Hi,
I am working on a database design that I am required to use lots of tables
with one-to-many relationship. As a consequence of the design, I need to
insert thousands of entries. I tried session.add(), session.merge, however
none of them is fast enough for me to meet the requirements. I was wondering
if you can suggest me an efficient way through either ORM or ORM+Core.
Thanks!
I recently did a presentation structured around getting fast bulk inserts
with SQLAlchemy. You may find it useful:
https://speakerdeck.com/rwarren/a-brief-intro-to-profiling-in-python
Please note that the focus was on profiling, and not on SQLAlchemy. The
SQLAlchemy example just worked out well (with a contrived step or two) as a
vehicle for showing different profiling steps/gotchas. Since the focus was
on profiling, the example is quite simple (a single user table)... but you
can easily extend on it for your one-to-many tables.
I also didn't 100% scrub the SQLAlchemy code (I threw this together in a
hurry), so no yelling at me for bad code. :)
