These settings are available in [system.merge\_tree\_settings](/docs/reference/system-tables/merge_tree_settings) and are autogenerated from ClickHouse source.

<h2 id="max_replicated_fetches_network_bandwidth">
  max\_replicated\_fetches\_network\_bandwidth
</h2>

<SettingsInfoBlock type="UInt64" default_value="0" />

Limits the maximum speed of data exchange over the network in bytes per
second for [replicated](/docs/reference/engines/table-engines/mergetree-family/replication)
fetches. This setting is applied to a particular table, unlike the
[`max_replicated_fetches_network_bandwidth_for_server`](/docs/reference/settings/merge-tree-settings/max-replicated#max_replicated_fetches_network_bandwidth)
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.

<h2 id="max_replicated_logs_to_keep">
  max\_replicated\_logs\_to\_keep
</h2>

<SettingsInfoBlock type="UInt64" default_value="1000" />

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.

<h2 id="max_replicated_merges_in_queue">
  max\_replicated\_merges\_in\_queue
</h2>

<SettingsInfoBlock type="UInt64" default_value="1000" />

How many tasks of merging and mutating parts are allowed simultaneously in
ReplicatedMergeTree queue.

<h2 id="max_replicated_merges_with_ttl_in_queue">
  max\_replicated\_merges\_with\_ttl\_in\_queue
</h2>

<SettingsInfoBlock type="UInt64" default_value="1" />

How many tasks of merging parts with TTL are allowed simultaneously in
ReplicatedMergeTree queue.

<h2 id="max_replicated_mutations_in_queue">
  max\_replicated\_mutations\_in\_queue
</h2>

<SettingsInfoBlock type="UInt64" default_value="8" />

How many tasks of mutating parts are allowed simultaneously in
ReplicatedMergeTree queue.

<h2 id="max_replicated_sends_network_bandwidth">
  max\_replicated\_sends\_network\_bandwidth
</h2>

<SettingsInfoBlock type="UInt64" default_value="0" />

Limits the maximum speed of data exchange over the network in bytes per
second for [replicated](/docs/reference/engines/table-engines/mergetree-family/replacingmergetree)
sends. This setting is applied to a particular table, unlike the
[`max_replicated_sends_network_bandwidth_for_server`](/docs/reference/settings/merge-tree-settings/max-replicated#max_replicated_sends_network_bandwidth)
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

`max_replicated_sends_network_bandwidth_for_server` setting.
