<h2 id="cloud_mode">

</h2>

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

Cloud mode

Cloud default value: `1`.

<h2 id="cloud_mode_engine">
  cloud\_mode\_engine
</h2>

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

The engine family allowed in Cloud.

* 0 - allow everything
* 1 - rewrite DDLs to use \*ReplicatedMergeTree
* 2 - rewrite DDLs to use SharedMergeTree
* 3 - rewrite DDLs to use SharedMergeTree except when explicitly passed remote disk is specified
* 4 - same as 3, plus additionally use Alias instead of Distributed (the Alias table will point to the destination table of the Distributed table, so it will use the corresponding local table)

UInt64 to minimize public part

Cloud default value: `2`.
