Slices in BDB

Slices in Berkeley DB (courtesy of Charles Koester)  With the new Berkeley DB 6.2 release, there are a number of new features.  One of the more exciting ones is the use of Slices. It is possible to improve the multiprocessor scaling of your DB databases by implementing slices. Slices cause your database records to be spread evenly across sub-environments and sub-databases using an internal hashing algorithm. Because your records are stored in separate physical environments and...

Data management in unexpected places

Data management in unexpected places When you think of network switches, routers, firewall appliances, etc., it may not be obvious that at the heart of these kinds of solutions is an engine that can manage huge amounts of data at very high throughput with low latencies and high availability. Consider a network router that is processing tens (orhundreds) of thousands of network packets per second. So what really happens inside a router? Packets are streaming in at the rate of...

Yammer, Berkeley DB, and the 3rd Platform

If you read the news, you know that the latest high-profile social media acquisition was just confirmed. Microsoft has agreed to acquire Yammer for 1.2 billion. Personally, I believe that Yammer’s amazing success can be mainly attributed to their wise decision to use Berkeley DB Java Edition as their backend data store. :-) I’m only kidding, of course. However, as Ryan Kennedy points out in the video I recently blogged about, BDB JE did provide the right featureset that...

A few weeks back, Ryan Kennedy of Yammer gave a talk about Berkeley DB Java Edition. You can find it posted here on Alex Popescu's Blog, or go directly to the video post itself. It was full of useful nuggets of information, such as why they chose to use BDB JE, performance, and some tips & tricks at the end. At over 40 minutes, the video is quite long. Ryan is an entertaining speaker, so I suggest you watch all of it. But if you only have time for the highlights, here are...

Now you can build Berkeley DB into your Android apps

I want to make everyone aware of a small change we made in the last release that promises to make a big difference for our customers using Android. We added support for the Android platform some time back. However, there was a caveat: Berkeley DB had to be integrated at the OS level, replacing the SQLite routines that usually ship with Android. Having Berkeley DB built into the OS provided some advantages. But it also meant that customerswere unable to build a BDB-enabled app...

Is Berkeley DB a NoSQL solution?

Berkeley DB is a library. To use it to store data you must link the library into your application. You can use most programming languages to access the API, the calls across these APIs generally mimic the Berkeley DB C-API which makes perfect sense because Berkeley DB is written in C. The inspiration for Berkeley DB was the DBM library, a part of the earliest versions of UNIX written by AT&T's Ken Thompson in 1979. DBM was a simple key/value hashtable-based storage library....

Now in this final installment we'll see Berkeley DB at work storing object instance data referenced by STL structures. Berkeley DB's C++ STL API, the dbstl, will automatically store the STL container in an on-disk database, but what about the data referenced by the elements within the STL container? You must choose how to store the values pointed to...

Berkeley DB Java Edition 4.1.6

Yesterday we released a new version of Berkeley DB Java Edition. This new release has some major enhancements for speed. BDB JE has always been as fast as the I/O + stable storage (disk) system for writes due to its write-once, append-only log-based architecture for fully durable commits (semi-durable, those which commit to operating system buffers rather than to the stable storage, operate at in-memory speeds). The issue until now was with random reads. Now, even with modest...

The first release of Oracle Berkeley DB with support for SQL came out roughly six months ago and was on par or better in terms of performance with SQLite while keeping 100% drop-in API compatible with the SQLite3 APIs. We tested it in Firefox, Chrome and other popular and demanding SQLite-based open source applications to make sure it worked out of the box and it did! The advantages of BDB's storage engine were clear to everyone who tried it for themselves; BDB is faster,...
