MySQL Error 1614: Distributed Transaction Deadlock Rollback
Description
This error signifies that a deadlock has been detected within a branch of an XA (distributed) transaction. When this occurs, the specific transaction branch involved is automatically rolled back by MySQL to resolve the contention. It typically happens in environments where multiple independent transactions are coordinated across different resource managers, leading to a circular dependency for locks.
Error Message
XA_RBDEADLOCK: Transaction branch was rolled back: deadlock was detected
Known Causes
3 known causesConflicting Lock Acquisition
Multiple XA transaction branches attempt to acquire locks on shared resources in an incompatible order, creating a cyclic dependency.
Inefficient XA Branch Design
Poorly designed XA branches hold locks for extended periods or involve too many resource modifications, increasing contention.
High Concurrency on Shared Data
Numerous concurrent XA operations frequently access and modify the same data rows or tables, leading to lock conflicts.
