+
+The Rust implementation of [Apache Arrow] has just released version `9.0.0`.
+
+While a major version of this magnitude may shock some in the Rust
+community to whom it implies a slow moving 20 year old piece of
+software, nothing could be further from the truth!
+
+With regular and predictable bi-weekly releases, the library continues
+to evolve and `9.0.0` is no exception. Some recent highlights
+
+
+# `parquet`: async, performance, safety and nested types
+
+The parquet `9.0.0` release includes an `async` reader (TODO link to rustdoc
+when published), a long time requested feature. Using the `async`
+reader it is now possible to read only the relevant parts of a parquet
+file from a networked source such as object storage. Previously the
+entire file had to be buffered locally. We are hoping to add a `async`
+writer in a future release and would love some
+[help](https://github.com/apache/arrow-rs/issues/1269).
+
+It is also significantly faster to read parquet data (up to
+[60x](https://github.com/apache/arrow-rs/pull/1180#issuecomment-1018518863)
+in some cases) than with previous versions of the `parquet`
+crate. Kudos to [tustvold](https://github.com/tustvold) and
+[yordan-pavlov](https://github.com/yordan-pavlov) for their
+contributions in these areas.

Review comment:
       As a starting point, I am hoping to add 8 Raspberry Pi nodes shortly. I am considering adding some more powerful hardware as well, perhaps a Mac Mini.
