Hi, I am a beginner in Spark and currently learning the Spark source code. I have a question about the AQE rule OptimizeSkewedJoin. I have a SQL query using SMJ FullOuterJoin, where there is read skew on the left side (the case is mentioned below). case: remote bytes read total (min, med, max) 90.5 GiB [bytes:97189264140] (208.5 MiB [bytes:218673776], 210.0 MiB [bytes:220191607], 18.1 GiB [bytes:19467332173]) However, the OptimizeSkewedJoin rule does not optimize FullOuterJoin. I would like to know the reason behind this. Thanks.
