Method Details

seekToTimestamps

public CompletableFuture<Void> seekToTimestamps(Map<Integer,Long> timestamps)

Description copied from interface: SeekableDaVinciClient

Seek to the specified timestamps for partitions and corresponding timestamps in the map.

Specified by:

seekToTimestamps in interface SeekableDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

Overrides:

seekToTimestamps in class AvroGenericDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

seekToTimestamp

public CompletableFuture<Void> seekToTimestamp(Long timestamp)

Description copied from interface: SeekableDaVinciClient

Seek to the specified timestamp for all subscribed partitions.

Specified by:

seekToTimestamp in interface SeekableDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

seekToBeginningOfPush

public CompletableFuture<Void> seekToBeginningOfPush(Set<Integer> partitions)

Description copied from interface: SeekableDaVinciClient

Seek to the begining of the push, for the specified partitions. Same as unsubscribe and subscribe.

Specified by:

seekToBeginningOfPush in interface SeekableDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

Returns:

seekToCheckpoint

public CompletableFuture<Void> seekToCheckpoint(Set<VeniceChangeCoordinate> checkpoints)

Description copied from interface: SeekableDaVinciClient

Seek the provided checkpoints for the specified partitions. Note about checkpoints: Checkpoints have the following properties and should be considered: - Checkpoints are NOT comparable or valid across partitions. - Checkpoints are NOT comparable or valid across regions - Checkpoints are NOT comparable across store versions - It is not possible to determine the number of events between two checkpoints - It is possible that a checkpoint is no longer on retention. In such case, we will return an exception to the caller.

Specified by:

seekToCheckpoint in interface SeekableDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

Overrides:

seekToCheckpoint in class AvroGenericDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

Returns:

a future which completes when seek has completed for all partitions

seekToTail

public CompletableFuture<Void> seekToTail()

Description copied from interface: SeekableDaVinciClient

Seek to the end of the last push for all subscribed partitions.

Specified by:

seekToTail in interface SeekableDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

Returns:

a future which completes when the operation has succeeded for all partitions.

seekToTail

public CompletableFuture<Void> seekToTail(Set<Integer> partitions)

Description copied from interface: SeekableDaVinciClient

Seek to the end of the last push for the specified partitions.

Specified by:

seekToTail in interface SeekableDaVinciClient<K,V extends org.apache.avro.specific.SpecificRecord>

Parameters:

partitions - the set of partitions to seek with

Returns:

a future which completes when the operation has succeeded for all partitions.
