Hello Rosen,
Lets say you are working against mysql...
2000 records in table 1 and 500.000 records in table 2 is few
information... and it's working 'cause you don't have 50000
records in table 1 and 3.000.000 records in table 2.
But, I personally advise you to listen what Peter is telling you.

If you lock a table, then all process trying to access the table
locked will have to wait until the table is released.
But you'll have to deal with times of expiration.
