Holon platform MongoDB Datastore module

Latest release: 5.2.1

This is the reference MongoDB implementation of the Holon Platform Datastore API, using the MongoDB Java driver for data access and manipulation.

The following interaction models are supported:

  • Synchronous interaction, using the holon-datastore-mongo-sync artifact.
  • Asynchronous interaction, using the holon-datastore-mongo-async artifact.
  • Reactive interaction, using the holon-datastore-mongo-reactor artifact and the Project Reactor library.

See the Datastore API documentation for information about the Holon Platform Datastore API.

A full Spring and Spring Boot integration is provided, which includes auto-configuration facilities and a set of starters to quickly setup project dependencies.

Just like any other platform module, this artifact is part of the Holon Platform ecosystem, but can be also used as a stand-alone library.

See Getting started and the platform documentation for further details.

Code structure

See Holon Platform code structure and conventions to learn about the "real Java API" philosophy with which the project codebase is developed and organized.
