----------------------------------------
Assignee: Mikhail Efremov
> Retry implicit transactions when primary replica failed or moved
> ----------------------------------------------------------------
>
> Key: IGNITE-21500
> URL: https://issues.apache.org/jira/browse/IGNITE-21500
> Project: Ignite
> Issue Type: Improvement
> Reporter: Denis Chudov
> Assignee: Mikhail Efremov
> Priority: Major
> Labels: ignite-3
>
> *Motivation*
> Implicit transactions are created without a transaction from the client point
> of view (the transaction is created inside the library and is not exposed
> outside).
> A failure to execute such transaction because of the primary replica related
> exceptions (PrimaryReplicaMissException, etc.). should not result in the
> users seeing them.
> Instead, retrying these transactions will likely to succeed.
> *Definition of done*
> An implicit transaction that failed to execute because of
> PrimaryReplicaMissException, PrimaryReplicaAwaitException,
> TransactionExceptions with messages like "Failed to get the primary replica",
> "Failed to resolve the primary replica node"
> should be retried.
> If it is not possible to await for the primary replica, the transaction will
> fail. The primary replica failure exceptions are not propagated to the users
> in cases of implicit transactions - a different exception is thrown instead.
> *Implementation detail*
> There might be some difficulties with implicit scan and implicit direct RO
> transactions. No issues with plain implicit RW transactions is expected.
