Create an average forecaster

3

See https://otexts.com/fpp2/simple-methods.html#simple-methods We should add a window length to allow us to take the average of the last n observations.

DetectorRepositoryImpl.findByUuid() assumes at least one result

1

In the following code ``` @Override public DetectorDocument findByUuid(String uuid) { val queryBuilder = QueryBuilders.termQuery("uuid", uuid); val searchSourceBuilder = elasticsearchUtil.getSourceBuilder(queryBuilder).size(DEFAULT_ES_RESULTS_SIZE); val searchRequest = elasticsearchUtil.getSearchRequest(searchSourceBuilder, DETECTOR_INDEX, DETECTOR_DOC_TYPE); return getDetectorsFromElasticSearch(searchRequest).get(0); } ```...

Remove Kafka notifier app

In the Kafka module we are no longer using the notifier app. Remove it.

Currently we use various legacy factories to create ForecastingDetectors from a specific point forecaster. All of the legacy factories use the Welford interval forecaster. We need a ForecastingDetectorFactory for two...

Currently DetectorRepository has finders that return simple Lists. This means that we can end up with unbounded result sets. This is an actual risk as there are potentially millions of...

Create kafka-junit test for KafkaAnomalyDetectorMapper

1

Currently the unit test is based on Kafka's `test-utils` package, but `kafka-junit` provides deeper support as it allows us to set up a mock broker with input/output topics that we...

Create kafka-junit test for KafkaAnomalyDetectorManager

Currently the unit test is based on Kafka's `test-utils` package, but `kafka-junit` provides deeper support as it allows us to set up a mock broker with input/output topics that we...

In general we would prefer not to use Spring for the Kafka Streams apps, as these are pretty lightweight and don't really warrant pulling Spring in. The Notifier app is...

Support left-, right- and two-tailed anomaly detection in general

1

In many cases, we want to generate anomalies only if observations fall too far on either one or the other side of some point forecast. For example, for bookings, we...
