TierPartitionForceRestore

public TierPartitionForceRestore(TopicIdPartition topicIdPartition,
                                 PartitionForceRestore metadata)

Method Detail

initialBufferSize

public static int initialBufferSize()

The initial buffer size to use when constructing the FlatBuffer message.

startOffset

public long startOffset()

endOffset

public long endOffset()

contentHash

public String contentHash()

version

public byte version()

restoreLogStartOffset

public boolean restoreLogStartOffset()

type

public TierRecordType type()

Specified by:

type in class AbstractTierMetadata

Returns:

byte ID for this metadata entry type.

topicIdPartition

public TopicIdPartition topicIdPartition()

Description copied from class: AbstractTierMetadata

Topic-partition corresponding to this tier metadata.

Specified by:

topicIdPartition in class AbstractTierMetadata

Returns:

topic partition

payloadBuffer

public ByteBuffer payloadBuffer()

Specified by:

payloadBuffer in class AbstractTierMetadata

Returns:

backing payload buffer for this metadata.

tierEpoch

public int tierEpoch()

Description copied from class: AbstractTierMetadata

tierEpoch for the tier metadata

Specified by:

tierEpoch in class AbstractTierMetadata

Returns:

tierEpoch

stateOffsetAndEpoch

public OffsetAndEpoch stateOffsetAndEpoch()

Description copied from class: AbstractTierMetadata

The lastMaterializedOffsetAndEpoch for the tier partition state at the time this metadata was generated. This is used to ensure that the metadata is intended to be applied to this state, and that it has not undergone a restore. This metadata may be successfully applied to a tier state with restoreOffsetAndEpoch <= stateOffsetAndEpoch. OffsetAndEpoch.EMPTY indicates that the metadata is an older version that does not contain this field, or that it may be applied without a check against restoreOffsetAndEpoch.

Specified by:

stateOffsetAndEpoch in class AbstractTierMetadata

Returns:

OffsetAndEpoch

messageId

public UUID messageId()

Description copied from class: AbstractTierMetadata

Get a unique id for this message. This is a unique fingerprint that identifies the message.

Specified by:

messageId in class AbstractTierMetadata

Returns:

the message id

toString

public String toString()

Overrides:

toString in class Object
