Eric Fu updated SPARK-24932: ---------------------------- Description: In issue SPARK-19140 we supported update output mode for non-aggregation streaming queries. This should also be applied to streaming join to keep semantic consistent. PS. Streaming join feature is added after SPARK-19140. When using update _output_ mode the join will works exactly as _append_ mode. However, for example, this will allow user to run an aggregation-after-join query in update mode in order to get a more real-time result output. was: In issue SPARK-19140 we supported update output mode for non-aggregation streaming queries.
