---------------------------------------
Attachment: ItReadOnlyTxStartTest.java
> RO transactions establish readTs on first read and not on start
> ---------------------------------------------------------------

> Key: IGNITE-24142
> URL: https://issues.apache.org/jira/browse/IGNITE-24142
> Project: Ignite
> Issue Type: Bug
> Reporter: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
> Attachments: ItReadOnlyTxStartTest.java
>
>
> Client transactions are lazy. This means that a client RO transaction
> establishes its readTs on first data node access, not on start. But in the
> embedded mode, readTs is established on transaction start.
> # It seems weird that our APIs behave differently
> # Trying to imagine myself in the user's shoes, it seems very
> counterintuivite that creation of a transaction does not establish the
> readTs. Take a look at the reproducer scenario: as a user, I would expect the
> test to pass in both cases (embedded/client)
> Attaching a reproducer. It passes for embedded mode but fails for client. The
> scenario is:
> # Start an RO tx (tx1)
> # Make an implicit put under k1
> # Read k1 in tx1 and expect to see nothing
