-**Note**: State retention defined in a [query
configuration](query_configuration.html) is not yet implemented for temporal
joins.
-This means that the required state to compute the query result might grow
infinitely depending on the number of distinct primary keys for the history
table.
+**注意**: 临时 Join中的 State 保留（在 [查询配置](query_configuration.html)
中定义）还未实现。这意味着计算的查询结果所需的状态可能会无限增长，具体数量取决于历史记录表的不重复主键个数。
-### Processing-time Temporal Joins
+### 基于 Processing-time 临时 Join
-With a processing-time time attribute, it is impossible to pass _past_ time
attributes as an argument to the temporal table function.
-By definition, it is always the current timestamp. Thus, invocations of a
processing-time temporal table function will always return the latest known
versions of the underlying table
-and any updates in the underlying history table will also immediately
overwrite the current values.
+如果将 processing-time 作为时间属性，将无法将 _past_ 时间属性作为参数传递给临时表函数。
