Summary
In this chapter, we learned about DuckDB operations and performance. We explored the features and techniques that can help optimize the speed of DuckDB. We used indexes to accelerate queries and explored effective ways to manage and examine file operations on Parquet data files.
We also explored timestamps, seeing how DuckDB represents points in time internally and how it bins them into structured timestamps, as well as the usage of time zone information. We also looked at how window functions can be used to effectively process time series data.
Our next chapter introduces some powerful extensions that are available in DuckDB and how they can be used to extend DuckDB's capabilities across a range of specialized applications.
