Processors

Joins two streams together based on a field from each stream.

Two join types are supported: inner and left.

Joins are based on a window that you can configure based on time or count.

Allows you to configure rule conditions that route events to different streams.

Standard conditional operators are supported for rules.

Configuring a rule has two modes:

• General: Guided rule creation using drop-down menus.

• Advanced: Write complex SQL to construct a rule.

Rules are translated to SQL to be applied on the stream.

An event goes through all the conditions and if it matches multiple rules the event is sent to all the matching output streams.

Performs functions over windows of events.

Two types of windows are supported: tumbling and sliding.

You can create window criteria based on time interval and count.

Window functions supported out of the box include: stddev, stddevp, variance, variancecep, avg, min, max, sum, count. The system is extensible to add custom functions as well.

Applies transformations to the events in the stream

Extensive set of OOO functions and the ability to add your own functions

Performs a standard if-else construct for routing.

The even is routed to the first rule it matches. Once an event has matched a rule, no further condition search is performed.

Executes a PMML model that is stored in the Model Registry. PMML has been minimally tested as part of the Tech Preview, and should not be used.
