Rengine

Unified and flexible rules engine platform, naturally suitable for scenarios where rules change frequently, such as real-time or near-real-time financial risk control, e-commerce promotion rules, operation and maintenance monitoring, IoT device alarms, online data cleaning and filtering, etc.

Architectures

• 

Requirements

• JDK 11.x +

• GraalVM java11-22.1 + (If the needs build executor native image)

• Maven 3.6 +

• Spring Boot 2.7.3 (Spring 5.3.22)

• Quarkus 2.12.2

• Redis Cluster 6 +

• Mongo 4.4.6 +

• MinIO 2021.x +

• Docker 20.x +

• Kubernetes 1.21 + (If the needs deploy to kubernetes)

• Flink 1.16.x + (If the need to run the Flink CEP job to process massive events. Notice: Must >= 1.16+ can support window restrictions)

• HBase 2.2.x + (Optional, If the needs to store raw events so that can trace back.)

Features

• Support online coding development rules models, and upload the custom dependency script libraries.

• Support Executor run by native mode running, Get a hundred times faster startup time (milliseconds) than the traditional JVM, which supports elastic and fast startup under the faas/serverless architecture very well. see: native-image

• Support Executor built-in multi SDKs(eg: common,tools,datasource,notifier), such as datasource sdk, which can be connected to multiple data-source instances by configuration. More built-in script SDKs to see: devel-executor-scriptsdk.md

• Support Executor JS(graal.js)(default), Python(beta), R(beta), Ruby(beta), Groovy(planning), etc. Executor supports the unified orchestration and execution of multiple scripting language engines. This is an epoch-making technological revolution, thanks to the powerful multi language runtime of graal.

• Support Controller actively scheduling invoke workflow graph.

• Support Controller, ApiServer register connecting to arthas tunnel for easy operator JVM troubleshooting (Only in JVM run mode).

• Support Job large-scale MMP parallel real-time state recognition based on Flink CEP.

• Support ApiServer static password login and standard OAuth2/OIDC authentication (the configure multiple), such as keycloak, github, etc.

• Support the multi-tenancy of based on kubernetes operator (resource shared and isolation), see: rengine-operator (progressing).

• Support automatic analysis of hit rate reports (progressing).
