I am sorry, turns out the error is probably due to malformed input in one of the files which I will have to look into, not BaseX, would however still appreciate some indication regarding the rest of the questions.

All the best

Subject: A few general questions about BaseX

Hello everyone

I am trying to load BaseX with a large number of XML files (~500), each one a few hundreds of MBs big.

BaseX fails with a message along the lines “This is too big for one database”.

Can I please ask:

1) Are there any logs, beyond the DB logs? If yes, where can I find them?

a. The reason I am asking is because once basexgui gives the message, there is no indication about the error.
Ideally, I would like to know if this is a limitation on memory amount or number of items (?).

2) The parser options include reading XML files from archives, which is very convenient, but once the file has been
parsed, does BaseX require the “originals” for queries / returning results?

3) Is it possible to do federation with BaseX? In other words, let’s say I split a database in two large parts (as per #1),
is it possible to launch two baseX servers and then have them talk to each other so that ultimately I just query one of
them and get back unified results?

All the best
