Haiyang Sun resolved SPARK-56284.
---------------------------------
Resolution: Implemented
> Key worker abstraction for language-agnostic UDF protocol
> ---------------------------------------------------------
>
> Key: SPARK-56284
> URL: https://issues.apache.org/jira/browse/SPARK-56284
> Project: Spark
> Issue Type: Sub-task
> Components: Connect, Spark Core
> Affects Versions: 4.2.0
> Reporter: Haiyang Sun
> Priority: Major
> Labels: pull-request-available
>
> To enable language-agnostic UDF execution in Spark, a key step is to decouple
> the Spark engine from language-specific worker runtimes and define a unified
> interaction model between Spark and those workers.
>
> As a first step, this ticket focuses on establishing the core abstractions
> for describing worker specifications, as well as the primary interfaces Spark
> will use to interact with workers.
>
> This initial step will primarily introduce a new build target/module to host
> these abstractions. Concrete implementations of the abstractions (e.g., for
> specific languages or execution backends) will be introduced in follow-up
> tasks.
