Primary Key and foreign key

I am doing internship on InfluxDB for creating a shopping website.But on reading different article I found that I can not make foreign key or primary keys… If there any way by which I can create primary keys because my clients are demanding the project in InfluxDB.

InfluxDB is not a Relational Database Management System.

I’m pretty certain it does not support foreign keys, since these are the basis
of the R in RDBMS.

Assuming I have the right idea about what you want to do with a shopping
website, I would say that an RDBMS is essential, and that InfluxDB is simply
not the right tool for the job.
