Map old cookie value to the new cookie

[marcin-j]

Hi team,

I've opened this topic on Snowplow discourse. I did some digging, and it seems like it's not possible to do that easily with the current collector.

I've written a small update to the collector code to take the oldCookieName into consideration while mapping the old value to the new cookie name.

I'm not really efficient in Scala so hopefully, you can help me out with making this better :) The first thing would be to point me to someplace where I could add some unit tests I guess.

cheers :)

Hey,

I still think this could be a valid feature, as a response that I got here would always require us to later map those two domain user ids in database - either rewrite them, for example, after a year, when the cookie expires; or map them continuously.

Hi guys,

I forgot about this issue, but it would be great to get some feedback from you because I'm still interested in merging this.

Is there any chance of getting this feature merged, or should this PR just be closed?
