Not that I know of, and I am going to be the annoying person who tells you to rethink that "dedicated forest" approach.
The design of MarkLogic is to place documents into forests automatically. This creates balanced, fairly homogenous forests. If you try to manage document forest assignment manually, you will probably create unbalanced, heterogeneous forests. You may find yourself fighting with the software in other places, too. Sometimes developers new to MarkLogic think that it would be a good idea to put documents of type A in forest A, and type B in forest B: to dedicate forests by content. Even http://docs.marklogic.com/guide/ingestion/xquery mentions some "advantages" to this approach. But I think it is misguided, and nearly always a mistake. Before embarking down that path, you should understand the potential disadvantages of that approach. Consider what happens when you query heterogeneous forests. If you have a lot of queries on documents of type A, forest B is relatively idle. Because forests operate in parallel, this is a net loss vs concurrency across multiple forests. So this approach throws away much of the advantage of multiple CPU cores, and multiple disk subsystems too. This approach also makes query development more awkward, because querying by forest is not as straightforward as querying by collection or directory. IN my opinion the use-cases mentioned at http://docs.marklogic.com/guide/ingestion/xquery are better addressed using other product features. If you only want to back up the latest updates, use journal archiving. If you want to mix fast storage and slow storage, set up the faster storage as a fast data directory. So I prefer to let the system place documents wherever it likes, and use directories or collections to manage them. When each database forest contains documents of different types, every query will parallelize across the database forests. -- Mike On 28 Jul 2013, at 22:46 , sini narayanan <[email protected]> wrote: > Hi All, > > Using MarkLogic content pump, is there any option to load documents into > dedicated forest of a database? > > Thanks, > Sini > _______________________________________________ > General mailing list > [email protected] > http://developer.marklogic.com/mailman/listinfo/general _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general
