: updates? i can't do this because i have delta-import queries which also : should be able to assign uuid when it is needed
You really need to give us a full and complete picture of what exactly you are currently doing, what's working, what's not working, and when it's not working what is it doing and how is that differnet from what you expect.
example: you mentioned you have "requesthandler with name "/update" which contains uuid update срфшт" (presumably you mean the processor) but you haven't shown us your configs, or any of your logs, so we can see how exactly it's configured, or if/how it's being used.
If UUIDUpdateProcessorFactory is in place, then it should only generate a new UUID if the document doesn't already have one -- if you are using DIH to add documents to the index, and the uuid you are using/generating isn't also the uniqueKey field, then the UUIDUpdateProcessorFactory doens't have any way of magically knowing when a "new" document is actually a replacement for an old document.
(If you are using Atomic Updates, then registering UUIDUpdateProcessorFactory *after* the DistributedUpdateProcessorFactory can help -- but that doesn't sound like it's relevant if you are using DIH detla updates)
Please review this page and give us *all* the details about your current setup, your goal, and the specific problem you are facing...
