QUESTION

I would like to enable Flink to read from Pulsar

Asked 2020-Nov-14 at 19:08

I’m new to Pulsar!

Now, I am trying to implement these codes( https://flink.apache.org/2019/05/03/pulsar-flink.html ) in Scala. However, I can’t find some classes(e.g. PulsarSourceBuild). How can I do them in Scala? Where should I check?

PulsarSourceBuilder is from Pulsar

I'd suggest adding this to your pom:

QUESTION

How should I define Flink's Schema to read Protocol Buffer data from Pulsar

Asked 2020-Jul-30 at 12:01

I am using Pulsar-Flink to read data from Pulsar in Flink. I am having difficulty when the data's format is Protocol Buffer.

In the GitHub top page, Pulsar-Flink is using SimpleStringSchema. However, seemingly it does not comply with Protocol Buffer officially. Does anyone know how to deal with the data format? How should I define the schema?

You should implement your own DeserializationSchema. Let's assume that you have a protobuf message Address and have generated the respective Java class. Then the schema should look like the following:

Install pulsar-flink

To build the Pulsar Flink connector for reading data from Pulsar or writing the results to Pulsar, follow these steps. After the Pulsar Flink connector is installed, a JAR package that contains all the dependencies is generated in both the local Maven repository and the target directory.
Check out the source code. git clone https://github.com/streamnative/pulsar-flink.git cd pulsar-flink
Install the Docker. The Pulsar Flink connector uses Testcontainers for integration test. To run the integration test, ensure to install the Docker. For details about how to install the Docker, see here.
Set the Java version. Modify java.version and java.binary.version in pom.xml. Note Ensure that the Java version should be identical to the Java version for the Pulsar Flink connector.
Build the project. mvn clean install -DskipTests
Run the test. mvn clean install
