Hi! I have flows on NIFi and in many places, I have to save data to the database. I mainly use PutSql or PutdatabaseRacord processors. So far, everything was working fine, but today we wanted to test our data and issued 15 messages at once. Unfortunately, in several places, during data saving or updating, an error appeared - error.code 1205 error.message Transaction (Process ID 76) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. error.sql.state 40001 - after which some data was saved or updated correctly, others unfortunately were not. How can I resolve this situation, and how can I protect myself against something like this?   ... View more

Additionally, I need each record to have a common part: messageId, markerId, dateFrom and dateTo Is it possible to do something like that with jolt transformation? ... View more

Hi i have problem with NIFI-I download json records from Kafka, I split to have single records-here i have round robin strategy, I add attributes, then I give the id attribute and divide the flow into two paths, on one I do some actions with invokes http to reach some data and transform it to attributes, I add attributes, clear the context and I would like to merge it back to keep these jsons from one paths and attributes on the other. I use the merge content processor for this, merging using the id attribute that I assigned at the beginning. And now I have a problem because it works, but in the case of a larger number of records, e.g. 200, it doesn't because I have an error BIN_MANAGER_FULL. Minimum Number of Entries is 2 and Maximum Number of Entries is 2, while Maximum number of Bins is 10 and I would not like to increase it. Is there any way to bypass this and make it work for a larger number of records? For example, apply a limit so that it merges only when there is space or divede content and wait? I have no idea how to reslove this problem. ... View more
