/**

* Constructs a create command.
|

*
|
|
* Supported options:
|
|
*
|
|
* * autoIndexId (boolean): Specify false to disable the automatic creation
|
|
* of an index on the _id field. For replica sets, this option cannot be
|
|
* false. The default is true.
|
|
*
|
|
* This option has been deprecated since MongoDB 3.2. As of MongoDB 4.0,
|
|
* this option cannot be false when creating a replicated collection
|
|
* (i.e. a collection outside of the local database in any mongod mode).
|
|
*
|
|
* * capped (boolean): Specify true to create a capped collection. If set,
|
|
* the size option must also be specified. The default is false.
|
|
*
|
|
* * collation (document): Collation specification.
|
|
*
|
|
* This is not supported for server versions < 3.4 and will result in an
|
|
* exception at execution time if used.
|
|
*
|
|
* * flags (integer): Options for the MMAPv1 storage engine only. Must be a
|
|
* bitwise combination CreateCollection::USE_POWER_OF_2_SIZES and
|
|
* CreateCollection::NO_PADDING. The default is
|
|
* CreateCollection::USE_POWER_OF_2_SIZES.
|
|
*
|
|
* * indexOptionDefaults (document): Default configuration for indexes when
|
|
* creating the collection.
|
|
*
|
|
* * max (integer): The maximum number of documents allowed in the capped
|
|
* collection. The size option takes precedence over this limit.
|
|
*
|
|
* * maxTimeMS (integer): The maximum amount of time to allow the query to
|
|
* run.
|
|
*
|
|
* * session (MongoDB\Driver\Session): Client session.
|
|
*
|
|
* Sessions are not supported for server versions < 3.6.
|
|
*
|
|
* * size (integer): The maximum number of bytes for a capped collection.
|
|
*
|
|
* * storageEngine (document): Storage engine options.
|
|
*
|
|
* * typeMap (array): Type map for BSON deserialization. This will only be
|
|
* used for the returned command result document.
|
|
*
|
|
* * validationAction (string): Validation action.
|
|
*
|
|
* * validationLevel (string): Validation level.
|
|
*
|
|
* * validator (document): Validation rules or expressions.
|
|
*
|
|
* * writeConcern (MongoDB\Driver\WriteConcern): Write concern.
|
|
*
|
|
* This is not supported for server versions < 3.4 and will result in an
|
|
* exception at execution time if used.
