Method Detail

streamConfigList

public List<StreamConfig> streamConfigList()

Description copied from interface: StreamTracker

Returns the list of stream config, to be processed by the current application. Note that the streams list CAN be changed during the application runtime. This method will be called periodically by the KCL to learn about the change in streams to process.

Specified by:

streamConfigList in interface StreamTracker

Returns:

List of StreamConfig

formerStreamsLeasesDeletionStrategy

public FormerStreamsLeasesDeletionStrategy formerStreamsLeasesDeletionStrategy()

Description copied from interface: StreamTracker

Strategy to delete leases of old streams in the lease table. Note that the strategy CANNOT be changed during the application runtime.

Specified by:

formerStreamsLeasesDeletionStrategy in interface StreamTracker

Returns:

StreamsLeasesDeletionStrategy

isMultiStream

public boolean isMultiStream()

Description copied from interface: StreamTracker

Returns true if this application should accommodate the consumption of more than one Kinesis stream.

This method must be consistent. Varying the returned value will have indeterminate, and likely problematic, effects on stream processing.

Specified by:

isMultiStream in interface StreamTracker
