Alexey Goncharuk created IGNITE-7698: ----------------------------------------
Summary: Page read during replacement should be outside of segment write lock Key: IGNITE-7698 URL: https://issues.apache.org/jira/browse/IGNITE-7698 Project: Ignite Issue Type: Improvement Components: persistence Affects Versions: 2.1 Reporter: Alexey Goncharuk Fix For: 2.5 When a page is acquired, if it needs to be read from disk, we read it inside the segment write lock which blocks other threads from acquiring pages that are already in memory. This can be easily avoided: once we initialized the page's being loaded RW lock, we can immediately acquire the write lock - no deadlocks can happen here. Afterwards, we can release the segment write lock and read the page. The change seems to be very local. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
