Subject [jira] Commented: (CLEREZZA-286) Inserting lager literals takes too long
Date Wed, 25 Aug 2010 14:10:16 GMT


Reto Bachmann-Gmür commented on CLEREZZA-286:

If literals are externalized or not is an issue of configuration of the Clerezza instance
and is completely transparent to the application, it is not up to the app to decide if literals
are externalized or not. If you create an Mgraph <http://mygraph/>  (made the uri legal)
with the externalizer installed this will efectively also create the mgraph <http://mygraph/-externalizedliterals>
where instead of the literals you'll have references to them, but applications and users will
not access this MGraph (with the exceptions maybe of backup purposes).

> As binary resources are stored as literal values in the graph inserting literals of many
MB is not a seldom usage scenario. Inserting such literals however take very long and thus
require a very long write-lock on the graph (e.g. on my laptop 9 seconds when uploading a
40MB file with TDB and 3 second with Sesame)
