Site: Add blog post for iceberg-rust 0.10.0 by dannycjones · Pull Request #17032 · apache/iceberg

dannycjones · 2026-07-01T18:01:01Z

This blog post announces the 0.10.0 release of iceberg-rust (apache/iceberg-rust#2527).

The content is an AI-assisted summary. I've reviewed the content and adjusted some items that were misleading.

I've generated the blog locally and reviewed that everything renders OK.

This is currently in draft as the release candidate voting is ongoing.

@CTTY can you provide a review?

Just minor nits on a first pass. Thanks @dannycjones!

Sorry all, this draft didn't meet the right bar. Thank you all for the feedback, I've done a much deeper review of the changes mentioned and have pushed an update.

CTTY

Thanks Danny for writing up the blog!

+### Writer Improvements
+
+- **Content-defined chunking** ([#2375](https://github.com/apache/iceberg-rust/pull/2375), [#2561](https://github.com/apache/iceberg-rust/pull/2561)): CDC table properties are now respected for optimizing Parquet file boundaries


- **Content-defined chunking(CDC)**

This is more explicit, I keep thinking about change data capture when seeing "CDC" :D

I've opted to just spell it out for clarity in the new commit (about to push)

+
+### Custom Runtime Support
+
+The [`Runtime` trait](https://github.com/apache/iceberg-rust/pull/2308) can now be injected into catalogs, decoupling `iceberg-rust` from a hard tokio dependency at the catalog layer. This enables embedding in applications with custom async runtimes.


decoupling iceberg-rust from a hard tokio dependency at the catalog layer. This enables embedding in applications with custom async runtimes.

This is inaccurate, Runtime is still a struct in iceberg-rust. users can now inject a customized tokio Runtime using the runtime api, but they cannot easily plug in a customized non-tokio runtime

Thanks for calling this out, totally misunderstood.

I'm going to update it something like this:

This allows for injecting a customized Tokio runtime into the session.
For example, it is now possible to configure the thread stack size or maximum number of threads.

+
+- **Table encryption**: With the foundational encryption stack landed, the community is working toward end-to-end encrypted reads and writes
+- **Additional commit types**: Support for `RewriteDataFiles`, `RowDelta`, and `Overwrite` commit operations
+- **Extensibility**: Continued investment in abstractions for pluggable storage backends and runtime configuration


What do we mean here?

I'll remove it for now. What I had in mind was further storage trait work, such as extending to object_store. That being said, the work hasn't started so I'll omit it for this post.

dannycjones · 2026-07-21T10:40:42Z

Thanks all, iceberg-rust 0.10.0 is now out! I've updated the post. It should be ready to merge, pending addressing any review feedback.

kevinjqliu

LGTM!

This looks great, thank you! Please LMK if theres any other edits before we can merge this 😄

Renders perfectly!

mbutrovich · 2026-07-27T17:42:05Z

Do we want to wait for 0.10.1 at this point?

dannycjones · 2026-07-27T17:45:13Z

Do we want to wait for 0.10.1 at this point?

I was wondering the same. Personally, I don't think so, however I'm also happy to make a few small changes if needed and ship it once 0.10.1 is out (if the patch is needed for the crates).

If we do wait for 0.10.1, my thinking would be to make it a "0.10" blog post rather than "0.10.0", especially since that's the cadence we're more interested in.

Let me know what you think, I'm happy with either outcome.

kevinjqliu · 2026-07-27T22:35:00Z

Do we want to wait for 0.10.1 at this point?

I dont think we necessary have to wait... the rust crates are available already. 0.10.1 is just fixing pyiceberg-core on the pypi side.

I'd like to move forward, this has been opened for a while 😄

dannycjones · 2026-07-28T08:02:55Z

Sounds good to me, let's ship!

mbutrovich · 2026-07-28T11:41:16Z

I dont think we necessary have to wait... the rust crates are available already.

Sounds good, I misread the email chain and thought crates had an issue and were pulled as well.

CTTY

LGTM overall! Just one minor comment
