[jira] [Updated] (STORM-1034) Create Fluent API for Kafka -
SpoutConfig & TridentKafkaConfig
[ https://issues.apache.org/jira/browse/STORM-1034?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rick Kellogg updated STORM-1034:
--------------------------------
Description:
Create Fluent Java API for construction of SpoutConfig & TridentSpountConfig. At present both of these classes have public instance variables and as such instantiation and validation is poor.
The use of a Fluent Java API will provide cleaner validation and the opportunity to deprecate properties while maintaining API compatibility.
Example:
{code:title=Bar.java|borderStyle=solid}
SpoutConfig simpleConfig = new SpountConfigBuilder()
.topicName("topicA")
.kafkaBrokerHosts("hostname:2181")
.stormClientID("storm-client-id")
.schema(new SchemeAsMultiScheme ())
.build();
{code}
