My data does not need to be loaded in realtime so I don’t have to use HBASE, but I was wondering if there are any performance benefits of using HBASE in MR Jobs, shouldn’t the joins be faster due to the indexed data?
Anybody have any benchmarks?
Generally speaking, hive/hdfs will be significantly faster than HBase. HBase sits on top of HDFS so it adds another layer. HBase would be faster if you are looking up individual records but you wouldn’t use an MR job for that.
