PushStatusStoreReader

public PushStatusStoreReader(com.linkedin.d2.balancer.D2Client d2Client,
 String clusterDiscoveryD2ServiceName,
 long heartbeatExpirationTimeInSeconds)

Method Details

getVersionStatus

public Map<CharSequence,Integer> getVersionStatus(String storeName,
 int version,
 Optional<String> incrementalPushVersion)

getPartitionStatus

public Map<CharSequence,Integer> getPartitionStatus(String storeName,
 int version,
 int partitionId,
 Optional<String> incrementalPushVersion)

getPartitionStatus

public Map<CharSequence,Integer> getPartitionStatus(String storeName,
 int version,
 int partitionId,
 Optional<String> incrementalPushVersion,
 Optional<String> incrementalPushPrefix)

getPartitionStatuses

public Map<Integer,Map<CharSequence,Integer>> getPartitionStatuses(String storeName,
 int storeVersion,
 String incrementalPushVersion,
 int numberOfPartitions)

Return statuses of all replicas belonging to partitions with partitionIds in the range [0 (inclusive), numberOfPartitions (exclusive)) {partitionId: {instance:status, instance:status,...},...}

getPartitionStatuses

public Map<Integer,Map<CharSequence,Integer>> getPartitionStatuses(String storeName,
 int storeVersion,
 String incrementalPushVersion,
 int numberOfPartitions,
 int batchGetLimit)
