Rethinkdb is an open source database.

The best thing about the rethinkdb is that it always keeps connection between backend and database to exchange the information, As soon as you update anything in databsee it will immediately be shown on frontend with no delay .
RethinkDB is the first open-source, scalable JSON database built from the ground up for the realtime web. It inverts the traditional database architecture by exposing an exciting new access model – instead of polling for changes, the developer can tell RethinkDB to continuously push updated query results to applications in realtime. RethinkDB’s realtime push architecture dramatically reduces the time and effort necessary to build scalable realtime apps.
In addition to being designed from the ground up for realtime apps, RethinkDB offers a flexible query language, intuitive operations and monitoring APIs, and is easy to setup and learn.

install the dependencies pip install rethinkdb
And for the code expalanation to my rethink.py file
