Re: Is it good choice to access hbase via DAO?

Yes, any database operation. You can have multiple Dao classes with different purposes. Regards, Nestor On Wednesday, July 20, 2016, Yu Wei wrote: > Could it also support batch processing? > > > > From: N?stor Bosc?n

Re: Is it good choice to access hbase via DAO?

The idea of the DAO class is to encapsulate your data interactions in one class so that all HBase specific classes go on that DAO class. To me it makes perfect sense. The advantage is that in the future if you want to change Hbase for something else you will probable only change that DAO class.
