Specify how you handle timezone normalization, large-table performance (indexes, partitioning) and null events.

Compare a frequentist approach versus a Bayesian approach for this use case, explain how you would set informative priors from historical data, and outline steps to implement a Beta-Binomial Bayesian estimator. Discuss how you would present posterior distributions and decision thresholds to non-technical stakeholders.
