Subject Re: Distributed transaction support in Ingnite

1. In write-behind mode database updates are not transactional. If you want
Ignite to maintain underlying Oracle transaction to make sure cache and DB
are always consistent, you need to use synchronous write-through. As for
compute, you can execute transaction within compute, but you can't do
compute inside a transaction like in your example above. Basically, the
whole transaction must be executed in a single thread, while compute can be
executed even on another node.

2. Load cache process is not triggered automatically, you need to start it
manually. Just call IgniteCache#loadCache method and Ignite will make sure
data is loaded on all nodes.
