We are looking to build a solution on GCP for campaign/ad analytics (ingest doubleclik and other ad-server data into DW). Data is ingested as batch, with star schema but will have updates trickling in for up to a week, need trend analysis for multiple clients (advertisers) and reporting. I can't decide between Google Big table which supports updates and timeseries analysis Vs Big Query which is ideal for star schema and ad-hoc analysis.
Any suggestions? Performance and flexibility are important.
