but yes you will not be having different versions of those objects as they are not stored as such in a table. So, that's the down side. In case your objects are write once read multi types, I think it should work. Let's see what others say :) ~Himanshu On Tue, Sep 7, 2010 at 12:49 AM, Himanshu

I'm not sure what you mean by optimized cell size or whether you're just asking about practical limits? HBase is generally used with cells in the range of tens of bytes to hundreds of kilobytes. However, I have used it with cells that are several megabytes, up to about 50MB. Up at that

Hi JG, Thanks for your reply. As far as I have read in Hbase's documentation and wiki, the cell size is not supposed to be larger than 10 MB. For the row, I am not quite sure, but it looks like 256 MB is the upper limit. I am considering store some binary data used to be stored in RDBM blob field.
