Package buildstats contains code to sync the coordinator's build logs from Datastore to BigQuery.
Verbose controls logging verbosity.
SyncBuilds syncs the datastore "Build" entities to the BigQuery "Builds" table. This stores information on each build as a whole, without details.
SyncSpans syncs the datastore "Span" entities to the BigQuery "Spans" table. These contain the fine-grained timing details of how a build ran.
