max_replicated_fetches_network_bandwidth
Limits the maximum speed of data exchange over the network in bytes per
second for replicated
fetches. This setting is applied to a particular table, unlike the
max_replicated_fetches_network_bandwidth_for_server
setting, which is applied to the server.
You can limit both server network and network for a particular table, but for
this the value of the table-level setting should be less than server-level
one. Otherwise the server considers only the
max_replicated_fetches_network_bandwidth_for_server setting.
The setting isn’t followed perfectly accurately.
Possible values:
- Positive integer.
0— Unlimited.
Default value: 0.
Usage
Could be used for throttling speed when replicating data to add or replace new nodes.
max_replicated_logs_to_keep
How many records may be in the ClickHouse Keeper log if there is inactive replica. An inactive replica becomes lost when when this number exceed.
Possible values:
- Any positive integer.
max_replicated_merges_in_queue
How many tasks of merging and mutating parts are allowed simultaneously in ReplicatedMergeTree queue.
max_replicated_merges_with_ttl_in_queue
How many tasks of merging parts with TTL are allowed simultaneously in ReplicatedMergeTree queue.
max_replicated_mutations_in_queue
How many tasks of mutating parts are allowed simultaneously in ReplicatedMergeTree queue.
max_replicated_sends_network_bandwidth
Limits the maximum speed of data exchange over the network in bytes per
second for replicated
sends. This setting is applied to a particular table, unlike the
max_replicated_sends_network_bandwidth_for_server
setting, which is applied to the server.
You can limit both server network and network for a particular table, but
for this the value of the table-level setting should be less than
server-level one. Otherwise the server considers only the
max_replicated_sends_network_bandwidth_for_server setting.
