Fields§

§supported_variable_evaluation_mode: Option<Vec<DialectSupportedExecutionBehaviorSupportedVariableEvaluationModeItem>>

Supported execution context variable evaluation modes: * PER_PLAN: Variables are evaluated once per Substrait plan execution. All records in a single plan execution will see the same values for execution context variables like current_date and current_timestamp.

  • PER_RECORD: Variables are evaluated once per record during execution. Each record may see different values for execution context variables if the execution context changes between records.
