> Whenever following scenarios happen :
>  # Custom Datasource ( Kafka for instance ) -> Hudi Table
>  # Hudi -> Hudi Table
>  # s3 -> Hudi Table
> Following metadata need to be captured :
>  # Table Level Metadata
>  * 
>  ** Operation name ( record level ) like Upsert, Insert etc for last operation performed on the row
>  # Transaction Level Metadata ( This will be logged on Hudi Level and not Table Level )
>  ** Source ( Kafka Topic Name / S3 url for source data in case of s3 etc )
>  ** Target Hudi Table Name
>  ** Last transaction time ( last commit time )
> Basically , point (1) collects all details on table level  and point (2) collects all the transactions happened on Hudi Level
> Point(1) would be just a column addition for operation type
> Eg for Point (2) :  Suppose we had an ingestion from Kafka topic 'A' to Hudi table 'ingest_kafka' and another ingestion from RDBMS table ( 'tableA' ) through Sqoop to Hudi Table 'RDBMSingest' then the metadata captured would be :
>  
> |Source|Timestamp|Transaction Type|Target|
> |Kafka - 'A'|XXXXXX|UPSERT|ingest_kafka|
> |RDBMS - 'tableA'|XXXXXX|INSERT|RDBMSingest|
>  
> The Transaction Details Table in Point (2) should be available as a separate common table which can be queried as Hudi Table or stored as parquet which can be queried from Spark
