2nd Munich OpenHUG | HBase Explorer
https://hbaseexplorer.wordpress.com/2010/02/26/2nd-munich-openhug
February 26, 2010. Christoph Rupp started with a introduction to his embeddable HamsterDB. A nice and light alternative for BerkeleyDB. Beside a comprehensive feature set, he impressed with strong quality rules that are applied to each release. A embedded fast DB is certainly a different world than the massive scaling we do with Hadoop and Co, but why not imagine the HBase Shards using a really fast embedded piece of C-Code? This was our second. March 2, 2010 at 12:18 pm. Leave a Reply Cancel reply.

Where to put my persistence layer? January 19, 2010. After you play a while with the put()’s and get()’s of your Hbase client, you’ll probably start to think about how to organize the mess. When a classic DAO…. This classic approach with one backend database ensures that the client code needs no knowledge of the database and also not of the actual persistance strategies in the Persistance Layer (which was called. The Database itself ensures the data consistency and has a strong API (SQL). We would have t...

Getting tomcat 7 to fly! | 99apz
https://99apz.wordpress.com/2012/05/01/getting-tomcat-7-to-fly
Getting tomcat 7 to fly! Getting tomcat 7 to fly! Mai 1, 2012. This is the story of one that went to make his java webapp running fast and stable on the latest greatest software. After running the system for a while, a new operating system was released, the tomcat web server had a series of important upgrades, and finally the java platform switched to „7“. So a lot of things, all by itself promising more performance and more stability. Java 7, I use the oracle variant. Occationally its useful to fire up ...

Quickly gather an overview about a software project. Februar 19, 2012. Whats in that Project? It occationally happens that you want to get an overview of the files within a (new) project. This includes the number of files, the lines of code (LOC), the file types (and thus programming languages) etc. I use this groovy script. To get that quickly. Here is a sample output for a fresh checkout of hadoop-hbase:. Prompt groovy scan.groovy /projects/hbase trunk. V grep ".py". Changing the way RRD collects data.

Count the cycles! | 99apz
https://99apz.wordpress.com/2012/08/06/count-the-cycles
August 6, 2012. As we program more and more multi-threaded, measuring the execution time of a single function does often not give as a clear idea about the impact on the overall system. I want to illustrate that a bit here. Say you have some code that executes in 10ms, the time needed to run all single code cycles on one CPU. Now you add some lines, it runs 11ms. Is it now 10% slower? I’d say at least, but it can get worse. Its all linear, one can express this problem as. Of course, modern Threadpool.

IntelliJ and Encoding Mess with i18n properties. IntelliJ and Encoding Mess with i18n properties. Juni 24, 2012. I recently run into a weird encoding problem with properties files in java’s i18n localization. I am a IntelliJ. Freak – but here my IDE drove me a bit crazy. It seems I hav’nt RTFM. While IntelliJ has very nice automatics for translating the special chars into plain ascii „ uFFFF“ representations, it needs a careful setup for this to work. Remember, if you use Java’s RessourceBundles. This im...

März 23, 2012. Damn, Now I added 1000% more hardware, but I get back only 200% more overall throuput! Lets assume we have a web service. Each call will do something immediately useful for the caller (lets call it paywork, green. But it also brings us a bit of homework – things that need to be done sooner or later to complete our service ( blue. That can be a simple thing like logging to a file, but it may also be an asynchronous job that you pushed into your message queue. If your are not lucky, you̵...

September 22, 2012. MySQL’s binary replication is a great thing, but as with many things that run seamlessly for long, you tend to forget how it works and what to do if something actually goes wrong. This is my note to remember it as it happens to my servers once in two years…a time I seem to have forgotten most of it. After you’ve repaired A, it gets a bit tricky: How to get the server A now in sync to make it a useful hot-standby? For that to work, binlog must have bin enabled also on the slave (B), bu...

Allgemein Parsing Numbers for the World. Parsing Numbers for the World. April 1, 2012. Have you ever been fighting with parsing numbers, provided by humans? Weird Imagine the folks living near the border of germany to switzerland: If they type 1.2 they actually mean 1,2 (for us germans)! And they type 1’200 if they mean 1200? You from US might type 1,200 instead. Really tricky – unless you know the locale of the human. But often they (or their web browser) dont. So with your Online-Shop. DoubleValue = do...

The Base at the Beginning of the Hypergrid. Friday, September 6, 2013. Alpha "Rift enabled" viewer and a new Rift demo region on osgrid. Tempus fugit. a lot has happened since my last post:. I finally got my very own Rift dev kit. Although it is always mentioned that this is in no way the final consumer product. It is miles ahead of what i was able to tinker using my 7" tablet, some lenses and cardboard. You put it on your head, fire up a demo and "baam" you teleport into that new world. So far my goal i...

有态度的HBase
Skip to main content. 和读相比，HBase写数据流程倒是显得很简单 数据先顺序写入HLog，再写入对应的缓存Memstore，当Memstore中数据大小达到一定阈值 128M 之后，系统会异步将Memstore中数据flush到HDFS形成小文件。 Full GC问题之前在一些文章里面已经讲过它的来龙去脉，主要的解决方案目前主要有两方面需要注意，一方面需要查看GC日志确认是哪种Full GC，根据Full GC类型对JVM参数进行调优，另一方面需要确认是否开启了BucketCache的offheap模式，建议使用LRUBlockCache的童鞋尽快转移到BucketCache来。 2 资源调度，主要针对任务进行优先级调度，通常会优先调度实时交互而且小的任务，而批量操作任务或者长时间操作任务 大scan 优先级相对较低，详见HBase-1099. 正所谓 恐惧来源于未知 ，不知所措意味着我们对RIT知之甚少，然而 凡事都有因果，万事皆有源头 ，处于RIT状态的Region只是肉眼看到的一个结果，为什么会处于RIT状态才是问题探索的根本，也是解决问题的关键。
