HBase vs Cassandra: why we moved
Occasionally useful posts about RIAs, Web scale computing & miscellanea My team is currently working on a brand new product â€“ the forthcoming MMO www.FightMyMonster.com. This has given us the luxury of building against a NOSQL database, which means we can put the horrors of MySQL sharding and expensive scalability behind us. Recently a few people have been asking why we seem to have changed our pr

Decline of the Enterprise Data Warehosue Due to Hadoop, HBase, and Hive | Road to Failure
(â€¦due to Hadoop, HBase, and Hive) If you wanted to generate intelligence or other OLAPish things from large amounts of data (TBs) three years ago, you faced a terrifying prospect: You bought a server (or several large servers) costing $x00,000, paid for software from Oracle, Sybase, or IBM, and then prayed to Data Jesus that it would meet your needs for a few years. Youâ€™d find all the data you cou

"Until HBase came along, you basically had no random access in Hadoop clusters. This was a harsh limit on ad-hoc and selective queries. HBase rectifies that, however. Instead of following a paradigm of â€œIndex everything! Buy faster servers!â€, you can denormalize, replicate, and sort your data on

Hbase/ThriftApi - Hadoop Wiki
Thrift API This page discusses the Thrift client API for Hbase. Thrift is both cross-platform and more lightweight than REST for many operations. The latest version of the Hbase Thrift API is described by Hbase.thrift. Using the API Generating a Thrift client package Once Thrift is installed, use: thrift --gen [lang] [hbase-root]/src/main/resources/org/apache/hadoop/hbase/thrift/Hbase.thriftlang s

"HBase, MapReduce and the CLASSPATH MapReduce jobs deployed to a MapReduce cluster do not by default have access to the HBase configuration under $HBASE_CONF_DIR nor to HBase classes. You could add hbase-site.xml to $HADOOP_HOME/conf and add hbase-X.X.X.jar to the $HADOOP_HOME/lib and copy these cha

HBase - HADOOP2 - Apache Software Foundation
HBase: Bigtable-like structured storage for Hadoop HDFS HBase has an awesome community resource in our online book. It's maintained and looked after with diligence. In contrast, the below Wiki content has not been updated since 2012. For that reason, the Wiki has been deprecated (see HBASE-14481). Please update your links. You can find historical pages (which have been updated to give the new link

"Just as Google's [WWW] Bigtable leverages the distributed data storage provided by the [WWW] Google File System, HBase provides Bigtable-like capabilities on top of Hadoop Core. Data is organized into tables, rows and columns. An Iterator-like interface is available for scanning through a row range

Using Facebookâ€™s Thrift with Python and HBase - theatr.us - Yann's Musings
July 19, 2008 Using Facebookâ€™s Thrift with Python and HBase Today Iâ€™m going to show you how to interface Python to Apache HBase using Facebookâ€™s Thrift package. Hbase is a documented oriented database which is very similar to Googleâ€™s BigTable (in fact its more or less a clone of BigTable as seen in the BigTable paper). HBase has two primary interfaces - a REST API which is relatively slow, and a
