# nb -v run driver=mongodb yaml=mongodb-crud-basic tags=phase:schema connection=mongodb://127.0.0.1 database=testdb

description: |
  This workload emulates CRUD operations for the mongoDB.
  It generates a simple JSON document to be used for writes and updates.
  It's a counterpart of the Stargate's Documents API CRUD Basic workflow.
