Method Detail

getReqStartVLSN

java.util.Map<oracle.kv.impl.topo.RepGroupId,com.sleepycat.je.utilint.VLSN> getReqStartVLSN()

Returns the requested start vlsn for each subscribed shard

Returns:

the requested start vlsn for each subscribed shard

getAckStartVLSN

java.util.Map<oracle.kv.impl.topo.RepGroupId,com.sleepycat.je.utilint.VLSN> getAckStartVLSN()

Returns the acknowledged start vlsn from NoSQL DB for each subscribed shard

Returns:

the acknowledged start vlsn from NoSQL DB for each subscribed shard

getLastCommitVLSN

java.util.Map<oracle.kv.impl.topo.RepGroupId,com.sleepycat.je.utilint.VLSN> getLastCommitVLSN()

Returns the last committed vlsn for each subscribed shard

Returns:

the last committed vlsn for each subscribed shard

getLastAbortVLSN

java.util.Map<oracle.kv.impl.topo.RepGroupId,com.sleepycat.je.utilint.VLSN> getLastAbortVLSN()

Returns the last aborted vlsn for each subscribed shard

Returns:

the last aborted vlsn for each subscribed shard

getLastMsgTimeStamp

java.util.Map<oracle.kv.impl.topo.RepGroupId,java.lang.Long> getLastMsgTimeStamp()

Returns the timestamp of last message from each subscribed shard

Returns:

the timestamp of last message from each subscribed shard

getTotalConsumedOps

long getTotalConsumedOps()

Returns the total number of stream operations that have been consumed by subscriber

Returns:

the total number of stream operations that have been consumed by subscriber

getTotalCommitTxns

long getTotalCommitTxns()

Returns the total committed transactions in the subscription

Returns:

the total committed transactions in the subscription

getTotalAbortTxns

long getTotalAbortTxns()

Returns the total aborted transactions in the subscription

Returns:

the total aborted transactions in the subscription

getTotalCommitOps

long getTotalCommitOps()

Returns the total number of operations that were part of committed transactions in the subscription. It is a sum of operations of all committed transactions.

Returns:

the total committed operations in the subscription

getTotalAbortOps

long getTotalAbortOps()

Returns the total number of operations that were part of aborted transactions in the subscription. It is a sum of operations of all aborted transactions.

Returns:

the total aborted operations in the subscription

getCurrentOpenTxn

long getCurrentOpenTxn()

Returns the current total number of open transactions in publisher that have not yet committed or aborted.

Returns:

the current total open transactions in the subscription

getTotalReconnect

long getTotalReconnect()

Returns the total number of reconnections to shards in subscription. The reconnection happens at level of shard when subscriber is unable to stream from a node in that shard, e.g., the master node is done and a new master is elected, and subscriber will reconnect to the new master of the shard.

Returns:

the total number of reconnections

getNumTokenRefreshed

long getNumTokenRefreshed()

Gets the number of times that token has been refreshed with the secure store. Refreshing a token includes both renewing an existing token and re-authenticating to obtain a new token if existing token cannot be renewed. For non-secure store, it always returns 0.

Returns:

the number of times that token has been refreshed
