isHandoffComplete

public com.google.common.util.concurrent.ListenableFuture<Boolean> isHandoffComplete(String dataSource,
 SegmentDescriptor descriptor)

Description copied from interface: CoordinatorClient

Checks if the given segment is handed off or not.

Specified by:

isHandoffComplete in interface CoordinatorClient

fetchSegment

public com.google.common.util.concurrent.ListenableFuture<DataSegment> fetchSegment(String dataSource,
 String segmentId,
 boolean includeUnused)

Description copied from interface: CoordinatorClient

Fetches segment metadata for the given dataSource and segmentId. If includeUnused is set to false, the segment is not returned if it is marked as unused.

Specified by:

fetchSegment in interface CoordinatorClient

fetchServerViewSegments

public Iterable<ImmutableSegmentLoadInfo> fetchServerViewSegments(String dataSource,
 List<org.joda.time.Interval> intervals)

Description copied from interface: CoordinatorClient

Fetches segments from the coordinator server view for the given dataSource and intervals.

Specified by:

fetchServerViewSegments in interface CoordinatorClient

fetchUsedSegments

public com.google.common.util.concurrent.ListenableFuture<List<DataSegment>> fetchUsedSegments(String dataSource,
 List<org.joda.time.Interval> intervals)

Description copied from interface: CoordinatorClient

Fetches segment metadata for the given dataSource and intervals.

Specified by:

fetchUsedSegments in interface CoordinatorClient

fetchDataSourceInformation

public com.google.common.util.concurrent.ListenableFuture<List<DataSourceInformation>> fetchDataSourceInformation(Set<String> dataSources)

Description copied from interface: CoordinatorClient

Retrieves detailed metadata information for the specified data sources, which includes RowSignature.

Specified by:

fetchDataSourceInformation in interface CoordinatorClient

fetchBootstrapSegments

public com.google.common.util.concurrent.ListenableFuture<BootstrapSegmentsResponse> fetchBootstrapSegments()

Description copied from interface: CoordinatorClient

Fetch bootstrap segments from the coordinator. The results must be streamed back to the caller as the result set can be large.

Specified by:

fetchBootstrapSegments in interface CoordinatorClient

withRetryPolicy
