Introduction to DocumentDB
DocumentDB is the engine powering vCore-based Azure Cosmos DB for MongoDB. It offers a native implementation of document-oriented NoSQL database, enabling seamless CRUD operations on BSON data types within a PostgreSQL framework. Beyond basic operations, DocumentDB empowers you to execute complex workloads, including full-text searches, geospatial queries, and vector embeddings on your dataset, delivering robust functionality and flexibility for diverse data management needs.
PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads.
Components
The DocumentDB project comprises of two primary components, which work together to support document operations.
pg_documentdb_core: PostgreSQL extension introducing BSON datatype support and operations for native Postgres.pg_documentdb: The public API surface for DocumentDB providing CRUD functionality on documents in the store.
