[basex-talk] pre values and add-only dbs

Dear all at BaseX,

Can pre values change in add-documents-only databases ?

Can pre values change in add/delete-documents-only databases ?

Here is the big picture : I have a Document DB, references by a Index DB which stores (key,pre) couples, Where pre are pre values in the Document DB. Document DB documents are only added (or sometimes deleted). Do I have to use id values or can I use pre values ?

Best regards
