[jira] [Updated] (IGNITE-17638) Implement Txn state map to optimize write intent resolution
[ https://issues.apache.org/jira/browse/IGNITE-17638?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sergey Uttsel updated IGNITE-17638:
-----------------------------------
Description:
Need to implement Txn state map which contains txId -> (txState, txCoordinatorAdress, commitTimestamp).
This map will be located on all nodes in replication group (primary and followers) and updated on modification command. On cleanupCommand need to set commitTimestamp.
Txn state map optimizes write intent resolution. If commitTs <= readTs then RO transaction treat a write intent as committed.
