Hi everyone,

I have a range of a valid numbers to be used for identifying documents. Whenever I’m going to create a document, I have to select an unused number. What is the best way to implement this? Because I’m thinking I might run into race conditions if I do someting like this :

  • query latest existing document
  • select next document number based on latest document

Thanks!
