TransactionOptimisticException: Failed to prepare transaction,
read/write conflict
Hi,
Ignite version: 2.6.0
I am getting following exception while committing a transaction inside
IgniteRunnable task.
Transaction is
try (Transaction tx =
transactions.txStart(TransactionConcurrency.OPTIMISTIC,
TransactionIsolation.SERIALIZABLE)) {
....
..
}
As per the ignite doc
<https://apacheignite.readme.io/docs/concurrency-modes-and-isolation-levels#section-optimistic-transactions>
if
the transaction isolation level is serializable,
Ignite will fail a transaction at the commit stage if the Ignite engine
detects that at least one of the entries used as part of the initiated
transaction has been modified.
But inside transaction I am just reading SubscriptionData from
Sunsbscription cache, I am not modifying this data inside transaction. Also
this SubscriptionData is not being modified in some other request
outside the mentioned transaction.
Then what could be the reason for this transaction failure?

Re: TransactionOptimisticException: Failed to prepare transaction,
read/write conflict
Posted by Denis Magda <dm...@apache.org>.
This is not supposed to happen if a record is not updated in parallel.
Could you prepare a reproducer?
In general, an optimistic transaction fails if any of the records within a
transaction gets modified concurrently.
