  • PXC#2480: Failed to replicate CURRENT_USER() involved ALTER TABLE

  • CURRENT_USER refers to current running active user.

  • When the said statement is replicated through TOI and is executed
    using applier thread then CURRENT_USER() context is not valid.
    (as applier thread is running in background).

  • This can cause error/assert (starting 5.7). While we wait for
    proper fix from upstream we should block ALTER operation involving
    CURRENT_USER().
