This is a newbie question.


What is in a HBase block index entry?


My guess is that it's one of these:


1.      all key components: rowkey + column family + column qualifier +

2.      all key components except for column family (since the index is in a
HFile that is a part of the storage for a column family): rowkey + column
qualifier + timestamp

3.      rowkey only


I've tried to find the information, But the articles only say that it
contains a 'key'. For me as a newbie, it is confusing since in a KeyValue
the all key components comprise the 'key', while a rowkey is also a 'key'.
