MongoDB plugins for Orthanc DICOM Server

See: https://github.com/Doc-Cirrus/orthanc-mongodb

OVERVIEW

The repository contains two plugins to store the data in MongoDB database.

Installation

This chapter describes the process of installation with not too much details and not necessarily contain all how-to to resolve possible problems that might appear.

Prerequisites

• mongodb 3.6+ server
• Install jsoncpp
• Install/build mongoc library http://mongoc.org/libmongoc/current/installing.html
• Install/build mongo-cxx lib https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation/
• Download Ortanc sources or install orthanc-devel package

---

It is possible to install all dependencies manually (below you will find instructions) or you could try to use AUTO_INSTALL_DEPENDENCIES flag for cmake. In this way some dependencies will be installed automaticaly for orthanc-mongodb project. For more details refer to docs folder -> autoconfig.md file.

Plugin configuration setup

Add plugins in the Ortahc json configuration file:

    ...
  "Plugins" : [
    "libOrthancMongoDBIndex.dylib",
    "libOrthancMongoDBStorage.dylib"
  ],
  // MongoDB plugin confihuration section:
  "MongoDB" : {
    "EnableIndex" : true, // false to use default SQLite 
    "EnableStorage" : true, // false to use default SQLite 
    "ConnectionUri" : "mongodb://localhost:27017/orthanc_db",
    "ChunkSize" : 261120
  },
  ...

Also it's possible to configure the plugin with separate config options:

    "Plugins" : [
    "libOrthancMongoDBIndex.dylib",
    "libOrthancMongoDBStorage.dylib"
    ],
    "MongoDB" : {
        "host" : "customhost",
        "port" : 27001,
        "user" : "user",
        "database" : "database",
        "password" : "password",
        "authenticationDatabase" : "admin",
        "ChunkSize" : 261120
    }

NOTE: Setting up the ConnectionUri overrides the host, port, database params. So if the ConnectionUri is set, the other parameters except the ChunkSize will be ignored.

Testing is described with more details in here

Known Issues:

1. ConnectionUri must contain the database name due to the bug in the mongocxx driver CXX-1187
2. The Orthanc server should be compiled in Release or RelWithDebInfo mode to turn off assertions. There are asserts like that `./OrthancServer/ServerIndex.cpp: assert(index_.currentStorageSize_ == index_.db_.GetTotalCompressedSize());``` it involves full collection scan to aggregate the total AttachedFiles significantly slows the performance down.
