  • Type: unsigned int
  • Default value: 1000

​
distributed_replica_error_half_life

  • Type: seconds
  • Default value: 60 seconds
Controls how fast errors in distributed tables are zeroed. If a replica is unavailable for some time, accumulates 5 errors, and distributed_replica_error_half_life is set to 1 second, then the replica is considered normal 3 seconds after the last error. See also:

​

  • Type: unsigned int
  • Default value: 0
