>                 URL: https://issues.apache.org/jira/browse/NIFI-4283
>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Extensions
>            Reporter: Matt Burgess
>            Assignee: Joseph Witt
>             Fix For: 1.4.0
> NIFI-2583 added the ability (via dynamic properties) to specify initial Max 
> Values for columns, to enable the user to "pick up where they left off" if 
> something happened with a flow, a NiFi instance, etc. where the state was 
> stored but the processing did not complete successfully.
> This feature would also be helpful in GenerateTableFetch, which also supports 
> max-value columns.
> Since NIFI-2881 adds incoming flow file support, it's more useful if Initial 
> max values can be specified via flow file attributes. Because if a table name 
> is dynamically passed via flow file attribute and Expression Language, user 
> won't be able to configure dynamic processor attribute in advance for each 
> possible table.
> Add dynamic properties ('initial.maxvalue.<max_value_column>' same as 
> QueryDatabaseTable) to specify initial max values statically, and also use 
> incoming flow file attributes named 'initial.maxvalue.<max_value_column>' if 
> any.
