*Temporal(dynamic) Table*: Temporal table is a table that evolves over time as known as Flink *dynamic table <https://ci.apache.org/projects/flink/flink-docs-stable/dev/table/streaming/dynamic_tables.html#dynamic-tables--continuous-queries>*, rows in temporal table are associated with one or more temporal periods, all Flink tables are temporal(dynamic) table.
*Version:* A dynamic table can split into a set of versioned table snapshots, the *version* in table snapshots represents the valid life circle of rows, the start time and the end time of the valid period can be assigned by users. Temporal table can split to versioned table and regular table according to the table can tracks its history version or not. *Versioned table*: If the row in dynamic table can track its history changes and visit its history versions, we called this kind of dynamic table as versioned table. *Regular table**:* For regular table, the row in dynamic table can only track its latest version. The table in lookup join can only track its latest version it's also a regular table. https://wiki.apache.org/confluence/display/FLINK/FLIP-132+Temporal+Table+DDL+and+Temporal+Table+Join 供参考。 悟空 <[email protected]> 于2021年10月31日周日 上午10:09写道： > 我的理解是时态表和版本表是一个类似概念 并且都是动态表的一种。最好还是看下flink 官网的解释更权威下 > > > > 发自我的iPhone > > > ------------------ 原始邮件 ------------------ > 发件人: guanyq <[email protected]> > 发送时间: 2021年10月31日 09:24 > 收件人: user-zh <[email protected]> > 主题: 回复：Flink Sql表概念 > > > > 请大佬指导下： > 动态表 > 时态表 > 版本表 > 这三个是什么关系？ > flinksql里面还有其他一些表的概念么？
