  • Issue #903 SSL connection, etc for mongoc - NOTE: not for legacy driver - only the new, experimental API endpoints (needs testing)
  • Issue #1151 GET /entities?id=X is NO LONGER translated to GET /entities/X - that was a BAD IDEA

  • URI parameter options=simplified as an alias to options=keyValues
  • Support for the OPTIONS method for all NGSI-LD API endpoints
  • 'notifierInfo' and 'receiverInfo' for subscriptions

Replacing the deprecated MongoDB C++ Legacy driver with the newest MongoDB driver (mongoc v1.22.0):

  • Common functions for Getting and Listing tenants now use the new mongo driver
  • Common functions for Geo indices now use the new mongo driver
  • Common function for creation of the _id.id entities index now uses the new mongo driver
  • Using the tenant list when populating the subscription cache instead of querying the database (less Mongo C++ Legacy driver usage)
  • GET /subscriptions/{subId} now uses the subscription cache and no database access is done (less Mongo C++ Legacy driver usage)
  • GET /subscriptions now uses the subscription cache and no database access is done (less Mongo C++ Legacy driver usage)
  • Subscription Cache now uses mongoc and not the old legacy driver
  • Subscription Cache Counters are now updated using mongoc and not with the old legacy driver
  • PATCH subscriptions/{subId} now uses the new mongoc driver

Experimental Features

  • to turn on - start the broker with -experimental.
    Note that this is experimental implementations, not yet thoroughly tested.
    They all pass the basic functional tests, and seem to work just find, but, no promises made.
  • Fresh implementations of services using 'mongoc' (the new MongoDB driver) instead of mongoBackend+Legacy driver:
    • PUT /entities/{entityId} (not supported if -experimental is not used)
    • PATCH /entities/{entityId} (not supported if -experimental is not used)
    • POST /entities (two versions: legacy and mongoc - mongoc version if -experimental is used)
    • GET /entities (two versions: legacy and mongoc - mongoc version if -experimental is used)
    • GET /entities/{entityId} (two versions: legacy and mongoc - mongoc version if -experimental is used)
    • POST /subscriptions (two versions: legacy and mongoc - mongoc version if -experimental is used)
    • DELETE /subscriptions/{subId} (two versions: legacy and mongoc - mongoc version if -experimental is used)
  • Support for LanguageProperty attributes
  • Support for URI parameter 'observedAt' for PATCH /entities/{entityId} in combination with options=keyValues - update existing observedAt sub-attributes
