Dmitriy Govorukhin commented on IGNITE-11750: --------------------------------------------- [~sergey-chugunov] Thanks for the review! Merged to master. > Implement locked pages info dump for long-running B+Tree operations > ------------------------------------------------------------------- > > Key: IGNITE-11750 > URL: https://issues.apache.org/jira/browse/IGNITE-11750 > Project: Ignite > Issue Type: Improvement > Reporter: Alexey Goncharuk > Assignee: Dmitriy Govorukhin > Priority: Major > Fix For: 2.8 > > Time Spent: 0.5h > Remaining Estimate: 0h > > I've stumbled upon an incident where a batch of Ignite threads were hanging > on BPlusTree operations trying to acquire read or write lock on pages. From > the thread dump it is impossible to check if there is an issue with > {{OffheapReadWriteLock}} or there is a subtle deadlock in the tree. > I suggest we implement a timeout for page lock acquire and tracking of locked > pages. This should be relatively easy to implement in {{PageHandler}} (the > only thing to consider is performance degradation). If a timeout occurs, we > should print all the locks currently owned by a thread. This way we should be > able to determine if there is a deadlock in the {{BPlusTree}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
