| 2018-10-30 05:50:58 +0100 | commented answer | Multiple orion with single mongodb instance fails to process subscriptions I have tried the following configuration. Multiple orion instances are active at the same time and the proxy dynamically distributes load among the orion instances. In such a deployment what I find - only one among the active orion instances is able to process onchange subscription for an entity |
| 2018-10-22 10:50:11 +0100 | asked a question | Can multiple fiware orion work with same mongodb backend? I have tried connecting multiple orion instances from different machines to the same mongodb backend. The issue I have observed is that only one among the orion instances is able to process onchange subscription registered against attribute of an entity. My question is - is it a valid practice of having multiple active instances of orion independantly handling incoming requests connected to the same mongodb backend. Does such a deployment configuration work in the same manner, in comparision to single instance of orion connected to mongodb backend. I have tried this with orion version 0.23 and mongodb version 3.4 |
| 2018-10-22 10:50:10 +0100 | asked a question | Multiple orion with single mongodb instance fails to process subscriptions I am trying to connect multiple orion instances to the same mongodb backend. While I am able to recieve context data from South bound iot devices into orion, only one among the orion instances is processing the onchange subscription request registered for onchange of context data of an entity attribute. Is it a valid practice to have multiple orion instances connect to the same mongodb backend and if so, if 2 different orion instances recieve context attribute data of the same entity will it trigger pre-registered onchange subscription. Do I need to configure something in orion or Mongo for this to work I am using orion 0.23 and Mongo 3.4 |
