I am working with Apache Spark and MongoDB in Java. I have a database with a lot of documents, maybe more than 30,000,000 million documents.
Every time I make a connection in my project I charge this entire collection in a Dataset which is very heavy.
I would like to know how I can do to obtain certain Mongo data and store it in a Dataset. That is, the documents that are between the "Date" 2017005 and 2017010.
Greetings and thanks.
