Hello,
We are now choosing a xml database and BaseX is one of the candidates. I want to know if BaseX can support distributed storage and distributed query. If it can support these features, pls give me some advices or documents.
Thanks

Hello,
If distributed storage implemented via NFS (Network file system), the answer should be yes. For example, folder /opt/strage/data1/. maps to server1, another folder /opt/storage/data2/. maps to server2, "distributed" query might look like this:
let $A := fn:doc("/opt/storage/data1/data.xml")
let $B := fn:doc("/opt/storage/data2/data.xml")return $A//some-node + $B//some-node

Hello Chen,
at the moment, the answer to this question is still no. We are working into this direction, but we are not production ready.
As Sergey outlines you can of course use a distributed file system as basis for BaseX.
Cheers,
Dirk
