Method Detail

startInner

public boolean startInner()
                   throws java.lang.Exception

Specified by:

startInner in class AbstractVeniceService

Returns:

true if the service is completely started, false if it is still starting asynchronously (in this case, it is the implementer's responsibility to set AbstractVeniceService.serviceState to AbstractVeniceService.ServiceState.STARTED upon completion of the async work).

Throws:

java.lang.Exception

stopInner

public void stopInner()
               throws java.lang.Exception

Specified by:

stopInner in class AbstractVeniceService

Throws:

java.lang.Exception

setOffsetToSkip

public void setOffsetToSkip(java.lang.String clusterName,
                            long offset,
                            boolean skipDIV)

Skip admin message with specified offset for the given cluster.

getLastSucceededExecutionIdInCluster

public java.lang.Long getLastSucceededExecutionIdInCluster(java.lang.String clusterName)

Get the last succeeded execution id for the given cluster.

Parameters:

clusterName - name of the Venice cluster.

Returns:

last succeeded execution id for the given cluster.

getLastSucceededExecutionId

public java.lang.Long getLastSucceededExecutionId(java.lang.String storeName)

Get the last succeeded execution id for the given store.

Parameters:

storeName - name of the store.

Returns:

last succeeded execution id for the given store.

getLastExceptionForStore

public java.lang.Exception getLastExceptionForStore(java.lang.String storeName)

Get the encountered exception during admin message consumption for the given store.

Parameters:

storeName - name of the store.

Returns:

last encountered exception.

getFailingOffset

public long getFailingOffset()

Returns:

The first or the smallest failing offset.

getAdminTopicMetadata

public java.util.Map<java.lang.String,java.lang.Long> getAdminTopicMetadata(java.lang.String clusterName)

Returns:

cluster-level execution id, offset, and upstream offset in a child colo.

updateAdminTopicMetadata

public void updateAdminTopicMetadata(java.lang.String clusterName,
                                     long executionId,
                                     long offset,
                                     long upstreamOffset)

Update cluster-level execution id, offset, and upstream offset in a child colo.
