James, you are right, OPTIMIZE ALL solves the problem. The txt.basex was growing at each replace, other files staying almost identical. Thanks a lot !

Re: [basex-talk] size on collection in the time

Hi Dirk, attached a simple test-case to reproduce the problem. data.xml is a file that contains attributes and text. Each time you run run.sh, data.xml is re-created, with current-dateTime() in. So each time, the file content is changed. The file size does not change (date format ensures it). reload.bxs deletes the file from the collection and add it back to the collection. run.sh displays the size of files in the collection. Each time you start run.sh, file size grows. You need to modify run.sh to set the correct directories locations. You have to add saxon9he.jar to run it. I hope this will help, Christophe Le 03/09/2015 15:27, basex-talk-request(a)mailman.uni-konstanz.de a écrit : > Send BaseX-Talk mailing list submissions to > basex-talk(a)mailman.uni-konstanz.de > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.uni-konstanz.de/mailman/listinfo/basex-talk > or, via email, send a message with subject or body 'help' to > basex-talk-request(a)mailman.uni-konstanz.de > > You can reach the person managing the list at > basex-talk-owner(a)mailman.uni-konstanz.de > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of BaseX-Talk digest..." > > > Today's Topics: > > 1.

Marc, Are you using the updatable index? UPDINDEX true. If so, if you look back through the list Christian and I had an exchange on this as I was experiencing an ever growing index - a replace always appended to the end of the index. IIRC the logic is a bit better now in that if on a replace there is enough room in the index structure to reuse slots it will, but if not it will be appended. And the db will reuse empty slots while the database remains open. I can’t remember which is the first version where this change was made, sorry. I had a DB the other day that had got to 14GB but was only around 600MB once I did a full optimise. My suggestion is next time to try a full optimise instead of dropping the collection and see if that helps.

Basex 8.2.3 data not shown, until OS restart
by Mansi Sheth 02 Sep '15

02 Sep '15

Hello, This is something very weird. I import bunch of XML files, into this latest version of based using Java API. When trying to access this data (via basex command line client or REST), doesn't show any databases at all. These databases shows up only after restarting OS. Is this a known issues ? or just me ? - Mansi

Finding document based on filename
by Mansi Sheth 01 Sep '15

01 Sep '15

Hello, I would be having 100s of databases, with each database having 100 XML documents. I want to devise an algorithm, where given a part of XML file name, i want to know which database(s) contains it, or null if document is not currently present in any database. Based on that, add current document into the database. This is to always maintain latest version of a document in DB, and remove the older version, while adding newer version. So far, only way I could come up with is: for $db in all-databases: open $db $fileNames = list $db for eachFileName in $fileNames: if $eachFileName.contains(sub-xml filename): add to ret-list-db return ret-list-db Above algorithm, seems highly inefficient, Is there any indexing, which can be done ? Do you suggest, for each document insert, I should maintain a separate XML document, which lists each file inserted etc. Once, i get hold of above list of db, I would be eventually deleting that file and inserting a latest version of that file(which would have same sub-xml file name). So, constant updating of this external document also seems painful (Map be ?). Also, would it be faster, using XQUERY script files, thru java code, or using Java API for such operations ? How do you all deal with such operations ? - Mansi
