Super well! I don't work without this tool running in the background supervising all the agents' work

I've been building https://roborev.io/ (continuous background code review for agents) essentially as a cope to supervise the poor quality of the agents' work, since my agents write much more code than I can possible review directly or QA thoroughly. I think we'll see a bunch of interesting new tools to help alleviate the cognitive burden of supervising their work output.

I was especially excited to learn that RZ is built on Apache Arrow internally, which makes it easy to integrate with other Arrow-based applications and the emerging "Composable Data Stack". Really exciting stuff, they're just getting started!

If you read my slide decks over the last 7 years or so (while I've been working actively on Arrow and sibling projects like Ibis) I've been saying exactly this.

See e.g. https://ibis-project.org/

Almost no database systems support multidimensional arrays. So they are not appropriate for many use cases?

* BigQuery: no * Redshift: no * Spark SQL: no * Snowflake: no * Clickhouse: no * Dremio: no * Impala: no * Presto: no ... list continues

We've invited developers to add the extension types for tensor data, but no one has contributed them yet. I'm not seeing a lot of tabular data with embedded tensors out in the wild.

I challenge you to have a closer look at the project.

Deserialization by definition requires bytes or bits to be relocated from their position in the wire protocol to other data structures which are used for processing. Arrow does not require any bytes or bits to be relocated. So if a "C array of doubles" is not native to the CPU, then I don't know what is.

> Arrow's serialization is Protobuf

Incorrect. Only Arrow Flight embeds the Arrow wire format in a Protocol Buffer, but the Arrow protocol itself does not use Protobuf.

There's no serde by design (aside from inspecting a tiny piece of metadata indicating the location of each constituent block of memory). So data processing algorithms execute directly against the Arrow wire format without any deserialization.

Microsoft is also on top of this with their Magpie project

http://cidrdb.org/cidr2021/papers/cidr2021_paper08.pdf

"A common, efficient serialized and wire format across data engines is a transformational development. Many previous systems and approaches (e.g., [26, 36, 38, 51]) have observed the prohibitive cost of data conversion and transfer, precluding optimizers from exploiting inter-DBMS performance advantages. By contrast, inmemory data transfer cost between a pair of Arrow-supporting systems is effectively zero. Many major, modern DBMSs (e.g., Spark, Kudu, AWS Data Wrangler, SciDB, TileDB) and data-processing frameworks (e.g., Pandas, NumPy, Dask) have or are in the process of incorporating support for Arrow and ArrowFlight. Exploiting this is key for Magpie, which is thereby free to combine data from different sources and cache intermediate data and results, without needing to consider data conversion overhead."

(Wes here) I appreciate the Arrow shout-out but note that Apache Arrow has been a major open source community collaboration and not something I can take sole credit for.

There is no “JIRA politics” blocking the LZ4 work, only a lack of volunteers to do the development and testing.

Keep in mind that Arrow Java<->C++/Python interop has been in production use in Apache Spark and elsewhere for multiple years now. We have avoided some of the mistakes of past projects by really emphasizing protocol integration tests across the implementations.
