mistercrunch opened a new pull request #5424: Avoid expensive select_star on dashboard bootstrap data
URL: https://github.com/apache/incubator-superset/pull/5424
 
 
   The dashboard page bootstrap data currently attempts to generate the
   `SELECT` statement with column name details for each table represented
   in the dash. This means it calls the database(s) and waits for column
   details prior to returning any HTML.
   
   This makes the default select_star property generate a simple
   `SELECT *` with no column details instead, which doesn't require
   interogating the DBs.
