> 需要讨论的一个共识是:hudi 提供给 spark 的 relationship 应该是可变的吗?目前的 relationship 是不可变的。在同一个 spark context 下,一旦建立了 relationship,spark 在某些情况下会复用这个 relationship。比如同一个查询 sql,会缓存对应的执行计划。那么同一个 relationship 就会一直被复用,查询结果也永远是相同的,即使在这些查询过程中有数据发生变化。@yuzhaojing @danny0405 @yihua -- This is an automated message from the Apache Git Service.
