Apache Uniffle vs dbt Core: at a glance
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 dbt Core?
dbt Fusion's second beta is adapter work: ClickHouse gets materializations, indexes, and catalogs
Fusion 2.0 is in its second beta, and the content has shifted from engine capability to adapter coverage. beta.2 is almost entirely ClickHouse — Dictionary materialization, index definitions, additional settings, a relation-scoped catalog macro that fixes --write-catalog, and a seed nullability fix — plus Entra bearer-token authentication for the Fabric adapter. Behind it sits the August 14 backport wave, which cut releases for 1.1 through 1.8 in a single day to deliver one deprecated-version warning.

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.

dbt Fusion's second beta is adapter work: ClickHouse gets materializations, indexes, and catalogs
◆ Current state
Fusion 2.0 is in its second beta, and the content has shifted from engine capability to adapter coverage. beta.2 is almost entirely ClickHouse — Dictionary materialization, index definitions, additional settings, a relation-scoped catalog macro that fixes --write-catalog, and a seed nullability fix — plus Entra bearer-token authentication for the Fabric adapter. Behind it sits the August 14 backport wave, which cut releases for 1.1 through 1.8 in a single day to deliver one deprecated-version warning.
◆ Where it's heading
The two ends of this project are pulling apart cleanly. Old branches are being prepared for retirement — a deprecation warning fanned across eight of them, Python 3.8 testing dropped from 1.4 through 1.6 — while Fusion accumulates the adapter breadth it needs to be a credible replacement. beta.1 proved the engine could bind without a catalog; beta.2 is the unglamorous follow-through of making a specific warehouse work properly.
◆ Prediction
Expect further beta releases filling in per-adapter gaps rather than new engine capability, and formal end-of-life notices for the branches that just took the deprecation warning.
