@MilanTyagi2004 我昨天提供的信息有偏差. isValid 函数在使用侧没有被调用. 但isValid 的判断逻辑在使用侧是用到了的. 1. org.apache.doris.nereids.stats.StatsCalculator#checkNdvValidation 如果 ndv inValid 就不做 join reorder 2. org.apache.doris.nereids.stats.StatsCalculator#getColumnStatistic(org.apache.doris.catalog.TableIf, java.lang.String, long) 最后 1236 行,如果 ndv 不合法,就将 columnstats 转为 unknown -- This is an automated message from the Apache Git Service.
