### What would you like to happen? Context / Problem I need a transform that applies conditional rules (IF/ELSE) to rows in a pipeline. It should evaluate one or more input columns and, when a condition matches, update the value of one or more target columns. Today this typically requires chaining multiple transforms, which becomes hard to maintain, audit, and evolve. Goal Create a declarative, rule-driven transform to update column values at runtime in a pipeline. Functional requirements Allow configuring an ordered list of rules. Each rule must include: Condition: a boolean expression using row columns (e.g., colA = 'X' OR colB = 'Y'). Actions: update 1..N columns with: a constant value, and/or the value of another column, and/or an expression (optional, if supported). Support rule application policy: FIRST_MATCH: apply the first matching rule and stop. ALL_MATCHES: apply all matching rules in order. Handle null values and basic type conversions (string/number/date) according to target columns. Provide clear configuration-time errors when a condition/action is invalid (e.g., missing column, type mismatch). ### Issue Priority Priority: 3 ### Issue Component Component: Transforms -- This is an automated message from the Apache Git Service.
