Question on concurrent update

Hi, All

    Let two concurrent clients update values of different qualifiers
of the same column family of the same row.  I guess that both
qualifiers will be updated properly. Is it correct?

Thank you for your cooperation,
M.

Yes.  Each client will hold a lock on the row while its updating its column.
