Snowpark is a library for querying and processing data at scale in Snowflake. Our teams use it for writing manageable code for interacting with data residing in Snowflake — it's akin to writing Spark code but for Snowflake. Ultimately, it's an engine that translates code into SQL that Snowflake understands. You can build applications that process data in Snowflake without moving data to the system where your application code runs. One drawback: unit testing support is suboptimal; our teams compensate for that by writing other types of tests.
