Hi all,
I am trying to design the row key for a table. Our application would
perform many queries on columns. My question is that is that a good way to
put all values from columns into the row key? Thus I can use filters like
FuzzyRowFilter to get rows and parse the values directly from row keys.

Hi All,
HBase has sorted and indexed Hfile format, which enables fast lookup.
I am wondering is there any other feature help Hbase achieve efficient
random access?
I want to know the whole story, but I can't find any article talks about
random access in HBase in high level.
Can anyone help me res

Hi All,
I've read many articles, including Bertozzi's Who needs a Master, but I am
still confused about the Hmaster.
If the Hmaster goes down, does the system need to take any failover ?
Or just elect a new master, and the new one can restore all the information
from hbase:meta?
Best regards,
Ya
