Description

As part of the Document Handling capability in Camunda, we need to introduce the local file system document store implementation.

Key requirements

• Documents must be stored as files on the local disk of the system where Camunda is running
• This document store is not production-ready and is mainly intended for local development, therefore some limitations are allowed
• The local document store implementation must be enabled by default on self-managed installations
• The root directory path must be configurable via environment variables

Supported operations: create, get, delete documents, document hash verification

Unsupported operations: create document link

Further limitations to be considered:

• Should we support resource-based authorization? Metadata can be stored in a separate file, allowing us to access process definition key & process instance key. It can also be fine to skip this in the first iteration.
