Multiple Engines

An engine is a concept brought to plugins by the kuzzle-plugin-commons package.

Basically, it allows to have a set of indexes and related collections, with potentially different features, and to route the incoming payloads to a specific index, for whatever reason (volume, tenant, origin, etc.).

Usually, there is no such need and all the traffic is allocated to the single default engine/index, whose name is defined in the plugin configuration.

Otherwise, use your own algorithm to decide which engine is in charge to host the device data and tell it to the decodedPayload:

AppDecoder.ts - decode() implementation

  /* inside decode() ... */
  decodedPayload.setEngineId(deviceReference, 'my-engine')

There is nothing else to do. If the index doesn’t exist yet, it will be created on the fly.
