Subject Enrich streaming data with small lookup data that slowly changes over time
Date Tue, 21 Apr 2020 02:51:24 GMT
Hi community,

I have a stream of traffic data with a service_id in it.
I'm enriching this data with a map of (service_id, service_name), which
only has 10 ~ 20 pairs and is read from config file.

The problem I'm facing now is, this map changes from time to time, and I
don't want to redeploy the application to just change the map in the config
file.

Is there an existing solution for solving this problem?

Thanks in advance!

Best regards,
Mu
