Configuration Properties

The Salesforce Platform Events Source Connector can be configured using a variety of configuration properties.

Connection

salesforce.consumer.key

The consumer key for the OAuth application.

  • Type: string
  • Importance: high
salesforce.consumer.secret

The consumer secret for the OAuth application.

  • Type: password
  • Importance: high
salesforce.password

The Salesforce password the connector should use.

  • Type: password
  • Importance: high
salesforce.password.token

The Salesforce security token associated with the username.

  • Type: password
  • Importance: high
salesforce.username

The Salesforce username the connector should use.

  • Type: string
  • Importance: high
salesforce.instance

The URL of the Salesforce endpoint to use. The default is blank. This directs the connector to use the endpoint specified in the authentication response.

http.proxy

The HTTP(S) proxy host and port the connector should use when talking to Salesforce. This defaults to a blank string, which corresponds to not using a proxy.

  • Type: string
  • Default: null
  • Valid Values: Of the form <host>:<port> where <host> is a valid hostname or IP address, and <port> is a valid port number
  • Importance: medium
connection.timeout

The amount of time to wait while connecting to the Salesforce streaming endpoint.

  • Type: long
  • Default: 30000
  • Valid Values: [5000,…,600000]
  • Importance: low
curl.logging

If enabled the logs will output the equivalent curl commands. This is a security risk because your authorization header is displayed in the log file. Use at your own risk.

  • Type: boolean
  • Default: false
  • Importance: low
request.max.retries.time.ms

The maximum time in milliseconds that the connector continue retry requests to Salesforce that fail because of network issues once authentication succeeds. The backoff period for each retry attempt uses a randomization function that grows exponentially. But, if the total time spent retrying the request exceeds this duration (15 minutes by default), retries stop and the request fails. This will likely result in task failure.

  • Type: long
  • Default: 900000
  • Valid Values: [1,…]
  • Importance: low
salesforce.version

The version of the Salesforce API to use.

  • Type: string
  • Default: latest
  • Valid Values: Matches regex( ^(latest|[d.]+)$ )
  • Importance: low

Apache Kafka®

kafka.topic

The Kafka topic to write the SalesForce data to. This is a template driven by the data returned by Salesforce. Any field in the schema can be used but you should always pick a value that is guaranteed to exist. _EventType and _ObjectType are two metadata fields that are included on every record. For example you could put update and deletes in a different topic by using salesforce.${_ObjectType}.${_EventType}

  • Type: string
  • Importance: high
kafka.topic.lowercase

Flag to determine if the Kafka topic should be lowercase.

  • Type: boolean
  • Default: true
  • Importance: high

Salesforce Streaming

salesforce.platform.event.name

The Salesforce platform event name to subscribe to. The Event name should end with ‘__e’ suffix. For example: LoginEvent__e

  • Type: string
  • Valid Values: Matches regex( .*__e$ )
  • Importance: high
salesforce.initial.start

Specify the initial starting point for the connector for replaying events. Use all to send a replayId of -2 to Salesforce that replays all events from last 24 hours, or use latest to send a replayId of -1 to Salesforce that plays only new incoming events that arrive after the connector has started. The default is latest in case there are more enqueued events than might be allowed by API limits.

  • Type: string
  • Default: latest
  • Valid Values: Matches regex( ^(all|latest)$ )
  • Importance: high

Confluent Platform license

confluent.topic.bootstrap.servers

A list of host/port pairs to use for establishing the initial connection to the Kafka cluster used for licensing. All servers in the cluster will be discovered from the initial connection. This list should be in the form <code>host1:port1,host2:port2,…</code>. Since these servers are just used for the initial connection to discover the full cluster membership (which may change dynamically), this list need not contain the full set of servers (you may want more than one, though, in case a server is down).

  • Type: list
  • Importance: high
confluent.topic

Name of the Kafka topic used for Confluent Platform configuration, including licensing information.

  • Type: string
  • Default: _confluent-command
  • Importance: low
confluent.topic.replication.factor

The replication factor for the Kafka topic used for Confluent Platform configuration, including licensing information. This is used only if the topic does not already exist, and the default of 3 is appropriate for production use. If you are using a development environment with less than 3 brokers, you must set this to the number of brokers (often 1).

  • Type: int
  • Default: 3
  • Importance: low

Confluent license properties

Note

This connector is proprietary and requires a license. The license information is stored in the _confluent-command topic. If the broker requires SSL for connections, you must include the security-related confluent.topic.* properties as described below.

confluent.license

Confluent issues enterprise license keys to each subscriber. The license key is text that you can copy and paste as the value for confluent.license. A trial license allows using the connector for a 30-day trial period. A developer license allows using the connector indefinitely for single-broker development environments.

If you are a subscriber, please contact Confluent Support for more information.

  • Type: string
  • Default: “”
  • Valid Values: Confluent Platform license
  • Importance: high
confluent.topic.ssl.truststore.location

The location of the trust store file. For example, confluent.topic.ssl.truststore.location=/kfkapps/Kafka/certs/MSPKI/CA1/ec_kfk_dev.ca1.cert.jks.

  • Type: string
  • Default: null
  • Importance: high
confluent.topic.ssl.truststore.password

The password for the trust store file. If a password is not set access to the truststore is still available, but integrity checking is disabled.

  • Type: password
  • Default: null
  • Importance: high
confluent.topic.ssl.keystore.location

The location of the key store file. This is optional for client and can be used for two-way authentication for client. For example, confluent.topic.ssl.keystore.location=/kfkapps/Kafka/certs/MSPKI/Truststore/DEV_cacerts.jks.

  • Type: string
  • Default: null
  • Importance: high
confluent.topic.ssl.keystore.password

The store password for the key store file. This is optional for client and only needed if ssl.keystore.location is configured.

  • Type: password
  • Default: null
  • Importance: high
confluent.topic.ssl.key.password

The password of the private key in the key store file. This is optional for client.

  • Type: password
  • Default: null
  • Importance: high
confluent.topic.security.protocol

Protocol used to communicate with brokers. Valid values are: PLAINTEXT, SSL, SASL_PLAINTEXT, SASL_SSL.

  • Type: string
  • Default: “PLAINTEXT”
  • Importance: medium

License topic configuration

A Confluent enterprise license is stored in the _confluent-command topic. This topic is created by default and contains the license that corresponds to the license key supplied through the confluent.license property.

Note

No public keys are stored in Kafka topics.

The following describes how the default _confluent-command topic is generated under different scenarios:

  • A 30-day trial license is automatically generated for the _confluent command topic if you do not add the confluent.license property or leave this property empty (for example, confluent.license=).
  • Adding a valid license key (for example, confluent.license=<valid-license-key>) adds a valid license in the _confluent-command topic.

Here is an example of the minimal properties for development and testing.

You can change the name of the _confluent-command topic using the confluent.topic property (for instance, if your environment has strict naming conventions). The example below shows this change and the configured Kafka bootstrap server.

confluent.topic=foo_confluent-command
confluent.topic.bootstrap.servers=localhost:9092

The example above shows the minimally required bootstrap server property that you can use for development and testing. For a production environment, you add the normal producer, consumer, and topic configuration properties to the connector properties, prefixed with confluent.topic..

Overriding Default Configuration Properties

You can override the replication factor using confluent.topic.replication.factor. For example, when using an Kafka cluster as a destination with less than three brokers (for development and testing) you should set the confluent.topic.replication.factor property to 1.

You can override producer-specific properties by using the confluent.topic.producer. prefix and consumer-specific properties by using the confluent.topic.consumer. prefix.

You can use the defaults or customize the other properties as well. For example, the confluent.topic.client.id property defaults to the name of the connector with -licensing suffix. You can specify the configuration settings for brokers that require SSL or SASL for client connections using this prefix.

You cannot override the cleanup policy of a topic because the topic always has a single partition and is compacted. Also, do not specify serializers and deserializers using this prefix; they are ignored if added.
