Bucket Management

This section provides an introduction to CEP Buckets and how different CEP backend Runtime can be configured to run long standing quires using WSO2 Complex Event Processor.

CEP Bucket is an instance of CEP Runtime Engine and it is the core of WSO2 Complex Event Processor. Total processing of received events and triggering of new events happens here.

The base of WSO2 Complex Event Processor (CEP) is Bucket. A bucket can be considered as an instance of a CEP back end runtime engine. For each and every bucket created in CEP Server, it creates an instance of the back end runtime. A bucket basically consists of three main attributes
