Class LocalStreamBuilder

java.lang.Object

org.apache.streams.local.builders.LocalStreamBuilder

All Implemented Interfaces:

Serializable, StreamBuilder

public class LocalStreamBuilder
extends Object
implements StreamBuilder

LocalStreamBuilder implementation to run a data processing stream in a single JVM across many threads. Depending on your data stream, the JVM heap may need to be set to a high value. Default implementation uses unbound ConcurrentLinkedQueue to connect stream components.

LocalStreamBuilder

public LocalStreamBuilder()

Creates a local stream builder with all configuration resolved by typesafe

LocalStreamBuilder

@Deprecated
public LocalStreamBuilder(Map<String,Object> streamConfig)

Deprecated. use LocalRuntimeConfiguration constructor instead

Creates a local stream builder with a config object and default maximum internal queue size of 500

Parameters:

streamConfig -
