Enum Constant Summary

Enum Constants

Enum Constant	Description
NO	The expression cannot be pushed to the source and must remain in FilterExec.
RECHECK	The expression can be pushed for efficiency (e.g., partition pruning), but must also remain in FilterExec for correctness.
YES	The expression can be fully pushed to the source and removed from FilterExec.

Method Summary

Modifier and Type	Method	Description
static FilterPushdownSupport.Pushability	valueOf(String name)	Returns the enum constant of this class with the specified name.
static FilterPushdownSupport.Pushability[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

YES

public static final FilterPushdownSupport.Pushability YES

The expression can be fully pushed to the source and removed from FilterExec. The source guarantees correct evaluation.

NO

public static final FilterPushdownSupport.Pushability NO

The expression cannot be pushed to the source and must remain in FilterExec.

RECHECK

public static final FilterPushdownSupport.Pushability RECHECK

The expression can be pushed for efficiency (e.g., partition pruning), but must also remain in FilterExec for correctness.

This is useful when the source can use the filter for optimization (like skipping files) but cannot guarantee exact semantics.

Method Details

values

public static FilterPushdownSupport.Pushability[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static FilterPushdownSupport.Pushability valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
