Hi folks- The HBase Book/RefGuide has been updated http://hbase.apache.org/book.html
In particular, there is now a description of the compaction selection algorithm…. http://hbase.apache.org/book.html#compaction … many thanks to Nicholas for proving insight into this. Also, a section for coprocessors was created in Arch/RegionServer has been added, pointing to the great blog entry on the subject. Eventually this can be merged to the book, but at least there's a link to it now. Doug Meil Chief Software Architect, Explorys doug.m...@explorys.com
