Hello again!

I've read/browsed through your datastore comparison pdf, and these are
my two takeaways:

1. MySQL scales the best and provides comparable performance to
"native" GAE (up to 48 nodes); other back-ends (Cassandra, Voldermort,
etc.) are slow under heavy load;

2. you don't have indexes yet and thus if our app uses (hundreds of)
millions of entities and is query-heavy, AppScale is not suitable for
us now.

Did I get it correctly?

Best regards,
MG

Hello,
The MySQL cluster implementation does use indexes, but the other datastores
do not. We're currently working on getting index support for cassandra
which is of major importance to get scalable queries.

The numbers you see are just a snapshot in time. Since then we've updates
many of the datastores, and they've all gotten better.
