as you said, you can try to put your data in SET first. If you don't store it, it means that the data is in SET, so don't execute the push command.
otherwise, consider using lua to do the above, and then provide it to the caller as an instruction.
1. The data entered by set is orderly and non-repetitive, so there is no repetition
2. Delete the data in the collection after each successful execution
3. If the execution fails, store the failed data in another collection and use multiple threads to process Synchronize
list, first lrem and then push
