type AutoEncryptionOptions added in v1.2.0 

type AutoEncryptionOptions struct {
	KeyVaultClientOptions *ClientOptions
	KeyVaultNamespace     string
	KmsProviders          map[string]map[string]interface{}
	SchemaMap             map[string]interface{}
	BypassAutoEncryption  *bool
	ExtraOptions          map[string]interface{}
}

AutoEncryptionOptions represents options used to configure auto encryption/decryption behavior for a mongo.Client instance.

Automatic encryption is an enterprise only feature that only applies to operations on a collection. Automatic encryption is not supported for operations on a database or view, and operations that are not bypassed will result in error. Too bypass automatic encryption for all operations, set BypassAutoEncryption=true.

Auto encryption requires the authenticated user to have the listCollections privilege action.

If automatic encryption fails on an operation, use a MongoClient configured with bypassAutoEncryption=true and use ClientEncryption.encrypt() to manually encrypt values.

Enabling Client Side Encryption reduces the maximum document and message size (using a maxBsonObjectSize of 2MiB and maxMessageSizeBytes of 6MB) and may have a negative performance impact.

func AutoEncryption added in v1.2.0 

func AutoEncryption() *AutoEncryptionOptions

AutoEncryption creates a new AutoEncryptionOptions configured with default values.

func MergeAutoEncryptionOptions added in v1.2.0 

func MergeAutoEncryptionOptions(opts ...*AutoEncryptionOptions) *AutoEncryptionOptions

func (*AutoEncryptionOptions) SetBypassAutoEncryption added in v1.2.0 

func (a *AutoEncryptionOptions) SetBypassAutoEncryption(bypass bool) *AutoEncryptionOptions

SetBypassAutoEncryption specifies whether or not auto encryption should be done.

If this is unset or false and target mongo.Client being configured has an unlimited connection pool size (i.e. maxPoolSize=0), it is reused in the process of auto encryption. Otherwise, if the target mongo.Client has a limited connection pool size, a separate internal mongo.Client is used (and created if necessary). The internal mongo.Client may be shared for key vault operations (if KeyVaultClient is unset). The internal mongo.Client is configured with the same options as the target mongo.Client except minPoolSize is set to 0 and AutoEncryptionOptions is omitted.

func (*AutoEncryptionOptions) SetExtraOptions added in v1.2.0 

func (a *AutoEncryptionOptions) SetExtraOptions(extraOpts map[string]interface{}) *AutoEncryptionOptions

SetExtraOptions specifies a map of options to configure the mongocryptd process.

func (*AutoEncryptionOptions) SetKeyVaultClientOptions added in v1.2.0 

func (a *AutoEncryptionOptions) SetKeyVaultClientOptions(opts *ClientOptions) *AutoEncryptionOptions

SetKeyVaultClientOptions specifies options for the client used to communicate with the key vault collection.

If this is set, it is used to create an internal mongo.Client. Otherwise, if the target mongo.Client being configured has an unlimited connection pool size (i.e. maxPoolSize=0), it is reused to interact with the key vault collection. Otherwise, if the target mongo.Client has a limited connection pool size, a separate internal mongo.Client is used (and created if necessary). The internal mongo.Client may be shared during automatic encryption (if BypassAutomaticEncryption is false). The internal mongo.Client is configured with the same options as the target mongo.Client except minPoolSize is set to 0 and AutoEncryptionOptions is omitted.

func (*AutoEncryptionOptions) SetKeyVaultNamespace added in v1.2.0 

func (a *AutoEncryptionOptions) SetKeyVaultNamespace(ns string) *AutoEncryptionOptions

SetKeyVaultNamespace specifies the namespace of the key vault collection. This is required.

func (*AutoEncryptionOptions) SetKmsProviders added in v1.2.0 

func (a *AutoEncryptionOptions) SetKmsProviders(providers map[string]map[string]interface{}) *AutoEncryptionOptions

SetKmsProviders specifies options for KMS providers. This is required.

func (*AutoEncryptionOptions) SetSchemaMap added in v1.2.0 

func (a *AutoEncryptionOptions) SetSchemaMap(schemaMap map[string]interface{}) *AutoEncryptionOptions

SetSchemaMap specifies a map from namespace to local schema document. Schemas supplied in the schemaMap only apply to configuring automatic encryption for client side encryption. Other validation rules in the JSON schema will not be enforced by the driver and will result in an error.

Supplying a schemaMap provides more security than relying on JSON Schemas obtained from the server. It protects against a malicious server advertising a false JSON Schema, which could trick the client into sending unencrypted data that should be encrypted.

type BucketOptions added in v0.1.0 

type BucketOptions struct {
	// The name of the bucket. The default value is "fs".
	Name *string

	// The number of bytes in each chunk in the bucket. The default value is 255 KiB.

	ResumeAfter interface{}

	// If specified, the change stream will only return changes that occurred at or after the given timestamp. This
	// option is only valid for MongoDB versions >= 4.0. If this is specified, ResumeAfter and StartAfter must not be
	// set.
	StartAtOperationTime *primitive.Timestamp

	// A document specifying the logical starting point for the change stream. This is similar to the ResumeAfter
	// option, but allows a resume token from an "invalidate" notification to be used. This allows a change stream on a

ClientOptions contains options to configure a Client instance. Each option can be set through setter functions. See documentation for each setter function for an explanation of the option.

func Client added in v0.1.0 

func Client() *ClientOptions

Client creates a new ClientOptions instance.

func MergeClientOptions added in v0.1.0 

func MergeClientOptions(opts ...*ClientOptions) *ClientOptions

MergeClientOptions combines the given *ClientOptions into a single *ClientOptions in a last one wins fashion. The specified options are merged with the existing options on the client, with the specified options taking precedence.

func (*ClientOptions) ApplyURI added in v1.0.0 

func (c *ClientOptions) ApplyURI(uri string) *ClientOptions

ApplyURI parses the given URI and sets options accordingly. The URI can contain host names, IPv4/IPv6 literals, or an SRV record that will be resolved when the Client is created. When using an SRV record, TLS support is implictly enabled. Specify the "tls=false" URI option to override this.

If the connection string contains any options that have previously been set, it will overwrite them. Options that correspond to multiple URI parameters, such as WriteConcern, will be completely overwritten if any of the query parameters are specified. If an option is set on ClientOptions after this method is called, that option will override any option applied via the connection string.

If the URI format is incorrect or there are conflicing options specified in the URI an error will be recorded and can be retrieved by calling Validate.

For more information about the URI format, see https://docs.mongodb.com/manual/reference/connection-string/. See mongo.Connect documentation for examples of using URIs for different Client configurations.

func (*ClientOptions) GetURI added in v1.3.1 

func (c *ClientOptions) GetURI() string

GetURI returns the original URI used to configure the ClientOptions instance. If ApplyURI was not called during construction, this returns "".

func (*ClientOptions) SetAppName added in v0.1.0 

func (c *ClientOptions) SetAppName(s string) *ClientOptions

SetAppName specifies an application name that is sent to the server when creating new connections. It is used by the server to log connection and profiling information (e.g. slow query logs). This can also be set through the "appName" URI option (e.g "appName=example_application"). The default is empty, meaning no app name will be sent.

func (*ClientOptions) SetAuth added in v0.1.0 

func (c *ClientOptions) SetAuth(auth Credential) *ClientOptions

SetAuth specifies a Credential containing options for configuring authentication. See the options.Credential documentation for more information about Credential fields. The default is an empty Credential, meaning no authentication will be configured.

func (*ClientOptions) SetAutoEncryptionOptions added in v1.2.0 

func (c *ClientOptions) SetAutoEncryptionOptions(opts *AutoEncryptionOptions) *ClientOptions

SetAutoEncryptionOptions specifies an AutoEncryptionOptions instance to automatically encrypt and decrypt commands and their results. See the options.AutoEncryptionOptions documentation for more information about the supported options.

func (*ClientOptions) SetCompressors added in v1.0.0 

func (c *ClientOptions) SetCompressors(comps []string) *ClientOptions

SetCompressors sets the compressors that can be used when communicating with a server. Valid values are:

1. "snappy" - requires server version >= 3.4

2. "zlib" - requires server version >= 3.6

  1. "zstd" - requires server version >= 4.2, and driver version >= 1.2.0 with cgo support enabled or driver version >= 1.3.0 without cgo

If this option is specified, the driver will perform a negotiation with the server to determine a common list of of compressors and will use the first one in that list when performing operations. See https://docs.mongodb.com/manual/reference/program/mongod/#cmdoption-mongod-networkmessagecompressors for more information about configuring compression on the server and the server-side defaults.

This can also be set through the "compressors" URI option (e.g. "compressors=zstd,zlib,snappy"). The default is an empty slice, meaning no compression will be enabled.

func (*ClientOptions) SetConnectTimeout added in v0.1.0 

func (c *ClientOptions) SetConnectTimeout(d time.Duration) *ClientOptions

SetConnectTimeout specifies a timeout that is used for creating connections to the server. If a custom Dialer is specified through SetDialer, this option must not be used. This can be set through ApplyURI with the "connectTimeoutMS" (e.g "connectTimeoutMS=30") option. If set to 0, no timeout will be used. The default is 30 seconds.

func (*ClientOptions) SetDialer added in v0.1.0 

func (c *ClientOptions) SetDialer(d ContextDialer) *ClientOptions

SetDialer specifies a custom ContextDialer to be used to create new connections to the server. The default is a net.Dialer with the Timeout field set to ConnectTimeout. See https://golang.org/pkg/net/#Dialer for more information about the net.Dialer type.

func (*ClientOptions) SetDirect added in v1.0.0 

func (c *ClientOptions) SetDirect(b bool) *ClientOptions

SetDirect specifies whether or not a direct connect should be made. If set to true, the driver will only connect to the host provided in the URI and will not discover other hosts in the cluster. This can also be set through the "directConnection" URI option. This option cannot be set to true if multiple hosts are specified, either through ApplyURI or SetHosts, or an SRV URI is used.

As of driver version 1.4, the "connect" URI option has been deprecated and replaced with "directConnection". The "connect" URI option has two values:

1. "connect=direct" for direct connections. This corresponds to "directConnection=true".

2. "connect=automatic" for automatic discovery. This corresponds to "directConnection=false"

If the "connect" and "directConnection" URI options are both specified in the connection string, their values must not conflict. Direct connections are not valid if multiple hosts are specified or an SRV URI is used. The default value for this option is false.

func (*ClientOptions) SetDisableOCSPEndpointCheck added in v1.4.0 

func (c *ClientOptions) SetDisableOCSPEndpointCheck(disableCheck bool) *ClientOptions

SetDisableOCSPEndpointCheck specifies whether or not the driver should reach out to OCSP responders to verify the certificate status for certificates presented by the server that contain a list of OCSP responders.

If set to true, the driver will verify the status of the certificate using a response stapled by the server, if there is one, but will not send an HTTP request to any responders if there is no staple. In this case, the driver will continue the connection even though the certificate status is not known.

This can also be set through the tlsDisableOCSPEndpointCheck URI option. Both this URI option and tlsInsecure must not be set at the same time and will error if they are. The default value is false.

func (*ClientOptions) SetHeartbeatInterval added in v0.1.0 

func (c *ClientOptions) SetHeartbeatInterval(d time.Duration) *ClientOptions

SetHeartbeatInterval specifies the amount of time to wait between periodic background server checks. This can also be set through the "heartbeatIntervalMS" URI option (e.g. "heartbeatIntervalMS=10000"). The default is 10 seconds.

func (*ClientOptions) SetHosts added in v0.1.0 

func (c *ClientOptions) SetHosts(s []string) *ClientOptions

SetHosts specifies a list of host names or IP addresses for servers in a cluster. Both IPv4 and IPv6 addresses are supported. IPv6 literals must be enclosed in '[]' following RFC-2732 syntax.

Hosts can also be specified as a comma-separated list in a URI. For example, to include "localhost:27017" and "localhost:27018", a URI could be "mongodb://localhost:27017,localhost:27018". The default is ["localhost:27017"]

func (*ClientOptions) SetLocalThreshold added in v0.1.0 

func (c *ClientOptions) SetLocalThreshold(d time.Duration) *ClientOptions

SetLocalThreshold specifies the width of the 'latency window': when choosing between multiple suitable servers for an operation, this is the acceptable non-negative delta between shortest and longest average round-trip times. A server within the latency window is selected randomly. This can also be set through the "localThresholdMS" URI option (e.g. "localThresholdMS=15000"). The default is 15 milliseconds.

func (*ClientOptions) SetMaxConnIdleTime added in v0.1.0 

func (c *ClientOptions) SetMaxConnIdleTime(d time.Duration) *ClientOptions

SetMaxConnIdleTime specifies the maximum amount of time that a connection will remain idle in a connection pool before it is removed from the pool and closed. This can also be set through the "maxIdleTimeMS" URI option (e.g. "maxIdleTimeMS=10000"). The default is 0, meaning a connection can remain unused indefinitely.

func (*ClientOptions) SetMaxPoolSize added in v0.1.0

Username: the username for authentication. This can also be set through the URI as a username:password pair before the first @ character. For example, a URI for user "user", password "pwd", and host "localhost:27017" would be "mongodb://user:pwd@localhost:27017". This is optional for X509 authentication and will be extracted from the client certificate if not specified.

Password: the password for authentication. This must not be specified for X509 and is optional for GSSAPI authentication.

PasswordSet: For GSSAPI, this must be true if a password is specified, even if the password is the empty string, and false if no password is specified, indicating that the password should be taken from the context of the running process. For other mechanisms, this field is ignored.
