Deprecated features are features that Orion stills support but that are not mantained or evolved any longer. In particular:
- Bugs or issues related with deprecated features and not affecting any other feature are not addressed (they are closed in github.com as soon as they are spotted).
- Documentation on deprecated features is removed from the repository documentation. Documentation is still available in the documentation set associated to older versions (either in the respository release branches or the pre-0.23.0 documentation in the FIWARE wiki).
- Deprecated functionality is eventually removed from Orion. Thus you are strongly encouraged to change your implementations using Orion in order not rely on deprecated functionality.
A list of deprecated features and the version in which they were deprecated follows:
- Deprecated command line argument in Orion 0.26.1:
- --silent. Suppress all log output except errors (Please use -logLevel ERROR instead)
- ONTIMEINTERVAL subscriptions are deprecated since Orion 0.26.0. ONTIMEINTERVAL subscriptions have several problems (introduce state in CB, thus making horizontal scaling configuration much harder, and makes it difficult to introduce pagination/filtering). Actually, they aren't actually needed, as any use case based on ONTIMEINTERVAL notification can be converted to an equivalent use case in which the receptor runs queryContext at the same frequency (and taking advantage of the features of queryContext, such as pagination or filtering).
- XML is deprecated since Orion 0.23.0.
- Deprecated command line arguments in Orion 0.21.0 (removed in 0.25.0):
- -ngsi9. The broker runs only NGSI9 (NGSI10 is not used).
- -fwdHost . Forwarding host for NGIS9 registerContext when the broker runs in "ConfMan mode".
- -fwdPort . Forwarding port for NGIS9 registerContext when the broker runs in "ConfMan mode".
- Configuration Manager role (deprecated in 0.21.0, removed in 0.25.0)
- Associations (deprecated in 0.21.0, removed in 0.25.0).
