Zeebe is the process automation engine powering Camunda 8. While written in Java, you do not need to be a Java developer to use Zeebe. To learn more about Zeebe, visit the Camunda docs.
This is a small overview of the contents of the different modules:
utilcontains custom implementations of building blocks like an actor scheduler, buffer allocations, and metrics. Its parts are used in most of the other modulesprotocolcontains the SBE definition of the main message protocolbpmn-modelis a Java API for BPMN process definitions used for parsing etc.msgpack-*is a custom msgpack implementation with extensions to evaluate json-path expressions on msgpack objectsdispatcheris a custom implementation of message passing between threadsservice-containeris a custom implementation to manage dependencies between different serviceslogstreamsis an implementation of an append-only log backed by the filesystemtransportis our abstraction over network transportsgatewayis the implementation of the gRPC gateway, using our SBE-based protocol to communicate with brokersgateway-protocolcontains the gRPC definitions for the Zeebe client-to-gateway protocolzb-dbis our RocksDB wrapper for state managementengineis the implementation of the event stream processorbrokercontains the Zeebe broker which is the server side of Zeebeclient-javacontains the Java Zeebe clientatomixcontains transport, membership, and consensus algorithmsbenchmarkcontains utilities the team uses to run load testsexporters/elasticsearch-exportercontains the official Elasticsearch exporter for Zeebejournalcontains the append-only log used by the consensus algorithmsnapshotsabstracts how state snapshots (i.e.zb-db) are handled
