Database Limits
by Dave Glick 05 Jul '11

05 Jul '11

At one point in the past there were limits to how many unique element names could be stored/indexed in the database. We exceeded that limit for our documents and so to address the problem we started splitting out our data into multiple databases and using some hacky rewrites of the QueryContext class to work with them as if they were in one database. We haven't synced up in a while and the BaseX API and class structure has undergone some really good improvement in the meantime. I'm in the processing of revising how we interface with and use BaseX and would like to consider going back to a single database if possible. In general, the question is: does a limit to the number of unique element/attribute names still exist? If so, what is it? Time permitting (it appears you guys have been busy pushing out great new features recently) I think a Wiki page with a list of all limits on the database would be very helpful (I.e., limited to X number of elements, limited to Y number of attributes per element, limited to Z size on disk, etc.) Thanks! -- Dave Glick | dglick(a)dracorp.com<mailto:dglick@dracorp.com> | 703-299-0700 x212 Data Research and Analysis Corp. | www.dracorp.com<http://www.dracorp.com>

bulk-load
by Tomaso Musitelli 04 Jul '11

04 Jul '11

Hello dear BaseX Team, I would like to load a big number of small documents in Basex. What I do is to use a little Java program: Context ctx = new Context(); new CreateDB("basex1").execute(ctx); new CreateIndex("fulltext").execute(ctx); System.err.println("\n* Show database information:"); System.err.print(new InfoDB().execute(ctx)); for( ... ) { new Add(somedata, miname, collection).execute(ctx); } I dont know if it is correct , efficient ? Do you have a notion of transaction, like begin/commit ? ( I did not see something like that) My concern is that it seems not to behave well when the number of documents goes big: (each doc is about 2500 bytes) 10000 => 54 seconds ; 5.4 millis / document 20000 => 202 s ; 10 ms 50000 => 862 s ; 17.2 ms And in fact I want to store more than 1 million! Actually is there a limit in size ? Is 1 million x 2.5Kb OK? Thank you very much Tomaso

API does not contain XQueryService interface
by Robby Pelssers 04 Jul '11

04 Jul '11

Hi all, I was trying to test some code I wrote for Sedna XML DB but I noticed that org.xmldb.api.modules.XQueryService is not part of the API. I checked EXIST and Sedna and both include this Service. Is there any particular reason why this not included by BaseX? Kind regards, Robby Pelssers
