-Compared to a regular join operation, this kind of join only supports
append-only tables with time attributes. Since time attributes are
quasi-monotonic increasing, Flink can remove old values from its state without
affecting the correctness of the result.
+与常规 Join 操作相比，时间窗口 Join 只支持带有时间属性的递增表。由于时间属性是单调递增的，Flink
可以从状态中移除过期的数据，而不会影响结果的正确性。
-Join with a Temporal Table Function
+临时表函数 Join
--------------------------
-A join with a temporal table function joins an append-only table (left
input/probe side) with a temporal table (right input/build side),
-i.e., a table that changes over time and tracks its changes. Please check the
corresponding page for more information about [temporal
tables](temporal_tables.html).
+临时表函数 Join
连接了一个递增表（左输入/探针侧）和一个临时表（右输入/构建侧），即一个随时间变化且不断追踪其改动的表。请参考[临时表](temporal_tables.html)的相关章节查看更多细节。
-The following example shows an append-only table `Orders` that should be
joined with the continuously changing currency rates table `RatesHistory`.
+下方示例展示了一个递增表 `Orders` 与一个不断改变的汇率表 `RatesHistory` 的 Join 操作。
-`Orders` is an append-only table that represents payments for the given
`amount` and the given `currency`.
-For example at `10:15` there was an order for an amount of `2 Euro`.
+`Orders` 表示了包含支付数据（数量字段 `amount` 和货币字段 `currency`）的递增表。
+例如 `10:15` 对应行的记录代表了一笔 2 欧元支付记录。
