Reto Bachmann-Gmür commented on CLEREZZA-286:
---------------------------------------------
I committed a patch, it is not yet part of any launcher and I'm not yet closing
the issue as I think some more investigation on memory usage and performance
consequences are needed, speed could be (additionally) improved with:
- lazy writing of files: the file is written in the background, till it is
written the literal can be accessed from memory
- value-literals forwarding the value (like the byte array) to the store and
computing the lexical form only on demand
To test the patchdo the following:
- start clerezza
- install the bundle setting and set its startlevel to 3
- shutdown clerezza
- delete the mgraphs that shall use the externalizer (i.e. the content graph)
from the felix cache
- start clerezza again
if everything worked you will notice
http://tpf.localhost/content.graph-externalizedliterals alongside the normaal
contennt-graph
> Inserting lager literals takes too long

> 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)
