Hi All,

I am new to elasticsearch and I am looking for some help related to field  
level change notifications. My actual requirement is to notify multiple  
downstream applications regarding change in data of some columns (not the  
change in document version). We have multiple downstream applications  
pulling data from elasticsearch, so whenever there is a change in document  
version we use to notify them but as lots of downstream applications are  
there so we want to have notifications at a fine grained level i.e.  
downstream applications should be notified only when there is a change in  
those fields/columns that they need for their business.

I followed various links and suggestions like ShardsPluginsModule,  
PercolateService, IndexingOperationListener , etc. but still can't find  
some working example because I am not getting exactly where to plugin this  
util and I am also not sure about relying on these suggestions for  
distributed DC set-up. So I am requesting all the elasticsearch experts to  
spare some time to help me.

Thanks
