No mention of schemas.

   Is there any practical limit on the number of schemas in a database?

   Will the number of schemas in a user's search path impact performance?

    Real-time CDC is the difficult part.  ora2pg (using views) can do a static migration.  No coding (unless you consider clever use of bash to modify config files to be coding).  I used it to migrate a 7TB db to Postgresql.

        Hi,

        Hope everyone is fine.

        Can someone help or guide regarding Open Source tools for Oracle to PostgreSQL migration with real time CDC. along with this is there any possibility to change the structure of the database? Let me explain a little more,

        We have an Oracle DB which is around 1TB and we want to migrate to PostgreSQL that have a new table structure, so we want to perform data transformation and real time CDC from Oracle to PostgreSQL. Do we have any good open source tool to achieve this with No Coding involved.??

        Thanks.
