Performance Degraded In function-lookup
by Carl Leitner 24 Feb '14

24 Feb '14

Hi, I noticed a significant performance degradation in the function-lookup method introduced at: https://github.com/BaseXdb/basex/commit/4aeb4bdc74d980b4c8f2e27546d21fdc1eb… Where as at: b8b3dd2bee205303aeab3e8a0967b371a2ad7ef7 I have: > xquery import module namespace csd_bsq = "https://github.com/his-interop/openinfoman/csd_bsq" at "/Users/litlfred/pulsar_cats/openinfoman/repo/csd_base_stored_queries.xqm"; let $r:= function-lookup(xs:QName('csd_bsq:facility_search'),2) return () Query executed in 22.57 ms. At 4aeb4bdc74d980b4c8f2e27546d21fdc1ebaeb77 I have: >xquery import module namespace csd_bsq = "https://github.com/his-interop/openinfoman/csd_bsq" at "/Users/litlfred/pulsar_cats/openinfoman/repo/csd_base_stored_queries.xqm"; () Query executed in 17.48 ms. >xquery import module namespace csd_bsq = "https://github.com/his-interop/openinfoman/csd_bsq" at "/Users/litlfred/pulsar_cats/openinfoman/repo/csd_base_stored_queries.xqm"; let $r:= xs:QName('csd_bsq:facility_search') return () Query executed in 20.44 ms. >xquery import module namespace csd_bsq = "https://github.com/his-interop/openinfoman/csd_bsq" at "/Users/litlfred/pulsar_cats/openinfoman/repo/csd_base_stored_queries.xqm"; let $r:= function-lookup(xs:QName('csd_bsq:facility_search'),2) return () Query executed in 716.18 ms. Any suggestions on how to avoid this? Thanks so much. Cheers, -carl

Query plan via REST interface?
by Christian Lang 21 Feb '14

21 Feb '14

Hi, is it possible to obtain the query plan via the BaseX REST interface? I tried: curl -i -X POST -H "Content-Type: application/xml" -d "<query xmlns=' http://basex.org/rest'><text>some_query_here</text><option name='xmlplan' value='true'/></query>" "http://xyz" but this only returns the query results, not the plan. Thanks, Christian

Using Client/Server? How-to
by Pratik Kharwade 21 Feb '14

21 Feb '14

Hi, I am using BaseX to store certains documents. Till now as the DB was small, I alone was able to handle it ie.; check, modify etc etc. operations. Now the documents are in tons and I have kept 2 guys to work on the same, with proper training, I need to have a client-server setup. I have gone through the Database Server wiki. Being new to this kind of environment, I have few questions, might be quite basic, but strange to me :) As far as I know and have understood what I will have to do is - 1. I will have to keep the DB on a server with proper networking so that the clients can access the DB. 2. I will have to change the DB path on clients (in Preferences) and it would be the Server's path. 3. Instead of running the stand-alone, I will have to start Server and on clients, the BaseX Client. So far, I haven't tried this, as any mistake on my part or of employees' might damage the DB. I need a proper guidance to start with it. Regs Pratik

fn:doc-available()
by Hans-Juergen Rennau 19 Feb '14

19 Feb '14

Dear BaseX team, I am puzzled by the behaviour of fn:doc-available when applied to a zip file: doc-available('/user/xsd/niem-2.1.zip') yields this error: [BXDB0006] Database path '/user/xsd/niem-2.1.zip' yields no documents. Kind regards, Hans-Juergen

function parse-xml() very slow in embedded mode
by Johan Mörén 19 Feb '14

19 Feb '14

Hi I'm using BaseX in embedded mode (no database) and need to transform an xml payload that contains elements containing string-encoded xml in this form ... <str><objectInstance fetchDate="2014-02-14T13:00:53.374+01:00"> <createdDateTime>2012-12-04T08:55:26.195Z</createdDateTime> </objectInstance></str> ... I have both tried using xquery update (copy, modify) and with a simple identity-transform function that intercepts the <str/> element and replaces it with the results of parse-xml(.) When executing the query in BasexGUI both solutions performs very well. However if i invoke it via the QueryProcessor in my java-process it is 50 to 100 times slower. Any clues to what i might be missing? Regards, Johan Mörén

Updating Functions and Custom Types
by Stefan Sechelmann 19 Feb '14

19 Feb '14

Hello BaseX Team, we are currently using BaseX with great success in a WebApp/Database environment. Firstly I want to thank you for the great work on version 7.8, we like the new new features very much. Here are two feature requests that we would love to see being included in the future: - We have a test suite that invokes various updating functions using the standalone client. On the other hand non-updating functions are tested by a query test suite using the unit module. It would be great to include the tests for updating functions into the xquery test suite thus removing the condition that a test function must not be updating. - Inside our restxq backend we have a lot of functions that pass complex data structures to other functions or receive them via http. In order for these functions to be correctly typed we would need custom type support via XML-schema includes. This would greatly improve the quality of our code. Greetings and best regards Stefan -- Stefan Sechelmann DFG-Forschungszentrum Matheon Mathematik für Schlüsseltechnologien Technische Universität Berlin Sekretariat MA 8-3 Tel. 030/314 29 486 Straße des 17. Juni 136 Fax 030/314 79 282 10623 Berlin sechel(a)math.tu-berlin.de http://www.math.tu-berlin.de/~sechel

Dear subscribers, it was great to meet some of you live in Prague! And once again I would like to thank all our speakers (Lars Johnsen, Gerrit Imsieke, Yoann Maingon, Jean-Marc Mercier and Michael Sperberg-McQueen) for making the user meeting to a memorable event! Have fun with BaseX 7.8, and we are looking to your feedback, Christian PS: Maybe we'll see each other in London or Amsterdam, or at the Balisage? We'll tell you in time if we will be participating as well.
