The params are then added using query.params(somerecord=x).
Is it

Unfortunately for our workload, we don't really know which set of gets()
are going to fire, and we can't fit the entire table into memory.
I was curious about whether passing in fields instead of tables into Query

We've been finding the SA ORM to be a large component in our
application execution time. Our application makes frequent queries,
and most of them simply query whole rows from a single table with some
filters, but no joins (therefore, very basic queries). We've found
that an alarming amount of

1. Query compilation... This
resulted in ~2x improvement.
that seems very strange - 2x improvement inthe overall speed of your
application? I've done an enormous amount of profiling - SQL compilation is
miniscule compared to the SQL statement's execution itself and the fetching

Hi,
I am using sqlalchemy through its orm layer. The basic flow of my
program is this:
1. Download about 18000 web pages and store the raw HTML in a table
