backup_restore_* session settings

These settings are available in system.settings and are autogenerated from source.

backup_restore_batch_size_for_keeper_multi

Maximum size of batch for multi request to [Zoo]Keeper during backup or restore

backup_restore_batch_size_for_keeper_multiread

Maximum size of batch for multiread request to [Zoo]Keeper during backup or restore

backup_restore_failure_after_host_disconnected_for_seconds

If a host during a BACKUP ON CLUSTER or RESTORE ON CLUSTER operation doesn’t recreate its ephemeral ‘alive’ node in ZooKeeper for this amount of time then the whole backup or restore is considered as failed. This value should be bigger than any reasonable time for a host to reconnect to ZooKeeper after a failure. Zero means unlimited.

backup_restore_finish_timeout_after_error_sec

How long the initiator should wait for other host to react to the ‘error’ node and stop their work on the current BACKUP ON CLUSTER or RESTORE ON CLUSTER operation.

backup_restore_keeper_fault_injection_probability

Approximate probability of failure for a keeper request during backup or restore. Valid value is in interval [0.0f, 1.0f]

backup_restore_keeper_fault_injection_seed

0 - random seed, otherwise the setting value

backup_restore_keeper_max_retries

Max retries for [Zoo]Keeper operations in the middle of a BACKUP or RESTORE operation. Should be big enough so the whole operation won’t fail because of a temporary [Zoo]Keeper failure.

backup_restore_keeper_max_retries_while_handling_error

Max retries for [Zoo]Keeper operations while handling an error of a BACKUP ON CLUSTER or RESTORE ON CLUSTER operation.

backup_restore_keeper_max_retries_while_initializing

Max retries for [Zoo]Keeper operations during the initialization of a BACKUP ON CLUSTER or RESTORE ON CLUSTER operation.

backup_restore_keeper_retry_initial_backoff_ms

Initial backoff timeout for [Zoo]Keeper operations during backup or restore

backup_restore_keeper_retry_max_backoff_ms

Max backoff timeout for [Zoo]Keeper operations during backup or restore

Cloud default value: 60000.

backup_restore_keeper_value_max_size

Maximum size of data of a [Zoo]Keeper’s node during backup

backup_restore_s3_retry_attempts

Setting for Aws::Client::RetryStrategy, Aws::Client does retries itself, 0 means no retries. It takes place only for backup/restore.

backup_restore_s3_retry_initial_backoff_ms

Initial backoff delay in milliseconds before the first retry attempt during backup and restore. Each subsequent retry increases the delay exponentially, up to the maximum specified by backup_restore_s3_retry_max_backoff_ms

backup_restore_s3_retry_jitter_factor

Jitter factor applied to the retry backoff delay in Aws::Client::RetryStrategy during backup and restore operations. The computed backoff delay is multiplied by a random factor in the range [1.0, 1.0 + jitter], up to the maximum backup_restore_s3_retry_max_backoff_ms. Must be in [0.0, 1.0] interval

backup_restore_s3_retry_max_backoff_ms

Maximum delay in milliseconds between retries during backup and restore operations.
