Abstract
In this paper we present SOA based CLAS12 event Reconstruction and Analyses (CLARA) framework. CLARA design focus is on two main traits: real-time data stream processing, and service-oriented architecture (SOA) in a flow based programming (FBP) paradigm. Data driven and data centric architecture of CLARA presents an environment for developing agile, elastic, multilingual data processing applications. The CLARA framework presents solutions capable of processing large volumes of data interactively and substantially faster than batch systems.
Highlights
Software systems, including physics data processing (PDP) applications have a distinct component based structure
The first layer is the service-bus that provides an abstraction of the xMsg publish-subscribe messaging system[2]. xMsg is using the ZeroMQ[3] socket library and implements messaging patterns like topic pub-sub, workload distribution, and request-response
Every service from the service layer or component from the orchestration-layer communicates via the service-bus, which acts as a messaging tunnel between CLAS12 event Reconstruction and Analyses (CLARA) components
