Constructor Detail

SplitSchedulingContext

public SplitSchedulingContext(ConnectorSplitManager.SplitSchedulingStrategy splitSchedulingStrategy,
                              boolean schedulerUsesHostAddresses,
                              WarningCollector warningCollector)

Parameters:

splitSchedulingStrategy - the method by which splits are scheduled

schedulerUsesHostAddresses - whether host addresses are take into account when choosing where to schedule remotely accessible splits. If this is false, the connector can return an empty list of addresses for remotely accessible splits without any performance loss. Non-remotely accessible splits always need to provide host addresses.
