Internal Should not be instantiated by the user.
Optional Readonly collectionThe collection the command is being run on, if applicable.
Readonly commandThe command object. Equal to the response body of the HTTP request.
Note that this is the actual raw command object; it's not necessarily 1:1 with methods called on the collection/db.
For example, a deleteAll method on a collection will be translated into a deleteMany command, and a bulkWrite
method will be translated into a series of insertOne, updateOne, etc. commands.
{
insertOne: { document: { name: 'John' } }
}
Readonly commandThe command name.
This is the key of the command object. For example, if the command object is
{ insertOne: { document: { name: 'John' } } }, the command name is insertOne.
Meaning, abstracted commands like bulkWrite, or deleteAll will be shown as their actual command equivalents.
Readonly keyspaceThe keyspace the command is being run in.
Readonly namespaceThe keyspace the command is being run in.
This is now a deprecated alias for the strictly equivalent CommandEvent.keyspace, and will be removed in an upcoming major version.

Readonly timeoutThe timeout for the command, in milliseconds.
Readonly urlThe URL the command is being sent to.
Emitted when a command is started, before the initial HTTP request is made.
Note that these emit real commands, not any abstracted commands like "bulkWrite", "insertMany", or "deleteAll", which have to be translated into appropriate Data API commands.
See CommandEvent for more information about all the common properties available on this event.
