Well the only advise I can give you is to write your processor and see what errors you have and come back with them. Nobody can write your processor if only you know your requirements. What I can suggest you though, is to have a look at the following examples, as they might assist you with what you are trying to achieve: https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-1/ta-p/248922 https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-2/ta-p/249018 https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-3/ta-p/249148   ...

@charliekat, this discussion is far from easy and most likely it will be a quite general one, with no specific answer to your question 🙂 There are plenty of things you could monitor and automate, starting from the CPU Usage, RAM Usage, CPU and RAM Temperature, I/O on your SSD, network packages and so on. Directly from NiFi you won't be able to perform many tasks, as it was not created for such things. However, if you are good enough with PowerShell (Gamer=Windows in 95% cases) you can create some scripts and execute them directly in NiFi. Now, depending on your script Output, you will call other scripts which will perform the desire action: like killing long running processes, or processes which are consuming to much CPU while you are gaming and so on. These actions only represent around 5-10% of what you can do. The other 90-95% are actually related to your hardware: GPU, OS, SSD, Mouse(DPI), Screen(resolution+frame rate), Keyboard, Ethernet Connection, CPU and the overall Cooling System, Windows Updates , Game settings, GPU Updates and so on .... and unfortunately, for these actions, NiFi won't be much of a friend 😞 Nevertheless, don't take my answer as a discouragement, but take it as an action to prove me wrong and go play with NiFi and make something amazing 🙂 ...

I managed to solve my issue using UpdateRecord with Literal Value replacement strategy. I have defined the following EL: ${field.value:toDate('dd-MMM-yy'):format('yyyy-MM-dd')} On the other hand, the avro schema remained the same, "type": "int" and "logicalType": "date". As for replacing the month letters, I have hard coded a very ugly IF-ELSE statement: ${field.value:contains('IAN'):ifElse(${field.value:replace('IAN','JAN')},${field.value:contains('IUN'):ifElse(${field.value:replace('IUN','JUN')},${field.value:contains('IUL'):ifElse(${field.value:replace('IUL','JUL')},${field.value})})}):toDate('dd-MMM-yy'):format('yyyy-MM-dd')} PS: this link helped me a lot: https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html ...
