Enum Constant Details

NO_OP_ON_FIELD

public static final WriteComputeOperation NO_OP_ON_FIELD

Mark to ignore the field. It's used for "partial put" and can be applied to any kind of schema. It's also the default for all record fields in the write compute schema.

PUT_NEW_FIELD

public static final WriteComputeOperation PUT_NEW_FIELD

Put a new value on an existing field. It's used for "partial put".

LIST_OPS

public static final WriteComputeOperation LIST_OPS

Perform list operations on top of the original array. It can be only applied to Avro array. Currently support: 1. setUnion: add elements into the original array, as if it was a sorted set. (e.g.: duplicates will be pruned.) 2. setDiff: remove elements from the original array, as if it was a sorted set.

MAP_OPS

public static final WriteComputeOperation MAP_OPS

Perform map operations on top of the original map. It can be only applied to Avro map. Currently support: 1. mapUnion: add new entries into the original map. It overrides the value if a key has already existed in the map. 2. mapDiff: remove entries from the original array.

Method Details

values

public static WriteComputeOperation[] 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 WriteComputeOperation 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

getName

public String getName()

getFieldOperationType

public static WriteComputeOperation getFieldOperationType(Object writeComputeFieldValue)

isPartialUpdateOp

public static boolean isPartialUpdateOp(org.apache.avro.generic.GenericRecord writeComputeRecord)
