A full content repository will howvere impact the overall performance of your NiFi dataflows. Because when you change nifi.content.repository.archive.enabled to false, in a cluster of 3 nodes, for example, nifi only raises 2 nodes, always the first one that starts and the second, that remains visible in the cluster, but the third , is left running only as a 1-1 clusterer ...

@mburgess Helpful information shared. I am using Nifi 1.7.1 For my case, the incremental fetching does not seem to work correctly. All records gets ingested from the database but do not make it all the way to the destination. Processor used is GenerateTableFetch then Execute SQL and the other corresponding processors down the data processing flow. Record id is captured correctly on the GenerateTableFetch property state and its up to date as the record id from the  source (db). However, it will still miss some records when processing the files making the number of records on the destination out of sync with the source from the db. Am i missing something, Would scheduling times for fetching help and how can I do that? ... View more

Thanks Matt for your view on this,the ask is to generate a batchid which should be a sequence number, so whenever querydb processor fetches records from source db (sqlserver) a batchid should be added to the flowfile so that all records have a same batchid when loaded to target table,this will help in auditing of records.but here in cluster mode it seems difficult to achieve this using updateattribute processor.i liked your idea of appending node hostname with the sequence but if i could generate atomic values across all nodes it would be much better. ...

@Matt Clarke,@matt burgess Exactly the second point is happening, each node is generating its own value incrementing from last value it has stored in its local state. So which processor or method should i use to generate an incremental batchid (batch1,batch2...so on) since update attribute is messing values when running on cluster. or is there any property by which updateattribute processors on all nodes can pickup each others's last state variable?..please suggest ...

Thanks for the solution, but since i am not familiar with rest api, solution by Matt looks easy to me. Will surely try yours one too. ... View more

Hi @Andrew Lim , Thanks for a detailed explaination.

I too faced the same issue of not receiving emails,although configuration was set as mentioned in the above article,then i added this property in botstrap-notification.xml and it worked for me. since my smtp didnt require any username and password authentication, i deleted those properties and added this one, <property name="SMTP Auth">false</property> (note this needs to be added additionally its not already there in default xml, need to false it as its default value is true (reference:https://github.com/apache/nifi/blob/master/nifi-bootstrap/src/main/java/org/apache/nifi/bootstrap/notification/email/EmailNotificationService.java) please vote up if my answer helped. ...
