=== Context Given we are expecting a large dump of raw data if we don't sample, the question is raised if we need to sample in the sessionTicks that we collect.

=== Context Once session_tick tracking is rolled out to all wikis, the dataset will quickly become too large if we don't institute sampling. Details are in Marcel's comment here: https://phabricator.wikimedia.org/T271455#6741794 As we sample, we need to consider how representative the data is for key breakdowns of the data (e.g. wiki, country, day). Is there a minimum threshold for sessions we should set? What do we know or can we learn about activity within key breakdowns to inform sampling strategy?
