  Data Analytics provides core business reporting needs in many software
companies, acts as a source of truth for key information, and enables building
advanced solutions, e.g., predictive models, machine learning, real-time
recommendations, to grow the business.
  A self-service, multi-tenant, API-first, and scalable data platform is the
foundational requirement in creating an enterprise data marketplace, which
enables the creation, publishing, and exchange of data products. Such a
marketplace enables the exploration and discovery of data products, further
providing high-level data governance and oversight on marketplace contents. In
this paper, we describe our way to the gourmet data product marketplace. We
cover the design principles, the implementation details, technology choices,
and the journey to build an enterprise data platform that meets the above
characteristics. The platform consists of ingestion, streaming, storage,
transformation, schema generation, fail-safe, data sharing, access management,
PII data automatic identification, self-service storage optimization
recommendations, and CI/CD integration.
  We then show how the platform enables and operates the data marketplace,
facilitating the exchange of stable data products across users and tenants. We
motivate and show how we run scalable decentralized data governance. All of
this is built and run for Cimpress Technology (CT), which operates the Mass
Customization Platform for Cimpress and its businesses. The CT data platform
serves 1000s of users from different platform participants, with data sourced
from heterogeneous sources. Data is ingested at a rate of well over 1000
individual messages per second and serves more than 100k analytical queries
daily.
