Dear Experts,
We want to add a column on table size of 1.5TB, we have to perform this activity with minimal downtime.
What are the best practises to add a column on huge table ?
How much time alter statement will take to add column ?
Any alternate solution other than alter statement to add column ?
Will adding a new column on a huge table generate huge WAL files ?
Thanks and Best Regards,
Akther
