> Need to populate the flow_activity table
> -Stores per day flow run pointers and info
> -Written to by RM’s collector for application lifecycle
> primary key: cluster ! day timestamp ! user ! flow id
> -For the day timestamp we can take the millis since epoch for the end of the
> day (24:00h).
> columns include runids, start time, end time, snapshot time
> -This table will also be used to efficiently retrieve the flows that had an
> activity in a certain day. That is needed for daily aggregations, but also
> for several UIs, including a flow-based UI.
