+I am extremely excited to announce that [Apache DataFusion] [43.0.0] is the
+fastest engine for querying Apache Parquet files in [ClickBench]. It is faster
+than [DuckDB], [chDB] and [Clickhouse] using the same hardware. It also marks
+the first time a [Rust] based engine holds the top spot, which has previously
+been held by traditional C/C++ based engines.

+Best in class performance on Parquet is now available to anyone. DataFusion’s
+open design lets you start quickly with a full featured Query Engine, including
+SQL, data formats, catalogs, and more, and then customize any behavior you
need.
+I predict the continued emergence of new classes of data systems now that
+creators can focus the bulk of their innovation on areas such as query
+languages, system integrations, and data formats rather than trying to play
+catchup with core engine performance.
+
+ClickBench also includes results for proprietary storage formats, which require
+costly load / export steps, making them useful in fewer use cases and thus much
+less important than open formats (though the idea of use case specific formats
+is interesting[^2]).
+
+This blog post highlights some of the techniques we used to achieve this
+performance, and celebrates the teamwork involved.

Review Comment:
I certainly was inspired by the comment to help me focus where I spent my
time reviewing PRs and helping push them through, though it is a good point
that this may imply it motivated others as well, when I don't really know what
did.
Perhaps we could rephrase the motivation with something like this?
"Performance has long been a focus for DataFusion: one of the core benefits
of DataFusion is its core performance, which both excites contributors and
attracts users. There seems to have been a renewed focus on performance
recently, including a call in July 2024 from Mehmet ....?
