"This implementation is based on the [Source Code: StdOutCallbackHandler](https://api.python.langchain.com/en/stable/_modules/langchain_core/callbacks/stdout.html#StdOutCallbackHandler).\n",
"\n",
"The callback handler is initialized with a Snowpark Session, which has been pre-defined with the database, schema, role & warehouse. It is assumed that the role has the ability to create table and insert records into the table, for the respective database and schema. The log by default will create the table __langchain_callback_log__ and store the captured logs.\n",
"\n",
"For this demo, I am using the default Snowflake table. While this is functional but it would be a costlier option as row inserts is not recommended on these tables. I would recommend usage of Snowflake Unistore tables as these are more suitable for row based inserts."

"Summary: A snowflake is a single ice crystal that has achieved a sufficient size, and may have amalgamated with others, which falls through the Earth's atmosphere as snow. Each flake nucleates around a tiny particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants. The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate, and rime. Snow appears white in color despite being made of clear ice. This is due to diffuse reflection of the whole spectrum of light by the small crystal facets of the snowflakes.\n",

It was founded in July 2012 and was publicly launched in October 2014 after two years in stealth mode.The firm offers a cloud-based data storage and analytics service, generally termed \"data-as-a-service\". It allows corporate users to store and analyze data using cloud-based hardware and software. Snowflake services main features are separation of storage and compute, on-the-fly scalable compute, data sharing, data cloning, and third-party tools support in order to scale with its enterprise customers. It has run on Amazon S3 since 2014, on Microsoft Azure since 2018 and on the Google Cloud Platform since 2019. The company was ranked first on the Forbes Cloud 100 in 2019. The company's initial public offering raised $3.4 billion in September 2020, one of the largest software IPOs in history.\n",

Each flake nucleates around a tiny particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants. The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate, and rime. Snow appears white in color despite being made of clear ice.

The first stage is an equilateral triangle, and each successive stage is formed by adding outward bends to each side of the previous stage, making smaller equilateral triangles. The areas enclosed by the successive stages in the construction of the snowflake converge to \\n \\n \\n \\n \\n \\n \\n 8\\n 5\\n \\n \\n \\n \\n \\n {\\\\displaystyle {\\\\tfrac {8}{5}}}\\n times the area of the original triangle, while the perimeters of the successive stages increase without bound.
