             Summary: Time Travel (querying the historical versions of data) 
ability for Hudi Table
                 Key: HUDI-1460
                 URL: https://issues.apache.org/jira/browse/HUDI-1460
             Project: Apache Hudi
          Issue Type: New Feature
          Components: Common Core
            Reporter: qian heng


Hi, all:
We plan to use Hudi to sync mysql binlog data. There will be a flink ETL task 
to consume binlog records from kafka and save data to hudi every one hour. The 
binlog records are also grouped every one hour and all records of one hour will 
be saved in one commit. The data transmission pipeline should be like -- binlog 
-> kafka -> flink -> parquet.

After the data is synced to hudi, we want to querying the historical hourly 
versions of the Hudi table in hive SQL.

Here is a more detailed description of our issue along with a simply design of 
Time Travel for Hudi, the design is under development and testing：

We have to support Time Travel ability recently for our business needs. We also 
have seen the [RFC 
07|https://cwiki.apache.org/confluence/display/HUDI/RFC+-+07+%3A+Point+in+time+Time-Travel+queries+on+Hudi+table].
Be glad to receive any suggestion or dicussion.
