fastiot_core_services.time_series.env module¶

class fastiot_core_services.time_series.env.TimeSeriesConstants[source]¶

property subscribe_subject: str¶

FASTIOT_TIME_SERIES_SUBSCRIBE_SUBJECT¶

Set the subject to listen to. It defaults to > meaning everything below Thing. For more details about how to specify (wildcard) subjects please refer to the nats.io documentation at https://docs.nats.io/nats-concepts/subjects If you want to listen to a specific topic you can change FASTIOT_TIME_SERIES_SUBSCRIBE_SUBJECT to your value, but you can only listen to subtopics of Things. So if you want to listen to Thing.machine_1 you change FASTIOT_TIME_SERIES_SUBSCRIBE_SUBJECT to “machine_1”. It is not possible to listen to “not_Thing.machine1”

property request_subject: str¶

FASTIOT_TIME_SERIES_REPLY_SUBJECT¶

Sets the subject the time series module will listen on for requests with fastiot.msg.hist.HistObjectReq. It defaults to things.

If you have only one time series storage this default should be fine for you. Using this is especially helpfully when running multiple time series storages listening on different subjects defined with FASTIOT_TIME_SERIES_SUBSCRIBE_SUBJECT.
