Use of Jackrabbit in commercial product and scalability numbers for
Jackrabbit w/w/o RMI
Hi ,
I would like to know if anyone is using Jackrabbit in live
commercial/OS project/product .
Also , does anyone have any scalability numbers for Jackrabbit,
preferably with RMI.
Appreciate your reply.
Thanks,
Ruchi

That's very true.
You can do the same over http with just some input/output stream bridging.
Have tried it, and it's quite performing, and also you can move massive
chunks of data with a very small heap.

That's a good point. The RMI layer is actually pretty efficient from a
bandwidth perspective, i.e it supports efficient streaming of binary
values.

It works ok for the load it has to cope with, but I cannot say that the
server is stressed by the number of operations [it basically serves
large files (videos)] and the site does not have the load of youtube...
I cannot tell you the numbers however (NDA).
In the tests I have done, bandwidth is the limiting factor and I did not
try to stress jackrabbit on its own, but it never was the limiting factor.

Hi Dominique,
How does it perform on RMI ? Do you have any statistics for this ?
Thanks,

The content repository of the player at www.freecaster.com is using
jackrabbit. It is deployed as an RMI server providing data to a
webobjects application.

We're embedding it into a desktop app as the datastore for a single-
user local desktop product. If this works out well, we'll try adding
a network layer to open it up for workgroup collaboration.
So far the big benefit for us has been developer time savings.
Jackrabbit does so much for you in regards to dependancy tracking and
versioning and XPath searching; we would never have been able to
implement a decent solution in the amount of time that we have.
Our datastores aren't huge, however, so I can't attest to the
scalability.

Model 1 (embedded), due to various reasons including the way I have
structured the application.

Alex, which deployment model do you use?

We unfortunately don't have very organized scalability/performance
test suites in place to give very specific numbers, but I've seen
successful load tests that go up to tens of millions of nodes and
terabytes of content per workspace.
Jackrabbit also performs quite well on concurrent read access thanks
to the aggressive read caching that takes place at the item state
manager level.
However, under the item state managers all persistent content accesses
are currently serialized (see JCR-314), which causes a bottleneck for
heavily concurrent write loads and read loads with widely distributed
access patterns.

I guess there are already quite a few people doing so. See the JCR
Links page on the Jackrabbit wiki for some commercial applications
based on Jackrabbit.

What sort of scalability are you interested in? Number of nodes, total
amount of content,
number of (concurrent) users, perfromance under load, ...
Note that the current RMI layer is heavily constrained by network
latency as it normally uses a large number of small requests. For best
performance you should typically use a local Jackrabbit instance.
