Trending service should consume events from both DCs
Closed, DeclinedPublic


Right now the trending service consumes only from the local-DC topics, so in codfw there's no trending articles in memory. When DC switchover will occur, for 24 hours trending articles would be inaccessible until the service in codfw rebuilds the state. We need to consume both from the local DC and the mirrored topics from the remote DC.

@Pchelolo, is this something you plan to work on, or are we waiting for Reading to pick this up?

It's basically a small config change in puppet. I can do it.

Pchelolo edited projects, added Services (done); removed Services (next).

Since the trending service has been put out of production this is not relevant any more T180384
