Loading very large data sets can take a long time and consume a lot of computing resources. How data is loaded can also affect query performance. We will discuss best practices for loading data efficiently using COPY commands, bulk inserts, and staging tables. We will also cover the key decisions that will heavily influence overall query performance. These design choices also have a significant effect on storage requirements, which in turn affects query performance by reducing the number of I/O operations and minimizing the memory required to process queries.
