Subject Re: Question with ExtractText Processor

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:
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
Here is a great write up:
