Using following scenario:
- Started 5 nodes of 10.3
- Did Rolling Upgrade to 10.4
- Run following SQLs one of the nodes:
CREATE SEQUENCE Seq1_1 START WITH 1 INCREMENT BY 1;
|
CREATE TABLE Observation (Id int(11) NOT NULL, Place varchar(50) NOT NULL, BirdId int(11) NOT NULL,PRIMARY KEY (Id));
|
INSERT INTO Observation (Id, Place, BirdId) VALUES (NEXT VALUE FOR Seq1_1, 'Helsinki', 10);
|
INSERT INTO Observation (Id, Place, BirdId) VALUES (NEXT VALUE FOR Seq1_1, 'Espoo', 10);
|
INSERT INTO Observation (Id, Place, BirdId) VALUES (NEXT VALUE FOR Seq1_1, 'Kirkkonummi', 10);
|
INSERT INTO Observation (Id, Place, BirdId) VALUES (NEXT VALUE FOR Seq1_1, 'Hanko', 10);
|
drop sequence Seq1_1;
|
CREATE SEQUENCE Seq1_1 START WITH 1 INCREMENT BY 1;
|
INSERT INTO Observation (Id, Place, BirdId) VALUES (NEXT VALUE FOR Seq1_1, 'Helsinki', 10);
|
The result of last insert:
`ERROR 2013 (HY000): Lost connection to MySQL server during query`

With 10.3 cluster there is no such issue -> reusing sequence resulted with duplicated key error as expected.
