GIS Day 2021 - Python Multithreading: Speed up your Scripts 1000% (Geocoding Example)

Python is not internally thread safe and utilizes a global interpreter lock (GIL) to synchronize code execution. The GIL restricts python to a single thread on a single core preventing sequential scripts from utilizing the full processing power of modern multicore computers. I/O and CPU bound processes are common in GIS processing and can drastically benefit from concurrency. Examples include large file transfers, geocoding, or raster processing. This talk will cover utilizing a web based geocoder and concurrency to quickly convert a list of addresses to GPS coordinates.
