    if we are having a merge statement in the end instead of append or df.write statement then is there a way to handle this scenario?

    Is this possible on spark without databricks? Or redshift and glue?

      Yes it is possible in spark without databricks. Redshift and glue should have different options to handle this scenario

    In mergeschema, can we change the data type of existing column in Delta table like from integer to string?

    each time we require to run the create table statement when we start the cluster as data has already been written into it. Is there a way to avoid it?

      Create external table..read it in a dataframe ..on top of it create view...run that thing instead everytime....
