    <p>Our analytic server is written in c++. It basically queries underlying storage engine and returns a fairly big structured data via thrift. A typical requests will take about 0.05 to 0.6 seconds to finish depends on the request size.</p> <p>I noticed that there are a few options in terms of which Thrift server we can use in the c++ code, specifically TNonblockingServer, TThreadedServer, and TThreadPoolServer. It seems like TNonblockingServer is the way to go since it can support much more concurrent requests and still using a thread pool behind the scene to crunch through the tasks. It also avoids the cost of constructing/destructing the threads.</p> <p>Facebook's update on thrift: <a href="http://www.facebook.com/note.php?note_id=16787213919" rel="nofollow noreferrer">http://www.facebook.com/note.php?note_id=16787213919</a></p> <blockquote> <p>Here at Facebook, we're working on a fully asynchronous client and server for C++. This server uses event-driven I/O like the current TNonblockingServer, but its interface to the application code is all based on asynchronous callbacks. This will allow us to write servers that can service thousands of simultaneous requests (each of which requires making calls to other Thrift or Memcache servers) with only a few threads.</p> </blockquote> <p>Related posts on stackover: <a href="https://stackoverflow.com/questions/954945/large-number-of-simulteneous-connections-in-thrift">Large number of simulteneous connections in thrift</a></p> <blockquote> <p>That being said, you won't necessarily be able to actually do work faster (handlers still execute in a thread pool), but more clients will be able to connect to you at once.</p> </blockquote> <p>Just wondering are there any other factors I'm missing here? How shall I decide which one fits my needs the best?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
