Functions

func Start

func Start(ctx context.Context, tCache cache.TaskCache, repos repograph.Map, tcc *task_cfg_cache.TaskCfgCacheImpl, btProject, btInstance string, ts oauth2.TokenSource) error

Start initiates "average time to X% bot coverage" metrics data generation. The caller is responsible for updating the passed-in repos and TaskCfgCache.
