These question are better for BIgtable forum than Django forum. But If I consider moving to Bigtable in future, I need some visibility into
1) Is BIGTABLE fully acid complaint? from what I have read it is not atleast in some cases. 2) in what cases is it not acid complaint? Moving from RDMBS world what should I watch out for or compensate for? services which I take for granted in good RDMBS like Oracle, but are missing here. 3) Should I even move from RDBMS to it? Is it even a good subsititute for RDBMS for transaction processing systems? It seems it is good for Data warehousing, Historical data, data mining etc. 4) How do we do backups? It is new paradigm from RDBMS and requires some new thinking from my side as well. thanks Ashish On Apr 8, 10:43 am, "Eduardo O.
