NiFi processor to fetch attribute value dynamically from file or table

[Mothilal M <mo...@gmail.com>]

Hey Hi,

I want NiFi processor to fetch attribute value on run time. Example - if I
am filtering twitter feeds by specific keywords, i want to maintain the
list of keywords in a separate repository like file or table and not
confined as a text box value. In that case, how will NiFi processor fetch
that values from external file or table to attribute value.

Warm Regards,
M. Mothilal

Hi, 
i have declared  my custom properties file path  in nifi.properties  to
variable 'nifi.variable.registry.properties=custom.properties'
.i want my processors to pickup the new value of the property when the
chnages are made to a property.I have loaded the updated properties in the
code(FileBasedVariableRegistry.java).but processors takes old values..
