Release notes for MongoDB connector v4.2.0. MongoDB Connector 4.2.0 uses Mongo Driver 3.2.

New Features

  • New operation Insert Documents added; this supports multiple inserts and batch integration.

  • Upgraded MongoDB Java Driver - Now compatible Mongo Java Driver v3.2.

  • New processors - FindAndUpdateDocument which is an implementation of Mongo Find and Modify operation. The other new processor is UpdateDocumentsByFunctions, which will let you provide a set of MongoDB operators instead of just one as before.

Release notes for version 4.0.2 of the MongoDB connector.

This is a minor release with a few bug fixes.

  • Fixed documentation issues.
