connections you can create an ExecutionContext. Execution contexts allow finer-grained control over managing multiple connections to the database. When an execution context is initialized (either as a context wrapped block. You can also choose whether to wrap the block in a transaction. Execution context examples: with db.execution_context() as ctx: # A new connection will be opened or, if using a connection transaction will be committed and the connection # will be closed (or returned to the pool). @db.execution_context(with_transaction=False) def do_something(foo, bar): # When this function is called,
