Enum Constant Summary

Enum Constants

Enum Constant	Description
BATCH_WRITE_LOSES	Incoming data from Batch push should always be overwritten by real-time updates.
USE_PER_RECORD_LOGICAL_TIMESTAMP	Per-record replication metadata is provided by the push job and stored for each key, enabling full conflict resolution granularity on a per field basis, just like when merging concurrent update operations.
USE_START_OF_PUSH_TIMESTAMP	Start-Of-Push Control message's timestamp should be treated as the last update replication timestamp for all batch records, and hybrid writes wins only when their own logicalTimestamp are higher.

Method Summary

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

Method Details

values

public static BatchConflictResolutionPolicy[] 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
