Hi, All, Our use case requires to persist a stream into system like HBase. The stream data is in format of <timestamp, value>. In other word, timestamp is used as rowkey. We want to explore whether HBase is suitable for such kind of data.
The problem is that the domain of row key (or timestamp) grow constantly. For example, given 3 nodes, n1 n2 n3, they are resp. hosting row key partition [0,4], [5, 9], [10,12]. Currently it is the last node n3 who is busy receiving upcoming writes (of row key 13 and 14). This continues until the region reaches max size 5 (that is, partition grows to [10,14]) and potentially splits. I am not expert on HBase split, but I am wondering after split, will the new writes still go to node n3 (for [10,14]) or the write stream can be intelligently redirected to other less busy node, like n1. In case HBase can't do things like this, how easy is it to extend HBase for such functionality? Thanks... Yun
