I am planning to use cassandra and graph database in my spring web project. After googling i found some open source graph database. Actually i was looking for some open source graph database that has good support of cassandra and so i found titan graph database. It seems good but its new and don't know how much efficient it is for real world application that has huge data and read/write operations.
So i want to know that
1. Is there any more cassandra supported graph database?
2. Is titan good enough for real world web application with huge data and read/write operations?

I have a production web service built with Node JS(HTTP Server) on a Linux box with a HAProxy Load Balancer and wanted some kind of graphical tool to do live reporting on the server. I specially wanted to look at requests/min, request failures, etc. Anything out there people would suggest. I need something non-intrusive b/c I will be handling 20mil+ requests a day.
Have you looked at cube (https://github.com/square/cube), graphite/carbon (http://graphite.wikidot.com/) or opentsdb for such data monitoring/display?

Well of course we could use quartz.net, which comes with nice features like concurrency control and load balancing. However it seems a bit bloated to me.
1) Am I wrong about this ?
2) If not how would you implement a cloud compliant scheduler (ie: either deployed on premise or within azure) ? Is Lokad scheduling the best approach ?
Based on the answers to this question ( Recommend a C# Task Scheduling Library ) quartz.net running in a worker role instance is the way to go.

I am looking for a way to get some sort of monitoring, statistic or management data out of a node.js server instance - not sure what to search for or where to start. Any advice appreciated.
Stats would be requests processed (if applicable) - number of connections and so on.
Don't know if it will fit your needs, but you can try to look at node-monitor. Also Joyent is doing some advanced real-time performance analysis stuff, but it's probably only for their cloud services.
Nodetime can monitor different metrics, such as HTTP Response time, CPU time, OS Load, etc. It is also possible to set up email Alerts based on these metrics. More in the blog post Monitoring Node.js Application Performance.

When using linq to sql are there any benefits of using subsonic's active record as they are similar (table=class). Is this supported for Oracle or DB2?
Here's a couple comparisons/discussions:
http://subsonicproject.com/docs/Comparisons
Subsonic 3 LINQ vs LINQ to SQL
Linq to Sql vs Nhibernate vs SubSonic vs Stored Procedure (Help)
For your other question about database support, see:
http://subsonicproject.com/docs/Supported_Databases
Oracle support for SubSonic 3 is slated for SubSonic 3.1, which is currently a couple months away. See the discussion in the SubSonic Google groups for the latest development news:

Lately I have been reading a lot of blog topics about big sites(facebook, twitter, digg, reddit to name a few) using cassandra as their datastore instead of MysqL.
I would like to gather a list of resources to learn using cassandra. Hopefully some videos or podcasts explaining how to use cassandra.
My list
Twissandra - Twissandra is an example project, created to learn and demonstrate how to use Cassandra. Running the project will present a website that has similar functionality to Twitter
WTF is a supercolumn - WTF is a SuperColumn? An Intro to the Cassandra Data Model
I hope there are resources to watch howto use cassandra.
Many thanks,
Alfred
I found these articles really helpful coming from the relational world:
http://www.sodeso.nl/?p=80
http://www.sodeso.nl/?p=108
http://www.sodeso.nl/?p=207
Right now the docs available for cassandra is limited in some places. I've been watching the Cassandra user and dev email list like a hawk. That seems to be where most of the FAQ's live.
