ETL (Extract, Transform, Load) is the industry term for importing data from external sources into a database. However, more often the pattern is ELT - Extract, Load, Transform. This talk covers methods of loading external data into PostgreSQL and reshaping it to fit local needs. The talk addresses popular commercial tools, but focuses mostly on custom coding, specifically: *) Identifying bottlenecks *) Tuning for specific optimization goals (speed, lower resource usage, etc) *) temp tables *) foreign data wrappers *) COPY from PROGRAM *) index management *) filtration techniques *) data validation and error reporting *) importing highly variant data sources
