Hi, On the opentsdb website [1] you can read the following: --- The problem with HBase's implementation is that every single cell also stores the row key and a bunch of other redundant information. In the example above with 2 rows and 16 cells, the 13-byte row key is stored 16 times both on disk and in memory. This leads to several scalability problems, especially due to memory pressure inside Region Servers and the increased number of objects that HBase has to handle. ---
Is that true? Means that long row keys and many columns should be avoided? Yves [1] http://opentsdb.net/schema.html
