Hello community, I have currently every ~5 days the problem that FlowFiles from the Wait Processor are not get released, only after the "Expiration Duration" was reached (and then routed to the expired relationship). The DistributedMapCacheClientService/DistributedMapCacheServer is used and the problem was prevalent in 1.17/1.20/1.21. After restarting Nifi everything is working fine again with new arrived flowfiles, except that the old flowfiles are still hanging in the wait relationship. Has anyone also experienced the same problem or know what the problem could be? Thank you!

Hello, could you please check right before UpdateAttribute Processor, if the attribute "name" is filled with your expected content? Normally it is correct what you explain - maybe you loose somewhere after merge, wait/notify, ... your attribute. Greetings

Hello, the problem you have with the merge is that your property "Merge Strategy" needs to be set to "Defragment" after that it should work if both flowfiles also have the same fragment.identifier set. To merge those pdfs Im not 100% sure how it can be easily done, but one solution would be to set also the property "Merge Format" to tar/zip of your MergeContent processor and do it later via script unpack and merge together. Greetings

Hello, you can use after you received the result from your SQL-Database the ConvertRecord Processor to convert from Avro (Reader) to CSV (Writer). That should handle your question to do it without some Script. Greetings

Hello @Manimaran, to help you it would be good if you go a bit more specific into your question with some sample content and what you want to have as expected output. Greetings
