1. noOfUniqueDevices: This metric can be computed by filtering out records with d_period = 0 (cumulative), d_device_id = 'all' and summing up the m_total_devices_count field.
2. totalContentPlaySessions: This metric can be computed by filtering out records with d_period = 0 (cumulative), d_type = 'content', d_mode = 'play' and summing up the m_total_sessions field.
3. totalTimeSpent: This metric can be computed by filtering out records with d_period = 0 (cumulative), d_device_id = 'all' and summing up on m_total_ts field.
4. totalDigitalContentPublished: This metric can be computed from the search api. We need to use the composite search API /composite/v3/search and filter by contentType Resource to get a count of total number of live content.

The cumulative summary files will be uploaded to cloud storage using Secor. The sunbird platform team will pull the cumulative summary file from the cloud storage. There will be a new file generated everyday with the date appended to the file name.
