-------------------------------------
Labels: ignite-3 transaction3_rw (was: ignite-3)
> Enlist txnState into single parition only
> -----------------------------------------
>
> Key: IGNITE-16882
> URL: https://issues.apache.org/jira/browse/IGNITE-16882
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexander Lapin
> Assignee: Alexander Lapin
> Priority: Major
> Labels: ignite-3, transaction3_rw
>
> Currenlly txState(PENDING|ABORTED|COMMITED) is updated within all enlisted
> partitions which is not an atomic solution. According to new tx design it's
> required to replicate tx state with single partition only.
> As a prerequisite persisted replicated TxnStateStore should be introduced
> https://issues.apache.org/jira/browse/IGNITE-15931
> Such introduction will allow to rework existing tx implementaiton in order to
> store txState only within single partition.
> instead of using
> {code:java}
> partId = abs(txId.hashCode() % partCnt) {code}
> we might use any other idempotent funtion, e.g. first partition of first
> enlisted key.
> Tx.Phase1
