• Part of [EPIC] Complete datafusion-spark Spark Compatible Functions #15914

Given the importance of Apache Spark in the analytics ecosystem, many users of DataFusion are interested in Spark compatible functions. We are in the process of adding a Spark compatible function library in the datafusion-spark crate in DataFusion: https://github.com/apache/datafusion/tree/main/datafusion/spark

This ticket is part of a series of ticket to implement those functions in DataFusion.

Describe the solution you'd like

Implement the function listed above in the datafusion-spark crate

Describe alternatives you've considered

1. Find the relevant test file https://github.com/apache/datafusion/blob/main/datafusion/sqllogictest/test_files/spark/datetime/next_day.slt
2. Add the function implementation (copy/paste from sail https://github.com/lakehq/sail/blob/main/crates/sail-plan/src/extension/function/datetime/spark_next_day.rs)
3. Add additional tests / documentation as needed. Instructions for testing are here and you can see some examples in the PRs linked below

Notes:

• You can run the tests via cargo test --test sqllogictests -- spark

Examples to follow:

• Here is an example PR that implements the factorial function and tests [datafusion-spark] Implement factorical function #16125

Reference Implementations

• ScalarFunction Implementations in Sail from: https://github.com/lakehq/sail/tree/main/crates/sail-plan/src/function
• Spark SQL documentation (example, here are the factorial docs)
• Implementations in Comet (note these do not have the ScalarFunction definitions): https://github.com/apache/datafusion-comet/blob/main/native/spark-expr
