Random data generator (RandomGenerator) which emits POJO tuples as records +2. Dedup operator (Deduper) which accepts the POJO tuples and identifies unique and duplicate tuples. +3. Console operator (ConsoleUnique) for unique tuples +4. Console operator (ConsoleDuplicate) for duplicate tuples +5. Console operator (ConsoleExpired) for expired tuples + +The following properties are configured for using the Application: +1. ```dt.application.DedupExample.operator.RandomGenerator.prop.tuplesPerWindow``` - This is a limit on the number of tuples that will be generated by the Random Generator operator. +2. ```dt.application.DedupExample.operator.Deduper.prop.keyExpression``` - This is the pseudo java expression for deriving the key fields from the incoming POJO. +3. ```dt.application.DedupExample.operator.Deduper.prop.timeExpression``` - This is the pseudo java expression for deriving the time field in the incoming POJO. In case, ```timeExpression``` is not specified, then the System time is used to compute the expiration for the tuples. +4. ```dt.application.DedupExample.operator.Deduper.prop.expireBefore``` - The expiry time for incoming tuples in seconds. The keys in the system expire after every ```expireBefore``` seconds. +5. ```dt.application.DedupExample.operator.Deduper.prop.bucketSpan``` - The span of a single expiry bucket. When an expiry time elapses, the bucket as a whole is discarded from the system. This can be set keeping in mind the largest unit that can be discarded. For example, if ```expireBefore``` is set to 1 hour, and we are getting new data per minuite, it would make sense to set the ```bucketSpan``` to 1 minute or 5 minutes. + +Example values for these parameters have been specified in src/main/resources/META-INF/properties.xml. http://git-wip-us.apache.org/repos/asf/apex-malhar/blob/45735280/examples/dedup/XmlJavadocCommentsExtractor.xsl
