Subject Querying
Date Thu, 11 Sep 2008 04:39:46 GMT
Hello all,

I have a question regarding querying data that is in HBase. Is there a
way to fairly efficiently query, e.g. all rows where the row key is a
certain value? Does HBase API provide some sort of query interface
besides a Scanner to just get all the rows that have a certain column
family:column_qualifier? What would you say are the limits of the
existing HBase query API? Can a Hadoop map/reduce job take hbase data
as input and process/query it in an efficient manner? Sorry if these
questions don't make sense -- just started learning HBase this
