     [ https://issues.apache.org/jira/browse/IGNITE-17261?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexander Lapin updated IGNITE-17261:
-------------------------------------
    Description: Because of lock-free nature RO reads might interact with writeIntents, meaning that such intents should be either evaluated as committed, aborted or pending. In order to perform writeIntent resolution it's required to check txnState along with [adjusting HLC timestamp|https://issues.apache.org/jira/browse/IGNITE-17222] on txnStates group.
