Hello, it seems that sstable index file only contains key/position and
each sstable doesn't have column index. So how does range slice query
work? Does it iterate through every key in the range for column
name/value comparison?
The column index is in the SSTable. It does not appear to necessarily be
a complete index of the columns.

3. Start indexing based on column family comparator
3.2 Iterate over columns until getColumnIndexSize() is exceeded (default
is 64KB)
...
4. Serialize each IndexInfo object - (firstname is last column name
before exceeded, and lastname is the existing column name)
