Vladislav Pyatkov commented on IGNITE-17938: -------------------------------------------- LGTM This patch is solved the issue, but we are still waiting longer in some operation when enlist partition concurrently in one transaction. > Implement thread-safe enlisting of a primary node into a transaction > -------------------------------------------------------------------- > > Key: IGNITE-17938 > URL: https://issues.apache.org/jira/browse/IGNITE-17938 > Project: Ignite > Issue Type: Bug > Reporter: Vladislav Pyatkov > Assignee: Alexander Lapin > Priority: Major > Labels: ignite-3 > Time Spent: 10m > Remaining Estimate: 0h > > Before to send a replica request, we try to determine a primary node. If the > replication group is not used before, primary replica is choosing as a > current leader for the replication group and will be enlisted only when the > request is sent and handled. > If several replica requests are handled simultaneously, in the same > circumstances (primary is not enlisted for the replication group), a > coordinator node can try to enlist several different primaries for the group. > Before, we do nothing to resolve this situation, so last primary replaces > previous one. > But the right solution do not allow situation where we have several primaries > for the group in one transaction. Required to check that the primary node is > the same for all requests and throw an exception if this is not right. -- This message was sent by Atlassian Jira (v8.20.10#820010)
