I am looking at how to have 2 engines a session. I want to be able to switch between engine used based on if any writes will be happening to the data being read. I can tell if any data will be modify by if the transaction started by issues a begin.
I want to setup a number of server doing Replication. I need to have a master and a number of slaves. In the code I always start transaction that will be doing write with begin. I would like to have the session have 2 engines. The first engine is used outside of any transaction that have not started with a begin. This would allow all reads to use a slave mysql server and keep the records in the session identify map. The second engine would be used for writes. This engine is selected in the transaction started with a begin. The rows are read with select for update. These rows also would be session identify map. When flushing modified data it need to be flushed to master. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
