Manage transactions and operations efficiently. After an initial Connect multiple databases in SQLAlchemy with separate engines and sessions for PostgreSQL and SQLite. When creating tables, SQLAlchemy will issue the SERIAL datatype for integer-based primary key columns, which generates a sequence and server side default corresponding to the column.

Recently, more and more Python applications have been built based on async communication using the asyncio library that allows a programmer to write PostgreSQL supports sequences, and SQLAlchemy uses these as the default means of creating new primary key values for integer-based primary key columns. I know this might be really a simple question but I don't know the solution. I am working on a project which uses a postgres database consisting of multiple inter-dependant schemas.
