All DSP releases prior to DSP 1.4.0 use Gravity, a Kubernetes orchestrator, which has been announced end-of-life. We have replaced Gravity with an alternative component in DSP 1.4.0. Therefore, we will no longer provide support for versions of DSP prior to DSP 1.4.0 after July 1, 2023. We advise all of our customers to upgrade to DSP 1.4.0 in order to continue to receive full product support from Splunk.
Get data from Apache Pulsar
Use the Apache Pulsar source function to get data from an Apache Pulsar topic.
Prerequisites
Before you can use this function, you must create a connection. See Create a DSP connection to Apache Pulsar in the Connect to Data Sources and Destinations with the manual. When configuring this source function, set the connection_id
argument to the ID of that connection.
Function output schema
This function outputs records with the schema described in the following table.
Key | Description |
---|---|
key | The key of the record as a string. |
value | The payload of the record in bytes. |
topic | The name of the Pulsar topic where the record is stored, given as a string. |
messageId | The message ID of the record, given as a string. |
The following is an example of a typical record from the pulsar
function:
{ "key": "my-key", "value": "aGVsbG8gd29ybGQ=", "topic": "my-pulsar-topic", "messageId": 1:24 }
Required arguments
- connection_id
- Syntax: string
- Description: The ID of your Pulsar connection.
- Example in Canvas View: my-pulsar-connection
- topic
- Syntax: string
- Description: The name of the Pulsar topic.
- Example in Canvas View: my-pulsar-topic
SPL2 example
When working in the SPL View, you can write the function by providing the arguments in this exact order.
| from pulsar("my-connection-id", "my-topic") |...;
Alternatively, you can use named arguments to declare arguments in any order. The following SPL2 example uses named arguments to specify the topic
argument before the connection_id
argument.
| from pulsar(topic: "my-topic", connection_id: "my-connection-id") |...;
If you want to use a mix of unnamed and named arguments in your functions, you must list all unnamed arguments in the correct order before providing the named arguments.
