My first Clerezza based application is running in production now
:-)
Hi Folks,
Just wanted to share some good news. Me an my team have our first Apache
Clerezza based application running in production. Unfortunately I can
not disclose any functional aspects of this application.
I would like to thank the Apache Clerezza community for the wonderfull
foundation that I/we could build upon.
There are still some aspects that need improvement, but I will get back
to that some other time
Thanks again.
Minto,

Even though it is a web application, it is not publicly accessible. So a
URL makes no sense.
However, I am still working on opening up a framework on which the
application was build. I also intend to including a sample application
as well. The framework was originally created for another application
which due to political reasons is still not yet in production.
I will definitely let you all know when I am ready to open it all up,
since I am very curious about your opinions ;-)
Regards,
Minto

Yeah, that would be exiting. Unfortunately it is not that kind of
application.
But if you come to work in the Netherlands and need a BSN (dutch social
security number), ..... ;-)
The one popping up most often is due to TDB
ConcurrentModificationException (CME) :-(
I already tried to minimize that by synchonizing access to the
Clerezza's TCManager. But still it pop's up occasionally. Last week we
experienced it about half a dozen times. During this period about 120
new graphs where created (approx. 25 triples per graph). But the strange
this that CME happens mostly during frequent querying a specific static
graph (50M+ triples).
To reduce the number of CME occurrences I will investigate if separating
that big static graph into a separate TDB instance makes sense. Still
this is only a short term fix, since it will most certainly popup again
when the other (none static) part grows both in the number of graphs
(currently 120 per week) and the number of queries on this data.
The other thing I could do is substitute TDB with another triplestore.
For this I still have Virtuoso on my Todo list.

Minto

That's great news, thanks for sharing!
Eager to unexpectedly get an org.apache.clerezza exception on a device I
might be using.... ;)
