Hi Erol,

it's true that one database and one single XQuery call won't be enough to process data of that size. As BaseX does not natively support distributed storage and parallel queries, I would suggest the classical (manual) way: split the data to multiple databases, run the query on each instance and eventually merge the textual results. This could be done in a few lines of code, provided that the queries are not sophisticated, the database contents are disjunct, no concurrency issues have to be considered, etc.

Hope this helps, Christian

Hi Christian,

I appreciate a new release of BaseX.

I have one question on storing a huge data,say 10-50 petabytes data, with Basex. I expect current version may not handle it properly. Can we distribute XML data across clusters of nodes and have a parallel xquery to be run across nodes and get result? I would like to know how it can be implemented such a big clustered xml database and have efficient xquery on this cluster.

Regards

Dear all,

we are excited to finally announce the release of BaseX 6.0! It offers a bunch of new features, such as:

• a full implementation of XQuery Update, reaching 100% in the W3C Test

Suite.

• an enhanced client/server architecture with ACID-safe transactions,

user and password management and transaction logging.

• extended XQuery Full Text features, supporting TF/IDF scoring, stop

word lists, fuzzy querying, etc.

• the improved creation of index structures, using constant memory.
• optimizations to increase the use of index structures and iterative

query processing.

As usual, please find more information at http://basex.org/

All the best,
