These settings are available in [system.settings](/docs/reference/system-tables/settings) and are autogenerated from [source](https://github.com/ClickHouse/ClickHouse/blob/master/src/Core/Settings.cpp).

<h2 id="send_profile_events">
  send\_profile\_events
</h2>

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

<VersionHistory rows={[{"id": "row-1","items": [{"label": "25.11"},{"label": "1"},{"label": "New setting. Whether to send profile events to the clients."}]}]} />

Enables or disables sending of [ProfileEvents](/docs/resources/develop-contribute/native-protocol/server#profile-events) packets to the client.

This can be disabled to reduce network traffic for clients that do not require profile events.

Possible values:

* 0 — Disabled.
* 1 — Enabled.

<h2 id="send_progress_in_http_headers">
  send\_progress\_in\_http\_headers
</h2>

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

Enables or disables `X-ClickHouse-Progress` HTTP response headers in `clickhouse-server` responses.

For more information, read the [HTTP interface description](/docs/concepts/features/interfaces/http).

Possible values:

* 0 — Disabled.
* 1 — Enabled.

<h2 id="send_table_structure_on_insert_with_inline_data">
  send\_table\_structure\_on\_insert\_with\_inline\_data
</h2>

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

<VersionHistory rows={[{"id": "row-1","items": [{"label": "26.5"},{"label": "1"},{"label": "New setting to control whether server sends table structure for INSERT queries with inline data."}]}]} />

If disabled and the INSERT query contains inline data, the server will not send the table structure and column defaults back to the client over the native protocol. Instead, the server will parse the inline data itself. This can improve performance for many small inserts over the native protocol.

<h2 id="send_timeout">
  send\_timeout
</h2>

<SettingsInfoBlock type="Seconds" default_value="300" />

Timeout for sending data to the network, in seconds. If a client needs to send some data but is not able to send any bytes in this interval, the exception is thrown. If you set this setting on the client, the 'receive\_timeout' for the socket will also be set on the corresponding connection end on the server.
