Class TurbineData

java.lang.Object

com.netflix.turbine.data.TurbineData

Direct Known Subclasses:

AggDataFromCluster, DataFromSingleInstance, TurbineDataDispatcher.UnitTest.TestData

public abstract class TurbineData
extends java.lang.Object

Base class for storing, passing around and delivering data from remote hosts in a JSON format ready for clients. See DataFromSingleInstance and AggDataFromCluster for concrete implementations Note that Turbine needs an aggregation dimension when combining data from multiple DataFromSingleInstance objects into a single AggDataFromCluster object. The name and type are used for this purpose. name + type is the unique aggregation key.

name identifies a single data point / event / metric etc whereas type is used to denote the sub stream type which then allows us to multiplex multiple sub streams over the same connection from an instance.

name and type can also be specified as filtering criteria when fetching the output stream from the turbine aggregator.
