(See Section 19.1.4.1, “Replication Mode Concepts”.) The writeset implementation employed by MySQL (and NDB Cluster) uses hash-based conflict detection based on matching 64-bit row hashes of relevant table and index values. This detects reliably ...To use this functionality with NDB Cluster, it is necessary that the replica be configured to use multiple worker ...
