Methods

buildInfo

command

  • Execute a command

    The driver will ensure the following fields are attached to the command sent to the server:

    • lsid - sourced from an implicit session or options.session
    • $readPreference - defaults to primary or can be configured by options.readPreference
    • $db - sourced from the name of this database

    If the client has a serverApi setting:

    • apiVersion
    • apiStrict
    • apiDeprecationErrors

    When in a transaction:

    • readConcern - sourced from readConcern set on the TransactionOptions
    • writeConcern - sourced from writeConcern set on the TransactionOptions

    Attaching any of the above fields to the command will have no effect as the driver will overwrite the value.
