Hi Ivan I am currently planning to implement solution, which will insert new documents each minute. Question1: does the optimize recreate complete index, or it only does some small update? Question2: if the index becomes invalid after insertion of new document, how does it affect query performance? A bit? or possibly a lot?
There are scenarios, like bulk updates, when it is established practice even in SQL world to switch off indices, import/update data and then rebuild the index. However, rebuilding index once a minute seems as something, what I would like not to do, if it would take too much time.

Dear Ivan,
Is it the correct behavior that indexes are automatically removed when I remove a document from a collection (version 6.3)? I mean text and
attribute
indexes, I haven't tried full-text index.
Yes, that was one more deliberate design decision to make updates as fast as possible in BaseX. The indexes are rebuilt whenever the "optimize" command is called; even so, tests with different systems have shown that our solution is often superior to implementations that refresh the index after each update operation. Still, one of our team members is currently integrating incremental index updates, which will be offered as an optional feature.
