---------------------------------
Summary: GenerateTableFetch should allow you to specify an initial
Max Value (cloned)
Key: NIFI-4282
URL: https://issues.apache.org/jira/browse/NIFI-4282
Project: Apache NiFi
Issue Type: Task
Components: Extensions
Reporter: Matt Burgess
Assignee: Matt Burgess
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.
