What is Apache Uniffle?

Uniffle's remote shuffle service finally makes its fast path the default

Apache Uniffle is a remote shuffle service for Spark, MapReduce and Tez. The 0.10.0 release in September 2025 flipped the Netty-based transport (GRPC_NETTY) from opt-in to the default, promoted partition reassignment to general availability, and added partition splitting for oversized shuffle partitions. Releases before that were largely stabilization work: a dashboard in 0.9.0, log and layout cleanups in 0.9.1, and pure license housekeeping in 0.9.2.

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.

Apache Uniffle vs MotherDuck: editorial side-by-side

A0.0

Uniffle's remote shuffle service finally makes its fast path the default

◆ Current state

Apache Uniffle is a remote shuffle service for Spark, MapReduce and Tez. The 0.10.0 release in September 2025 flipped the Netty-based transport (GRPC_NETTY) from opt-in to the default, promoted partition reassignment to general availability, and added partition splitting for oversized shuffle partitions. Releases before that were largely stabilization work: a dashboard in 0.9.0, log and layout cleanups in 0.9.1, and pure license housekeeping in 0.9.2.

◆ Where it's heading

The arc runs from 'Netty is available' in 0.8.0, to 'Netty is production ready' in 0.9.0, to 'Netty is on by default' in 0.10.0 — a three-release migration off the original gRPC transport, executed conservatively. The parallel theme is huge-partition survival: reassignment and splitting both exist to stop a single skewed partition from taking down a shuffle write. Uniffle is optimizing for the failure modes of very large Spark jobs rather than for breadth of features.

◆ Prediction

The Rust shuffle server introduced experimentally in 0.9.0 is the obvious next promotion candidate, following the same available-then-default path Netty took. The release notes do not indicate a timeline.

ANALYTICS
6.3

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.
