Loading a trillion rows of weather data into TimescaleDB
Summary: In a blog post, Ali Ramadhan explores building a weather data warehouse using PostgreSQL and TimescaleDB. The goal is to analyze historical weather data for signals of climate change. The data used is the ERA5 climate reanalysis product, which provides an estimate of the Earth's weather. Ramadhan tests various methods to load the data into the database, including single-row insert, multi-valued insert, and copy statement. The fastest method is using psycopg3 to directly copy data into a hypertable. The post also discusses parallelization and tweaking Postgres settings for faster inserts.
