Continuously synchronize your MongoDB data to Elasticsearch

Transporter, Compose’s service for moving data from MongoDB to Elasticsearch, has already proven to be popular with our Elasticsearch and MongoDB users as it allows them to use both databases on the same dataset. But we can always make it better, and we just have with the new Continuous mode for Transporter. With this new…

Drupal 8 progress from my / MongoDB perspective: update #29

Perhaps the most important development is the final naming of what was field/field instance in Drupal 7: in Drupal 8 these are configuration entities. The machine names are field_storage_config and field_config. There has been several renames but we have settled on these finally (although the field_config rename is not yet in).

The things that do not change the storage of it go into the instance. However, some confusion might come from already existing Drupal 8 documentation and other materials where field_config was the name for what ended up as field_storage...

Java Using SSL To Connect to MongoDB With Access Control

Regardless of authentication, communication between client and server is encrypted in both directions. In this example, the client actually authenticates with the database, albeit using a username/password rather than presenting a certificate. In addition, I also show how the client application can run operations against a database that has access control rules defined for...
