Get data from elastic apart from polling

Elastic Stack Elasticsearch
1

Dear,

I am interested in developing some code which requires some data from Elastic. At the moment I only saw polling methods to get data. Is there any other method ? I am mainly interested in get realtime data, may be pub/sub scheme ?

Regards,
Xavi

If the data is in Elasticsearch you need to poll for it one way or another as there is no push mechanism. Diverting data at the application layer at indexing time may also be an option.
