<p>In this post, we explained how index structures are stored in Apache
Parquet, how to embed user-defined indexes without changing the format, and how
to use user-defined indexes to speed up query processing.</p>
<p>Parquet-based systems can achieve significant performance improvements for
almost any query pattern while still retaining broad compatibility, using
user-defined embedded indexes, external indexes<sup><a

rather than proposing new file formats and reimplementing existing features.
