>
> Whenever a view is dropped, MetaDataEndPointImpl.findChildViews() checks
> whether it has child views or not. This is doing a full scan in all the rows
> in SYSTEM.CATALOG which reduces performance. When the number of rows is very
> high, it causes timeout. The check has to be done only for the tables.
