[mongodb] MongoDB

# Summary

MongoDB integration for Drupal. This is a collection of several modules which allow sites to store different types of Drupal data in MongoDB.

# Project URL

https://www.drupal.org/project/mongodb

# Where is the code?

• 8.x-1.x: https://www.drupal.org/node/646198
• 8.x-2.x: https://github.com/FGM/mongodb

# Estimated completion date

• 8.x-1.x: unknown
• 8.x-2.0: 01/09/2018. Currrently in beta1.
• Track progress on ContribKanban for Drupal MongoDB

# Dependencies

• 8.x-1.x: mongo extension, and a specific core commit between 8.0.0-beta9 and beta10
• 8.x-2.x: mongodb extension ≥ 1.1.7, mongodb library ^1.2.0 (via composer), core 8.5.x or 8.6.x, PHP 7.x

# Who's doing the port?

• Most of the code in the current 8.x-1.x branch has been created by chx
• The 8.x-2.x branch has been created by fgm

# What help do they need?

• Patch review for the Path feature on 7.x
• Patches for new features on 8.2.x
• Maintainers for the Block* and Field Storage components on 7.x

# D8 roadmap

• Step 1: finalize 8.x-2.0, containing the base mongodb module, to enable custom development from that base, and the mongodb_watchdog logger module and mongodb_storage key-value store
• Step 2: 8.x-2.1 containing at least the cache component
• ...later versions each adding at least one additional component

# Background and reference information

• The new MongoDB PHP extension : https://speakerdeck.com/jmikola/rethinking-extension-development-for-php...
• MongoDB on Github: https://github.com/mongodb

At the 2015-12-01 Paris MUG meetup, the main author of the new driver, Jeremy Mikola, also of Doctrine ODM fame, advised this project (conversation with fgm) to:

• use the new driver for ongoing 8.x work
• not switch to it for existing work (D6, D7)
• possibly use the low-level mongodb extension directly instead of using the higher-level user-space PHP library, since this package is in effect itself a driver, and the user-space driver is geared towards simpler applications. Actually, since 8.x-2.x made progress, it became apparent that we could very well use the library, which saved time significantly
• not use the ODM because it does not mix well with the Drupal entity model. Confirmed with the current work on 8.x-2.x.
