What is MotherDuck?

MotherDuck adds who-can-open controls to Dives and a SQL view of compute usage.

MotherDuck ships a weekly changelog. The November 12 release lets owners keep a Dive private or share it with roles, users or the whole organization, with matching GRANT READ ON DIVE commands; new Dives start private. Flight run access can now be managed in the UI, and Business plans can query hourly Duckling usage per user from MD_INFORMATION_SCHEMA.COMPUTE_USAGE. It lands a week after the redesign that put Agent Chat on the home screen.

What is Fluent Bit?

Fluent Bit 5.2 adds its own typed scripting language for log processing

Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.

MotherDuck adds who-can-open controls to Dives and a SQL view of compute usage.

◆ Current state

MotherDuck ships a weekly changelog. The November 12 release lets owners keep a Dive private or share it with roles, users or the whole organization, with matching GRANT READ ON DIVE commands; new Dives start private. Flight run access can now be managed in the UI, and Business plans can query hourly Duckling usage per user from MD_INFORMATION_SCHEMA.COMPUTE_USAGE. It lands a week after the redesign that put Agent Chat on the home screen.

◆ Where it's heading

The agent-first redesign made Dives and Flights the things people create; the releases since are about controlling who sees and runs them and what they cost. Governance that began with row- and column-level security in October now covers the agent-built objects too.

◆ Prediction

Next likely are finer controls on what Agent Chat can do on a user's behalf, or usage limits built on the new compute usage view, since both follow from the permissions and cost work in the last two releases.

Fluent Bit 5.2 adds its own typed scripting language for log processing

◆ Current state

Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.

◆ Where it's heading

After a month of hardening on 5.1, the 5.2 line puts new surface on top: a typed transform language that also runs in the browser build. Fluent Bit is moving from a collector configured with Lua snippets toward an agent with its own checked policy format.

◆ Prediction

Expect 5.2.x patch releases soon fixing regressions in the new FTS processor, and more FTS policy packs; the browser SDK is likely to stay labelled experimental for now.
