python - Python, SQLAlchemy, how to insert queries in an efficient way with only one commit instruction

Question

I am working with SQLAlchemy and my insert function works correctly. However, i want and i need it to be efficient, therefore since i am inserting inside a "for loop", i would like to commit just once at the end of my program execution.

I am not sure, this kind of thinking applies to SQLAlchemy, so please advice me on the right, efficient way of doing it.

my code will call a insert_query function from a for loop. I do not return the query object that is created inside the function call.

def insert_query(publicId, secret, keyhandle, secretobj):

    #creates the query object 
    sql = secretobj.insert().values(public_id=publicId, keyhandle=keyhandle, secret=secret)
    #insert the query
    result = connection.execute(sql)

    return result

#####################
# CALL INSERT BELOW #
#####################


#walk across the file system to do some stuff
for root, subFolders, files in os.walk(path):
    if files:

        do_some_stuff_that_produce_output_for_insert_query()

        #########################
        # here i call my insert #
        #########################
        if not insert_query(publicId, secret, keyhandle, secretobj):
            print "WARNING: could not insert %s" % publicId


#close sqlalchemy
connection.close()
