MongoDB

To use username/password or LDAP authentication, enter the required credentials in one of the following ways:

Connection string

Enter credentials in the connection string on the MongoDB tab.

To enter credentials for username/password authentication, enter the username and password before the host name. Use the following format:

mongodb://username:password@host[:port][/[database][?options]]

To enter credentials for LDAP authentication, enter the username and password before the host name, and set the authMechanism option to PLAIN. Use the following format:

mongodb://username:password@host[:port][/[database]?authMechanism=PLAIN

Credentials tab

Select either the Username/Password or LDAP authentication type on the Credentials tab. When using LDAP authentication, you also choose between server-driven or plain authentication.

Then, you specify the username and password for the authentication type.

When you use a date or Object ID field, specify a timestamp to use as the initial offset. Object ID fields include an embedded timestamp that the origin uses to determine where in the collection to begin reading. When you define the initial offset for a date or Object ID field, use the following format:

YYYY-MM-DD HH:mm:ss

You can use the following MongoDB read preferences:

• Primary - Requires reading from the primary member.
• Primary Preferred - Prefers reading from the primary, but allows reads from a secondary member.
• Secondary - Requires reading from a secondary member.
• Secondary Preferred - Prefers reading from a secondary, but allows reads from a primary when necessary.
• Nearest - Reads from the member with the least network latency.

MongoDB origin events can be used in any logical way. For example:

• With the Pipeline Finisher executor to stop the pipeline and transition the pipeline to a Finished state when the origin completes processing available data.

  When you restart a pipeline stopped by the Pipeline Finisher executor, the origin continues processing from the last-saved offset unless you reset the origin.

  For an example, see Stopping a Pipeline After Processing All Available Data.

• With a destination to store event information.

  For an example, see Preserving an Audit Trail of Events.

The MongoDB BSON Timestamp is a MongoDB data type that includes a timestamp and ordinal as follows:

<BSON Timestamp field name>:Timestamp(<timestamp>, <ordinal>)

<BSON Timestamp field name>{MAP}:
    Timestamp{DATETIME}:<UTC timestamp>
    Ordinal{INTEGER}:<integer ordinal>

For example, a Transaction BSON timestamp of (1485449409, 1), is converted to the following Transaction map field:

"Transaction":{
    "Timestamp":Jan 26, 2016 14:50:09PM
    "Ordinal":1
}
