William1104 commented on issue #24221: [SPARK-27248][SQL] refresh table should recreate cache with same cache name URL: https://github.com/apache/spark/pull/24221#issuecomment-479560769 Hi @gatorsmile, thanks for the review. * May I know where the migration guide? I am happy to update related session. * A newly added test ‘Refresh Qualified Table’ would fail with the old behavior. The old behavior would recreate cache with unqualified name upon table refresh. This test was added to verify the new behavior. * Yes. You are right that we should add a test to sql/core. I will checkout related test cases in sql/core to learn a bit more on that. * it seems that we missed a test utility to create a cache with non temp table and clean them up afterward. I will creat such utility to enrich the test utilities. * I will do my best to check those cache/uncache calls. Hope I did not miss anyone. Again. Thanks for your help. Best regards, William
