Lets assume a table test
cf:a cf:b yy:a kk:cat
"com.cnn.news" zubrava10 sobaka foobar
"ch.main.users" - - - purrpurr
And the first cell ("zubrava") has 10 versions (10 timestamps) ("zubrava1", "zubrava2"...)
How data of this table will be stored on disk?
I mean is the primary index always
("row","column_family:column",timestamp) ?
So 10 versions of the same row for 10 timestamps will be stored together? How the entire table is stored?
Is scan for all values of given column is as fast as in column-oriented models?
SELECT cf:a from test
