> Reporter: Ashutosh Bapat

>
> refreshPrivileges() calls listTableAllColumnGrants() to fetch the column
> level privileges. The later function retrieves the individual column objects
> by firing one query per column privilege object, thus causing the backend db
> to be swamped by these queries when PrivilegeSynchronizer is run.
> PrivilegeSynchronizer synchronizes privileges of all the databases, tables
> and columns and thus the backend db can get swamped really bad when there are
> thousands of tables with hundreds of columns.
> The output of listTableAllColumnGrants() is not used completely so all the
> columns the PM has tried to retrieves anyway goes waste.
> Fix this by using direct SQL to fetch column privileges.
