TierSegmentUploadInitiate

public TierSegmentUploadInitiate(TopicIdPartition topicIdPartition,
                                 SegmentUploadInitiate metadata)

Method Detail

initialBufferSize

public static int initialBufferSize()

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

state

public TierObjectMetadata.State state()

Description copied from class: AbstractTierSegmentMetadata

The current state of the segment.

Specified by:

state in class AbstractTierSegmentMetadata

baseOffset

public long baseOffset()

endOffset

public long endOffset()

maxTimestamp

public long maxTimestamp()

size

public int size()

hasEpochState

public boolean hasEpochState()

hasAbortedTxns

public boolean hasAbortedTxns()

hasProducerState

public boolean hasProducerState()

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

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

opaqueData

public TierObjectStore.OpaqueData opaqueData()

payloadBuffer

public ByteBuffer payloadBuffer()

Specified by:

payloadBuffer in class AbstractTierMetadata

Returns:

backing payload buffer for this metadata.

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

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractTierMetadata

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractTierMetadata
