Thanks for getting back to me. I’m using a Postgresql database in the OMOP v5 format. I have access to both a smaller and a larger dataset. In the smaller database, the cohort sizes are ~1K and ~1.2K for the target and comparator groups. I was successfully able to run getCohortMethodData on this database, but the full execution ran for 21 days. I also have access to a larger database where my cohorts are ~26K and ~33K patients respectively. So quite big! And I’d like to avoid that analysis taking 3 weeks if possible. My original hypothesis that it might be something to do with the feature extraction - perhaps there’s a dependency that I need to update?
I’m also accessing the database on a share computing cluster, so I don’t think I can increase the RAM, but it should have enough disk to complete the queries.
Thanks again for your thoughts, and if others have ideas, I’d very much appreciate it.
