Hey guys,
I am new to Ignite and trying to implement a custom counter. I read the
document and it seems like I can implement my counter in three different
ways so need some help figuring out which approach to take.
//business logic in pseudo code
Ignite ignite = Ignition.ignite();
IgniteTransactions transactions = ignite.transactions();
try (Transaction tx = transactions.txStart()) {
Account account = cache.get(accNbr);
long amount =account.getAmount()
account.updatedAmount(amount+10)
cache.put(accNbr,account);
tx.commit();
}
// end code
As far as I can tell, I can run this code
1) on the client side (maybe slow due to transaction?)
2) I can run it as IgniteCompute.affinityCall(...) on the grid itself. (I am
assuming I can start tx inside affinityCall)
3) Run this code as a Cluster Singleton behind a service
Please note that there could be multiple clients on different machines,
trying to update the same account so transaction locking is important. I am
leaning toward using affinityCall to implement this but was wondering
whether this is the correct approach?
Thanks
