All,
Just wanting to be safe...
Suppose I have a Column family that has the following columns:
foo and bar.
(CF:foo, CF:bar)
So in my table I have a row:
Row_key | CF:foo CF:bar
Alpha | foo_val1 bar_val1
Later, I update the row with new data including a new column CF:retz
So I have the following:
Row_key | CF:foo CF:bar CF:retz
Alpha | foo_valX bar_valX some_value
Later, I'm asked to restore the row from a back up.
So when I re-insert the row with the row_key Alpha
( Alpha | foo_val1 bar_val1)
will I have :
Row_key | CF:foo CF:bar
Alpha | foo_val1 bar_val1
or:
Row_key | CF:foo CF:bar CF:retz
Alpha | foo_val1 bar_val1 some_value
I imagine that when I write out a column family, I'm inserting the whole row so
I wouldn't see anything in the column (CF:retz) but I want to do a sanity check.
Thx
-Mike
