Pavel Tupitsyn commented on IGNITE-26619:
-----------------------------------------
Will be potentially fixed by IGNITE-26621 in Java client, but we still need to
propagate *observableTimestamp* with all read operations in other clients.
> Implicit client ro tx does not include observableTimestamp

> Key: IGNITE-26619
> URL: https://issues.apache.org/jira/browse/IGNITE-26619
> Project: Ignite
> Issue Type: Bug
> Components: thin clients ai3
> Affects Versions: 3.0
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Priority: Critical
> Labels: ignite-3
> Fix For: 3.1
>
>
> * In thin client protocol, explicit read-only transactions propagate
> *observableTimestamp*
> * However, read operations without an explicit transaction *do not* send
> *observableTimestamp*, so implicit RO TX has different behavior
> ** Inconsistent behavior can be observed when consequent read requests for
> the same key go to different nodes. This can happen on connection failure or
> due to round-robing in thin client when primary replica connection is not
> available
