如果我使用prefixfilter进行查询,我不知道为什么它会很慢.有人可以解释一下查询HBase的最佳方法,谢谢.

hbase(main):002:0> scan 'userlib',{FILTER=>org.apache.hadoop.hbase.filter.PrefixFilter.new(org.apache.hadoop.hbase.util.Bytes.toBytes('0000115831F8'))}
ROW               COLUMN+CELL                                                                                                                                
0000115831F8001   column=track:aid, timestamp=1339121507633, value=aaa
