Roman Kondakov created IGNITE-9591: -------------------------------------- Summary: MVCC: Do small write operations under the read lock. Key: IGNITE-9591 URL: https://issues.apache.org/jira/browse/IGNITE-9591 Project: Ignite Issue Type: Improvement Components: mvcc Reporter: Roman Kondakov
There are several operations in MVCC flow which can be done under the page read lock instead of write lock. For example, setting xid_max on a datarow. It is safe, because races are possible only between concurrent transactions, which are not visible to each other. See {{MvccMarkUpdatedHandler}} and other similar handlers in this class. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
