Solr索引镶木地板文件(Solr indexing parquet file)

我有一个solr实例启动并运行它应该读取镶木地板文件索引。 现在,我正在将镶木地板转换为平面文本文件,然后使用solr索引它们。 我想知道是否可以直接读取镶木地板文件供Solr使用?

谢谢


I have a solr instance up and running and it should read parquet files to index. Right now, I am converting the parquet to flat text file and then having solr index them. I'd like to know if it is possible to read the parquet file directly for Solr to consume?

Thanks

可以通过WCF使用MEF,我过去曾参与过类似的项目。 您可以通过MEF公开插件DLL中的函数,假设MEF接口的实现者正在实现一个函数,该函数使用自己的端点启动新的WCF服务,然后从主服务调用该函数。

请参阅下面的一些示例项目,尽管它们都没有按照您的要求进行操作,但是MEF插件可能有一个服务主机可以使用自己的端点开始自己的服务。

It is possible to use MEF through WCF, I have worked on a similar project in the past. You could expose functions from the plugin DLL's through MEF assume the implementer of the MEF interface is implimenting a function that starts a new WCF service with it's own end points, then call that function from the main service.

See some sample projects below, although none of them are doing what you are asking it is possible that the MEF plugins could have a service host that's starting their very own service with their own end points.
