问题描述
我在文本分析和提取信息的过程中使用了 UIMA .流水线同时执行6个进程而失败.
I used UIMA in a process for analyzing and extracting information since text. The pipeline fails with 6 simultaneous processes.
我认为我需要使用横向扩展工具，例如 UIMA-Ducc 和 UIMA-AS ，但我不清楚.
I think that I need to use a scaleout tool, like UIMA-Ducc and UIMA-AS, but I don't see clearly which.
何时使用每个?他们有什么区别?
When to use each one? Which are their differences?
推荐答案
UIMA-AS提供了用于部署UIMA管道的机制.本质上，UIMA-AS允许用户在UIMA组件的前面放置一个队列，以便它可以在不同的线程或不同的进程中运行. UIMA-AS处理CASes的线程和进程间传输.除了一些简单的bash脚本之外，UIMA-AS不为用户进程提供生命周期管理.
UIMA-AS provides mechanisms for deploying a UIMA pipeline. Essentially, UIMA-AS allows users to put a queue in front of a UIMA component so that it can run in a different thread or in a different process. UIMA-AS handles threading and the interprocess transport of CASes. Other than some simple bash scripts, UIMA-AS does not provide life-cycle management for user processes.
DUCC是一个群集控制器，除其他功能外，它还为UIMA-AS服务提供生命周期管理. DUCC还提供了一种用于扩展具有多个线程和多个进程的UIMA管道并将工作馈送到管道实例的机制.这称为DUCC作业. DUCC作业是从UIMA核心组件创建的，不需要UIMA-AS的知识.
DUCC is a cluster controller that, among other things, provides life-cycle management for UIMA-AS services. DUCC also provides a mechanism for scaling out a UIMA pipeline with multiple threads and multiple processes and feeding work to the pipeline instances; this is called a DUCC Job. DUCC jobs are created from core UIMA components, no knowledge of UIMA-AS required.
