Hi,
why the materialized view itself bloats. If no refresh then no bloat right? If fresh then set based delete operation will make materialized view bloat?
I also found the same question online. https://dba.stackexchange.com/questions/219079/bloat-on-materialized-views Unfortunately nobody answered...


The definition of bloat is a deleted row.  Bloat can be reduced by subsequent row insertions.
