I'm wondering what sorts of data access patterns (if any) people are using on top of HBase?
For example, is a DAO pattern applicable? Seemed reasonable at first, but based on limited experience, I see a couple of mismatches: 1) Generally, if the DAO was backed by an RDBMS, all the columns are stored together, so it's no problem to read them all in and create a light Data Transfer Object. In Hbase, however, it probably only makes sense to read in complete column families rather than the complete "row". On the other hand, there are some lazy variations that might be appropriate? 2) Also, again based on my limited hbase experience, it seems more common to want to operate on ranges of data (either a scan or an update), rather than individual entities. I suppose I could make a DAO pattern work, but I'm really looking for some feedback on people's real world experiences... has this pattern proved useful for people? Are there other patterns that are more applicable? Marc
