Constructor Detail

TimeBoundaryManager

public TimeBoundaryManager(org.apache.pinot.spi.config.table.TableConfig tableConfig,
                           org.apache.helix.store.zk.ZkHelixPropertyStore<org.apache.helix.zookeeper.datamodel.ZNRecord> propertyStore,
                           org.apache.pinot.common.metrics.BrokerMetrics brokerMetrics)

Method Detail

init

public void init(org.apache.helix.model.IdealState idealState,
                 org.apache.helix.model.ExternalView externalView,
                 Set<String> onlineSegments)

Initializes the time boundary manager with the ideal state, external view and online segments (segments with ONLINE/CONSUMING instances in the ideal state and pre-selected by the SegmentPreSelector). Should be called only once before calling other methods.

NOTE: idealState and externalView are unused, but intentionally passed in in case they are needed in the future.

onAssignmentChange

public void onAssignmentChange(org.apache.helix.model.IdealState idealState,
                               org.apache.helix.model.ExternalView externalView,
                               Set<String> onlineSegments)

Processes the segment assignment (ideal state or external view) change based on the given online segments (segments with ONLINE/CONSUMING instances in the ideal state and pre-selected by the SegmentPreSelector).

NOTE: We don't update all the segment ZK metadata for every external view change, but only the new added/removed ones. The refreshed segment ZK metadata change won't be picked up.

NOTE: idealState is unused, but intentionally passed in in case it is needed in the future.

refreshSegment

public void refreshSegment(String segment)

Refreshes the metadata for the given segment (called when segment is getting refreshed).
