Hi Ionut,

Yes, this is correct. Transaction is thread-local and I don't think what you
propose is feasible, because someone has to coordinate the transaction.
Map-reduce approach works for data processing, but not for transactional
updates.

I understand that you don't know the keys in advance, but you can load them
using SQL query like 'select _key from ... where ...' which will return only
keys, not values. You can then update them using entry processor in a single
transaction.

As for the invocation on the client, this is a know issue:
https://issues.apache.org/jira/browse/IGNITE-3471. I should be fixed soon.
