> Project: Spark
> Issue Type: Task
> Components: Connect, Structured Streaming
> Affects Versions: 3.5.0
> Reporter: Peng Zhong
> Assignee: Raghu Angadi
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.5.0

>
> Add support in Spark Connect to cache a DataFrame on server side. From client
> side, it can create a reference to that DataFrame given the cache key.
>
> This function will be used in streaming foreachBatch(). Server needs to call
> user function for every batch which takes a DataFrame as argument. With the
> new function, we can just cache the DataFrame on the server. Pass the id back
> to client which can creates the DataFrame reference. The server will replace
> the reference when transforming.
