Incidentally, I'm still in the process of working on the JCR benchmark. I have a set of elements stored, in a set of documents (text), a set of audio files (streams), and a large number of, well, numbers. Still some synchronization problems, as I'm having to work out how locks work in JCR (hey, I just started writing the thing today, and I think I know where the issue is.)
Writing is only the first step, of course. Reading, querying are next. Initial results on stores, though, show the filesystem as being *slightly* faster than the RDMS, with BDB integration still on its way. Stores are likely to be far more rare than reads and queries, so this data isn't worth a lot yet. Alexandru and I will probably have a project set up on googlecode or java.net soon so everyone can participate. -----Original Message----- From: Nicolas [mailto:[EMAIL PROTECTED] Sent: Friday, October 27, 2006 5:57 PM To: [email protected] Subject: Re: PersistenceManagers Benchmark Hi Marcin, I think they were discussing about the importXML method (available in Workspace and Session classes). If my understanding of Jackrabbit is correct, those methods allow specifically to import some XML in a workspace; Nico On 10/27/06, Marcin Nowak <[EMAIL PROTECTED]> wrote: > > As far as I know atomic parsing of nodes from XML is not available a > this moment in JackRabit, am I right? > > BR, > Marcin Nowak > > -----Original Message----- > From: robert burrell donkin [mailto:[EMAIL PROTECTED] > Sent: Friday, October 27, 2006 1:41 PM > To: [email protected] > Subject: Re: PersistenceManagers Benchmark > > On 10/27/06, Marcin Nowak <[EMAIL PROTECTED]> wrote: > > Hi, > > > > Regarding stress tests, I need to know where are the limitations of > > importing XML's and where is a huge memory usage coming from. > > transactional importing of xml data is always going to be memory > intensive > > the memory used in binding could be reduced by (say) custom SAX > handling or pull parsing the input stream so long as each node were > saved atomically > > - robert > > > -- > Empowering business > http://webinars.comarch.com > -- a+ Nico my blog! http://www.deviant-abstraction.net !!
