@Anil Reddy Since you don't know where in the content these four fields will fall, I would suggest using the following: The other regex rules I provided expect address as the last field. these will work no matter where in the content these patterns are found. The .*&firstname=(.*?)&.* will not work in all cases since it expect you to have 1 or more characters followed by "&filename=" followed by a many characters up to the last found "&" followed by 1 or more trailing characters. This expression will not work should firstname be the first or last field in the content. Thank, Matt If you found my answers helpful to your question, please mark it as "accepted" ... View more

@Anil Reddy You can get rid of capture group 0 by changing the "Include Capture Group 0" property to false. Capture groups are defined using (). what falls between them is a capture group. You can create a single java expression that has multiple capture groups. So the ExtractText processor creates a attribute for each of these capture groups. Then the complete result of the regular expression is assigned to the property name you created. In the above i have created four different java regular expressions. Each runs against the content of the incoming FlowFile. Each Regex has one capture group (.*?). As result you will have address.1= to that one defined capture group. NiFi also wants to create the attribute as you defined with just "address". so the <propertyname>.num attributes are created because of the use of capture groups in your regex. For example, let assume the firstname property had the following regex: firstname=(.*?)[&]{1}lastname=(.*?)[&]{1} Here you see i have two capture groups in one regular expression. This would translate in to two new attributes on your flowfile: Thanks, Matt ... View more

@Gaurav Jain NiFi does not redistribution of FlowFiles at this time between nodes behind the scenes. Any redistribution of FLowFiles between nodes in a cluster has to be done programmatically through your dataflow design via components (processors like postHTTP to ListenHTTP or RPG) to push FlowFiles to other nodes.
