   A hack to get around this is to use "forced overlord/coordinator" mode. But 
that only works until a certain point.
   
   This query is what's breaking the UI.
   
   ```sql
   SELECT datasource, COUNT(*) FILTER (WHERE (is_published = 1 AND 
is_overshadowed = 0) OR is_realtime = 1) AS num_segments,
        COUNT(*) FILTER (WHERE is_available = 1 AND ((is_published = 1 AND 
is_overshadowed = 0) OR is_realtime = 1)) AS num_available_segments,
        COUNT(*) FILTER (WHERE is_published = 1 AND is_overshadowed = 0 AND 
is_available = 0) AS num_segments_to_load,
        COUNT(*) FILTER (WHERE is_available = 1 AND NOT ((is_published = 1 AND 
is_overshadowed = 0) OR is_realtime = 1)) AS num_segments_to_drop,
        COUNT(*) FILTER (WHERE ((is_published = 1 AND is_overshadowed = 0) OR 
is_realtime = 1) AND "start" LIKE '%:00.000Z' AND "end" LIKE '%:00.000Z') AS

        COUNT(*) FILTER (WHERE ((is_published = 1 AND is_overshadowed = 0) OR

        COUNT(*) FILTER (WHERE ((is_published = 1 AND is_overshadowed = 0) OR

        MAX("num_rows") FILTER (WHERE is_published = 1 AND is_overshadowed = 0)

        SUM("num_rows") FILTER (WHERE (is_published = 1 AND is_overshadowed = 
0) OR is_realtime = 1) AS total_rows,
        CASE WHEN SUM("num_rows") FILTER (WHERE is_published = 1 AND

                SUM("size") FILTER (WHERE is_published = 1 AND is_overshadowed

        ) ELSE 0 END AS avg_row_size
        FROM sys.segments GROUP BY 1 ORDER BY 1
