Concise monthly summary for 2026-01 for apache/nifi, focusing on enhancements to the RecordPath DSL to expand in-pipeline data manipulation capabilities and data quality controls.

November 2025, tarantool/datafusion: Implemented named and default parameter support for CREATE FUNCTION in SQL, including validation for parameter styles, enforcing that non-default parameters precede default ones, and updates to handle function signatures and defaults in ScalarFunctionWrapper. This change enables flexible UDF definitions with named arguments while preserving backward compatibility and improving error messaging. Added comprehensive tests and updated SQL UDF examples; work closes #17887 and improves developer ergonomics and runtime reliability for SQL function definitions.

October 2025 (tarantool/datafusion) delivered a focused feature upgrade around ad-hoc analytics: added support for temporary views in DataFrameTableProvider and a new public API DataFrame::into_temporary_view to create transient tables without duplicating code. Provider logic updated to determine table_type, and a dedicated test (register_temporary_table) verifies the end-to-end behavior. This work strengthens interoperability with datafusion-python and closes the linked issue (Closes #18026) with changes aligned to PR #18158. Impact: enables lightweight, reusable transient views for analytical workflows, reduces boilerplate, and improves test coverage and reliability for temporary-views paths. Public-facing API change simplifies temporary table usage for developers. Commit reference: 0a650a0d27cab21591eccb85d048a1907fc75f14
