> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.4.0
> Reporter: Hyukjin Kwon

> Priority: Major
> Labels: pull-request-available
>
> A follow-up to SPARK-60101 (https://github.com/apache/spark/pull/59424) and
> SPARK-60723. Native data sources cannot limit the data of a micro-batch of a
> streaming read, such as a maximum number of rows for each micro-batch, which
> the guide lists as a limitation of version 1 of spark_datasource.h. Add
> admission control within version 1: a capability SPARK_DS_ADMISSION_CONTROL,
> a function default_read_limit appended to SparkDsLibrary, and the read limit
> and, for Trigger.AvailableNow, the end of the run appended to
> SparkDsLatestOffsetInfo.
