Of course there can be. Multiple cases exist. Light as a particle and light as a wave.

Re:Building a chat app in 8 minutes with Phoenix on Monday March 19, 2018 @03:53PM (#16622455)
Build implies something other than cut-paste or git clone ./make

This title is misleading.

Install a chap app in 8 minutes would be more appropriate, although really it's just sensationalism.

Ad Tech has no need for realtime data viewing or aggregation (in this manner), even for platform log data. Offline parallel processing is the standard. Redshift is particularly efficient, while others use Spark or other ad-hoc solutions.

For users, you always want mediation/adjustment steps that (can) modify realtime data to provide timesliced totals. For developers/administrators, you want to be able to persist data. Running totals in memory are too fragile to be reliable. There is an assumption of errors, misconfigurations, and bad actors at all times in AdTech.
