enterprise data warehouses, but also has additional functionality and unique capabilities.

Design Tips

JDBC Driver API Support: https://docs.snowflake.net/manuals/user-guide/jdbc-api.html

Loading Data into Snowflake: https://docs.snowflake.net/manuals/user-guide-data-load.html

Design

The suggestion is to create a new maven project in it's own repository.

Snowflake bulk API

Using JDBC for loading data has performance limitations. Snowflake provides bulk APIs for loading data: https://docs.snowflake.net/manuals/user-guide-data-load.html
