Questions tagged [mongodb-java-3.3.0]

The tag is useful for mongodb java driver version 3.3.0 for newly added features. This would be used most of the time along with the mongodb-java tag.

New features of the 3.3 java driver included:

  • Cluster Monitoring in the synchronous and asynchronous drivers
  • Command Monitoring in the asynchronous driver (support in the synchronous driver was added in a previous release)
  • Additional query parameters in the connection string
  • GridFS in the asynchronous driver
  • Additional configuration options for GSSAPI authentication.
  • JNDI ObjectFactory implementation
