public class PushStatusStoreWriter
extends java.lang.Object
implements java.lang.AutoCloseable

PushStatusStoreWriter is a helper class for Da Vinci to write PushStatus and heartbeat message into PushStatus store real-time topic. Heartbeat update is a normal Venice write. PushStatus update is via a map-merge of Write-Compute.

Constructor Detail

PushStatusStoreWriter

public PushStatusStoreWriter(VeniceWriterFactory writerFactory,
                             java.lang.String instanceName,
                             SchemaEntry valueSchemaEntry,
                             DerivedSchemaEntry updateSchemaEntry)

Method Detail

writeHeartbeat

public void writeHeartbeat(java.lang.String storeName)

writeHeartbeatForBootstrappingInstance

public void writeHeartbeatForBootstrappingInstance(java.lang.String storeName)

This function will write `-1` to indicate the node is bootstrapping and Controller should ignore all the reports from this instance.

Parameters:

storeName -

writeHeartbeat

public void writeHeartbeat(java.lang.String storeName,
                           long heartbeat)

writePushStatus

public void writePushStatus(java.lang.String storeName,
                            int version,
                            int partitionId,
                            ExecutionStatus status,
                            java.util.Optional<java.lang.String> incrementalPushVersion)

writePushStatus

public void writePushStatus(java.lang.String storeName,
                            int version,
                            int partitionId,
                            ExecutionStatus status,
                            java.util.Optional<java.lang.String> incrementalPushVersion,
                            java.util.Optional<java.lang.String> incrementalPushPrefix)

writeVersionLevelPushStatus

public void writeVersionLevelPushStatus(java.lang.String storeName,
                                        int version,
                                        ExecutionStatus status,
                                        java.util.Set<java.lang.Integer> partitionIds)

This only works for "batch push" status update. Write one single push status for all partitions on this node, which assumes that all partitions are on the same state. The key only contains version number.

addToSupposedlyOngoingIncrementalPushVersions

public void addToSupposedlyOngoingIncrementalPushVersions(java.lang.String storeName,
                                                          int storeVersion,
                                                          java.lang.String incrementalPushVersion,
                                                          ExecutionStatus status)

removeFromSupposedlyOngoingIncrementalPushVersions

public void removeFromSupposedlyOngoingIncrementalPushVersions(java.lang.String storeName,
                                                               int storeVersion,
                                                               java.lang.String incrementalPushVersion)

deletePushStatus

public void deletePushStatus(java.lang.String storeName,
                             int version,
                             java.util.Optional<java.lang.String> incrementalPushVersion,
                             int partitionCount)

deletePartitionIncrementalPushStatus

public java.util.concurrent.Future<PubSubProduceResult> deletePartitionIncrementalPushStatus(java.lang.String storeName,
                                                                                             int version,
                                                                                             java.lang.String incrementalPushVersion,
                                                                                             int partitionId)
