Hi, Any pointers on how to optimize hbase for random access? My understanding is that HFile is decent at random access. Why doesn't it use memory mapped I/O? (my reading on it indicated it uses "something like NIO"). I'd like my entire table to be distributed across region servers, so that random reads are quickly served by a region server without having to transfer a block from HDFS. Is this the right approach? I would have thought that some sort of memory-mapped region file would be perfect for this. Anyway, just looking to understand the best practice(s).
