Method Detail

setBolt

public BoltDeclarer setBolt(java.lang.String id,
                            IRichBolt bolt,
                            java.lang.Number parallelismHint)

Description copied from class: TopologyBuilder

Define a new bolt in this topology with the specified amount of parallelism.

Overrides:

setBolt in class TopologyBuilder

Parameters:

id - the id of this component. This id is referenced by other components that want to consume this bolt's outputs.

bolt - the bolt

parallelismHint - the number of tasks that should be assigned to execute this bolt. Each task will run on a thread in a process somewhere around the cluster.

Returns:

use the returned object to declare the inputs to this component

setSpout

public SpoutDeclarer setSpout(java.lang.String id,
                              IRichSpout spout,
                              java.lang.Number parallelismHint)

Description copied from class: TopologyBuilder

Define a new spout in this topology with the specified parallelism. If the spout declares itself as non-distributed, the parallelismHint will be ignored and only one task will be allocated to this component.

Overrides:

setSpout in class TopologyBuilder

Parameters:

id - the id of this component. This id is referenced by other components that want to consume this spout's outputs.

spout - the spout

parallelismHint - the number of tasks that should be assigned to execute this spout. Each task will run on a thread in a process somwehere around the cluster.

setSpout

public SpoutDeclarer setSpout(java.lang.String id,
                              IRichSpout spout,
                              java.lang.Number parallelismHint,
                              int maxExecutionCount)

setTerminalBoltClass

public void setTerminalBoltClass(java.lang.String terminalBoltClass)

createTopology

public HeronTopology createTopology()

Overrides:

createTopology in class TopologyBuilder

addAllGrouping

protected void addAllGrouping(java.lang.String child,
                              java.lang.String parent,
                              java.lang.String streamId)

Given a child component and its upstream component, add the allGrouping between them with given streamId

Parameters:

child - the child component id

parent - the upstream component id

streamId - the stream id
