It's faster to add documents, as this operation won't check if a
document already exists. In future versions of BaseX, however, we will
possibly merge these two functions.

Just one more hint, if we parallelly to the ongoing insertions post one
directly with basexclient, we don't experience this lag ...

This is the scenario on 2 DBs (same server) with the following sizes:

Hi, here is an example: A process that aggregates a few 100 topics and
transforms the aggregated content to a large HTML file for reviewers to see

- We sometimes need to query the content that has been transformed
after it has gone through some of the transformations.

Hi France,
I guess there is no simple answer to your question; it mostly depends
on the architecture of your approach what would be the best solution
and further steps. And I'm not quite sure what's the major challenge?

Hi,
I have an item that I would like to bring to attention. We have developed a
web controller to let users manages translation processes for BaseX
content. Our process is something like this:
- Users select content to translation (1 to 500 small files) + languages

It's not that trivial to optimize your query, but I'd like to let you
know that pre-evaluation of function literals works if function
declarations are swapped [1].
