Does SQLAlchemy have any builtin support to execute multiple SELECT statements in a single round trip to the database, similar to NHibernate's .future() call (http://ayende.com/blog/3979/nhibernate-futures) or ActiveRecord::Futures (https://github.com/leoasis/activerecord-futures).
I came across the SQLAlchemy-Future project (http://lunant.github.io/SQLAlchemy-Future/), but it appears to just spawn a new thread for each query so it doesn't block the normal flow, instead of batching multiple queries together into a single trip. I've seen examples in SQLAlchemy on how to do this for INSERTs, but not for SELECT queries. http://docs.sqlalchemy.org/ru/latest/core/tutorial.html#executing-multiple-statements If not, it would be nice to call .future() or .promise() on instead of a ` sqlalchemy.orm.query.Query` instance instead of .all() to batch multiple queries and have them executed in a single round trip. The way NHibernate works is it will execute all the queries called with .future() when an attempt is made to access the results of one of the query's results. So if you've called .future() on 5 queries, but start to access the results from the 3 query before .future() was called on the remaining 2 queries, it will make 2 round trips. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
