I have specified an inclusion list of 23 tables in the data model to scan and identify relationships while the schema contains over 47K tables. I would expect TDM Portal to scan only those 23 tables but instead it scanning the entire database which has already returned more than 76K tables and still continuing. I believe it is scanning the entire database.
The database is Oracle 19c and TDM Portal is 4.9.416.0
Release : 4.9.1
Component : Web Portal - Data Modeling
There are two stages during Model scan:
Stage 1: to discover all tables and views present in the specific schema
stage 2: using the filter that only includes 23 tables perform column, index, primary, physical relationship and logical discovery
Stage 1 does NOT take long ... okish with 76K
stage 2 on the other hand will take time if the list is long. In this, there are 23 tables
This particular schema has a lot of views, hence the high discovered objects.
