MongoDB

MongoDB is a document database — schema-flexible JSON-shaped storage with indexes, aggregation pipelines, and replica sets. TantraDev uses MongoDB where the data model is genuinely document-shaped (CMS-like content, event payloads, user-defined schemas) and the relationships are shallow. For most transactional workloads we still default to PostgreSQL with `jsonb` columns where flexibility is needed.

TECHNOLOGY

PostgreSQL

PostgreSQL is an open-source relational database with strong ACID guarantees, MVCC concurrency, and rich extension surface (PostGIS, pg_partman, logical replication). It is the default datastore on every TantraDev engagement where the workload is transactional, the data has relationships, and the team needs the option to scale via partitioning and read replicas before reaching for a specialised store.
