> Key: SPARK-61284
> URL: https://issues.apache.org/jira/browse/SPARK-61284
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Gengliang Wang
> Priority: Major
> Labels: pull-request-available
>
> A batch write of a native data source closes its writer handle right after a
> successful commit, and after an abort (NativeDataSourceWriter). A streaming
> write does not: NativeDataSourceStreamWriter.commit and abort leave the
> handle open, and NativeStreamWriters.register closes it only when the query
> creates the stream writer of its next micro-batch, after create_writer of
> that micro-batch, or, for the last micro-batch of a query, once the handle is
> no longer referenced. A library that releases an exclusive resource in
> close_writer, such as a lock on its destination, then fails or blocks at the
> second micro-batch.
> Close the handle of a stream writer after a successful commit and after an
> abort, as for batch writes, so that NativeStreamWriters only closes the
> stream writers that never finish, and update the lifecycle that
> spark_datasource.h documents.
