Massimo,
Would you mind giving a more in depth example on distributed transactions
with postgres? I know web2py supports them, however there is not much
information on it. How would you accomplish a join across databases?
Is there an api to abstract this?
dba = DAL('postgres...')
dbb = DAL('postgrse...')
dba.define_table('customers'....)
dba.define_table('employees'....)
dbb.define_table('products'....)
dbb.define_table('sales'.....)
db = DISTRIBUTED_DAL(dba, dbb)
rows = db(db.customers.id == request.vars.cust_id)(db.sales.id ==
request.vars.sale_id).select()
for row in rows:
print row.customer.name, row.customer.address, row.sale.time,
row.sale.product.name
