It is possible to store any data in HBase which can be converted into byte[]. Yes using filters one can perform above kind of query. There is no built in filter for above kind of need but custom one can be created. But remember that there is no built in secondary indexing capability in HBase. Here by I can see you have a need for indexing a part of column value.

My concern is that I have been working with MongoDB, but now I am switching over to Hadoop and I want to use HBase for certain reasons. I was wondering if I can store Json files in Hbase in a way that I can query the Json files in Hbase as I can in Mongodb. Such as I can directly say Mongodb to get me all the objects having timestamp value of xxx date where timestamp is a field in Json objects stored in Mongodb. Can I perform similar operations on Hbase or does it have another approach for doing similar operations. I do not have much knowledge on Hbase yet. I am beginning to learn it, but I just want to be sure i am investing my time in the right direction. Thank you so much for the help, Regards, Panshul.
