Atish, ExtractText has a setting called Max Buffer Size that defaults to 1 MB, but I don't think this is causing your queue to build up before Extract Text. While I don't know the exact details of your flow, I suggest you try Split Text instead of Split Content, as this is a more commonly used pattern.
An example template is available on the NiFi dev page: https://cwiki.apache.org/confluence/display/NIFI/Example+Dataflow+Templates CsvToJSON.xml <https://cwiki.apache.org/confluence/download/attachments/57904847/CsvToJSON.xml?version=2&modificationDate=1486479474000&api=v2> This flow shows how to convert a CSV entry to a JSON document using ExtractText and ReplaceText. If you upgrade to 1.3, you can use the NiFi schema registry to convert formats. Here is a great write up: http://bryanbende.com/development/2017/06/20/apache-nifi-records-and-schema-registries Thanks, Lee On Wed, Jul 12, 2017 at 11:24 AM, Atish Ray <[email protected]> wrote: > Thanks!!!
