Bart Firstly TDB is entirely thread safe as it implements serialisable transactions with a Multiple Reader + Single Writer concurrency model
Secondly it should be possible to configure Fuseki with a TDB dataset that is attached to a Text Index such that the text index is automatically updated. See https://github.com/apache/jena/blob/master/jena-fuseki/config-tdb-text.ttl for an example assembler file that does just this. Of course if you do updates by taking your Fuseki instance offline and then using tdbupdate (or an application that updates the TDB dataset) then the index would not automatically updated and would need to be rebuilt separately. A re-index would require read access to the TDB dataset and write access to the Lucene index so I would guess it could be run while Fuseki is online though I'm not sure anyone has necessarily ever tried that. More details of your workflow would be useful Thanks, Rob On 18/11/2014 16:21, "Bart van Leeuwen" <[email protected]> wrote: >Hi, > >I've played around with Fuseki 1.1.1 >I created a TDB store which I filled with data through the Fuseki control >panel > >I followed the instruction for full text queries at: >http://jena.apache.org/documentation/query/text-query.html > >Everything is up and running and works like expected. > >Now the data in the TDB store will be updated now and then is it possible >to run the index updater while fuseki is still up and running ? >or do I need to bring fuseki down during that process ?
