@vkuznetsov  - As a workaround, can you please try converting the streaming table to a regular table using a stand-alone/periodic job and use it for Delta sharing? 

spark.readStream.table("<streaming-table>")
	.writeStream
	.option("checkpointLocation", "dbfs:/checkpoints/checkpoint_bar_1")
	.partitionBy("<partition-column>")
	.toTable("<delta-table>")
