distributed_replica_error_cap
- Type: unsigned int
- Default value: 1000
The error count of each replica is capped at this value, preventing a single replica from accumulating too many errors.

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.
