This solved the crashes, though there was no performance improvement from having these run in parallel. Difficult to say from here if this is a Python GIL or SQL contention issue.

(GSFC-618.0)[SCIENCE SYSTEMS AND APPLICATIONS INC] a écrit : How can I “open” a handle to a pre-existing memory dataset? That sounds like it may work for me. If it is a dataset from the "Memory" driver, no. Otherwise you could for example create a GeoPackage (or shapefile... if you don't want to hit any SQLite locking) as a /vsimem/ file and open it as many times as wished. -- http://www.spatialys.com<http://www.spatialys.com/> My software is free, but my time generally not. Butcher of all kinds of standards, open or closed formats. At the end, this is just about bytes.
