Ok. basic a/b up and running. i have little to no experience with bigquery / google analytics, but i’m trying to set up the metrics. i’ve created a set of 3 tables in bigquery that are shaped like the example,

SELECT
  user_id,
  anonymous_id,
  received_at as timestamp,
  experiment_id,
  variation_id,
  context_page_path as url,
  context_user_agent as user_agent
FROM
  experiment_viewed

and … so on. … now i need to create a service account? and then within the tracking cb I’ll make a call to the bigquery api to write data?

you have GA for event data currently?

Instead of writing directly to BigQuery, You typically want to use an analytics event tracking system like Segment, Rudderstack, or Jitsu. Those systems queue up events and batch insert them to BigQuery. Much better scalability. Alternatively, you can use an all-in-one system like Mixpanel or Google Analytics which combines event tracking with data storage. In that case you don't need BigQuery at all.

for event data, currently, the only platforms I have any real experience with with are adobe analytics and optimizely

Ok. I'm happy to jump on a call if you have any questions or need any data pipeline advice.
