Nobody from the HBase project was consulted on the results or to do such tuning, as is common courtesy when running a competitive benchmark, if the goal is a fair test. Furthermore the "benchmark" code was not a community accepted benchmark such as YCSB. I do not think the results are valid beyond being some vendor FUD and do not warrant much comment beyond this. Best regards, - Andy Problems worthy of attack prove their worth by hitting back. - Piet Hein (via Tom White) --- On Wed, 5/25/11, edward choi wrote: > From: edward choi > Subject: hbase and hypertable comparison > To: user@hbase.apache.org, common-user@hadoop.apache.org > Date: Wednesday, May 25, 2011, 12:47 AM > I'm planning to use a NoSQL > distributed database. > I did some searching and came across a lot of database > systems such as > MongoDB, CouchDB, Hbase, Cassandra, Hypertable, etc. > > Since what I'll be doing is frequently reading a varying > amount of data, and > less frequently writing a massive amount of data, > I thought Hbase, or Hypertable is the way to go. > > I did some internet and found some performance comparison > between HBase and > HyperTable. > Obviously HT dominated Hbase in every aspect (random > read/write and a couple > of more) > > But the comparison was made with Hbase 0.20.4, and Hbase > had much > improvements since the current version is 0.90.3. > > I am curious if the performance gap is still large between > Hbase and HT. > I am running Hadoop already so I wanted to go with Hbase > but the performance > gap was so big that it made me reconsider. > > Any opinions please? >
