Questions 问题
Comparing it with Spark: Apache Spark is actually a batch processing. 将它与Spark进行比较:Apache Spark实际上是一个批处理。 If you consider Spark streaming (which uses spark underneath) then it is micro-batch processing.
如果你考虑Spark流(它使用下面的spark),那么它就是微批处理。 In contrast, Apache apex is a true stream processing.
相比之下,Apache apex是一个真正的流处理。 In a sense that, incoming record does NOT have to wait for next record for processing.
从某种意义上说,传入记录不必等待下一个记录进行处理。 Record is processed and sent to next level of processing as soon as it arrives.
记录一经处理即被处理并发送到下一级处理。
Currently, work is under progress for adding support for integration of Apache Apex with machine learning libraries like Apache Samoa, H2O Refer https://issues.apache.org/jira/browse/SAMOA-49 目前,正在努力增加对Apache Apex与Apache Samoa,H2O等机器学习库集成的支持。请参阅https://issues.apache.org/jira/browse/SAMOA-49
Currently, it has support for Java, Scala. 目前,它支持Java,Scala。
https://www.datatorrent.com/blog/blog-writing-apache-apex-application-in-scala/ For Python, you may try it using Jython. https://www.datatorrent.com/blog/blog-writing-apache-apex-application-in-scala/对于Python,您可以使用Jython进行尝试。 But, I haven't not tried it myself.
但是,我自己并没有尝试过。 So, not very sure about it.
所以,不太确定。
Integration with Spark may not be good idea considering they are two different processing engines. 考虑到它们是两种不同的处理引擎,与Spark集成可能不是一个好主意。 But, Apache apex integration with Machine learning libraries is under progress.
但是,Apache apex与机器学习库的集成正在进行中。
