Research direction
Start with the provided Kudu dimension-table DDL and reproduce the join against d_goods_wlm_sku_rel. Inspect the resulting rows and determine whether duplicates come from the join semantics, source keys, or caching configuration. Done means the expected join result contains no unintended duplicate records, but the issue needs a query and expected output before work can begin.
