Configuring Confluent Kafka Accounts

You can configure your Confluent Kafka accounts in SnapLogic using either the Designer or Manager.

Using SnapLogic Designer

Drag a Kafka Snap to the Canvas and click the Snap to open its settings. Click the Account tab. You can now either use an existing account or create a new one.

Selecting an existing account

SnapLogic organizes and displays all accounts to which you have access, sorting them by account type and location. To select an existing account:

  1. Click the  icon to view the accounts to which you have access and select the account that you want to use.
  2. Click  to save the Snap settings.

Creating an account

  1. Click Add Account in the Account Reference dialog.
  2. Select the Location in which you want to create the account, select the account type, and click ContinueThe Add Account dialog associated with the account type appears.


  3. Enter the required account details. For detailed guidance on how to provide information associated with each account type, use the following links:
    • Kafka Account
    • Kafka Kerberos Account
    • Kafka SSL Account

      Enter additional information on this account in the Notes field of the Info tab. This will help you–and other users–understand the purpose of the account, especially if there are multiple accounts of the same type.

  4. Click Validate to verify the account, if the account type supports validation.

  5. Click Apply to complete configuring the Kafka account.

Using SnapLogic Manager

Use Manager to create accounts without associating them immediately with Pipelines.

Accounts in SnapLogic are associated with projects. You can use accounts created in other projects only if you have at least Read access to them.

  1. In the left pane, browse to the project in which you want to create the account and click Create Account Confluent Kafka, followed by the appropriate account type.


  2. Repeat the steps numbered 3 through 5 in the Creating an account section.

    Avoid updating account credentials while Pipelines using that account are executing. This may lead to unexpected results, including locking your account.

Account Encryption

Standard EncryptionIf you use Standard Encryption, the High sensitivity settings under Enhanced Encryption are used.
Enhanced Encryption

If the account you are using has the Enhanced Encryption feature, the account fields are encrypted for each sensitivity level as shown below:

  • High: [None]
  • Medium + High: [None]
  • Low + Medium + High[None]

Troubleshooting

ErrorReasonResolution
The message size exceeds the default message limit.By default, the message size limit is 1 MB. To increase this limit, you must change a few settings in the Confluent Kafka broker and Snap account. On the Confluent Kafka broker side, set the server.properties and producer.properties to a size larger than your message size.

In the  Advanced Kafka Properties field of the applicable Snap account settings, you must add  max.request.size and set it to a size larger than your message size. 

For example, you can increase the message size limit to 15 MB in any one of the following ways:

  1. Assign the following values to properties in Confluent Kafka broker > server.properties:
    • message.max.bytes = 15728640
    • replica.fetch.max.bytes = 15728640
    • max.request.size = 15728640
    • fetch.message.max.bytes = 15728640
  2. In Confluent Kafka broker > producer.properties, set:
    • max.request.size = 15728640
  3. In the required Snap account settings, add the following Key/Value pair in the Advanced Kafka Properties field:
    • max.request.size = 15728640

  • Improved the handling of interrupted/aborted Kafka Snaps to ensure proper clean-up of metrics.

  • Optimized the Kafka Producer Snap to initialize the Kafka API only if there is at least one input document.

  • Fixed the issue of account passwords being included in the log messages output of Kafka  Snaps. The password is now hidden in the logs for both Kafka Consumer and Kafka Producer Snaps.

  • Removed the Confluent prefix from the Snaps and accounts in the Snap Pack. However, the Snap Pack name continues to be Confluent Kafka Snap Pack.

  • Added the Wait For Full Count check box to the Kafka Consumer Snap to determine how a positive value for the Message Count field must be interpreted.

    • Enabled (by default): The Snap continues polling for messages until the specified count is reached.

    • Disabled: If the number of messages that are currently available is less than the specified count, then the Snap consumes the available messages and terminates.

      Known Issue

      The Wait For Full Count check box activates only when you provide a positive integer value in the Message Count field. However, it does not activate when you use an expression for Message Count even if the value evaluates to a positive number.

      Workaround: To activate this check box, temporarily replace the Message Count expression () with a positive integer, select the desired state for Wait For Full Count, and then restore the original value in the Message Count field.

  • Added support for writing and reading record headers.

    • The Kafka Producer Snap has a new Headers table to configure the Key, Value, and Serializer for each header to be written.

    • The Kafka Consumer Snap reads any headers present on the records it consumes. It provides two new fields to configure how the header values should be deserialized – Default Header Deserializer and Header Deserializers, for any headers that require a deserializer other than the default.

  • Added support for writing and reading each record’s timestamp.

    • The Kafka Producer Snap has a new Timestamp field that can be configured to set each record’s timestamp, which is the number of milliseconds since the epoch (00:00:00 UTC on January 1, 1970). This can be set to an expression that evaluates to a long integer, or a string that can be parsed as a long integer, or a date. If you specify no expression, or the value is empty, then the timestamp is set to the current time.

      The Timestamp field is relevant only if the Kafka topic is configured with message.timestamp.type = CreateTime (which is the default). For more information, see the official Kafka documentation.

    • The Kafka Consumer Snap has a new check box, Include Timestamp, which by default is disabled for backward compatibility. If enabled, the output for each record includes its timestamp in the metadata.

  • The Kafka Producer Snap has a new check box, Output Records, to determine the format of each output document when configured with an output view.

    • Disabled (by default): The Snap’s output includes only the basic metadata (topic, partition, offset) for each record, along with the original input document.

    • Enabled: Each output document contains a more complete representation of the record produced, including its key, value, headers, and timestamp.

  • The Kafka Consumer Snap has a new field, Output Mode, with two options:

    • One output document per record (the default): Every record received from Kafka has a corresponding output document.

    • One output document per batch: Preserves the batching of records as received from Kafka. Every poll that returns a non-empty set of records results in a single output document containing the list of records as batchbatch_size and batch_index. This mode is especially useful when Auto Commit is disabled and Acknowledge Mode is Wait after each batch of records, depending on the nature of the processing between the Kafka Consumer and the Kafka Acknowledge Snaps.

  • Removed the Add 1 to Offsets check box from the Kafka Consumer Snap.

  • Removed the Account tab from the Kafka Acknowledge Snap, because this Snap no longer needs an account.

    • Properties removed: Auto commit interval (msec), Standardize error output.
    • Diagnostic fields added in the metadata object in the Snap's output:
      • client_id: The unique ID assigned to a single Kafka consumer client instance. All documents written by a Consumer Snap during a single pipeline execution or validation will have the same value for this field.
      • batch_size: The number of messages in the batch of messages that the current message came from. Note that “batch” isn’t Kafka terminology; we’re using it to mean the set of messages received from the broker in a single call to Kafka’s poll method.
      • batch_index: The current batch number relative to a single consumer instance.  This number starts at 0 for the first batch and is only incremented for batches which contain at least one message.
      • record_index: The current record number relative to its batch.  The first message in a batch has an index of 0; the last has an index of batch_size - 1.
  • Confluent Kafka Acknowledge Snap: Added new property–Metadata path.
  • Confluent Kafka Producer Snap: Added new properties–Key serializer and Value serializer.
