What is Rivet?

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

What is Apache Arrow Rust?

Arrow Rust cuts release candidates on three older lines at once.

Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.

7.5

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

◆ Current state

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

◆ Where it's heading

Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.

◆ Prediction

Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.

A5.0

Arrow Rust cuts release candidates on three older lines at once.

◆ Current state

Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.

◆ Where it's heading

The project keeps four major lines alive and patches them together, so downstream users on older Arrow versions still get fixes. Feature work stays on the 60 line.

◆ Prediction

Expect the three patch releases to publish after the vote period, and a 60.2.0 or 61.0.0 candidate to follow.
