            Unable to find Databricks spark sql avro shaded jars in any public maven repository
            Asked 2022-Feb-19 at 15:54

            We are trying to create avro record with confluent schema registry. The same record we want to publish to kafka cluster.

            To attach schema id to each records (magic bytes) we need to use--
            to_avro(Column data, Column subject, String schemaRegistryAddress)

            To automate this we need to build project in pipeline & configure databricks jobs to use that jar.

            Now the problem we are facing in notebooks we are able to find a methods with 3 parameters to it.
            But the same library when we are using in our build downloaded from https://mvnrepository.com/artifact/org.apache.spark/spark-avro_2.12/3.1.2 its only having 2 overloaded methods of to_avro

            Is databricks having some other maven repository for its shaded jars?

            No, these jars aren't published to any public repository. You may check if the databricks-connect provides these jars (you can get their location with databricks-connect get-jar-dir), but I really doubt in that.

            Another approach is to mock it, for example, create a small library that will declare a function with specific signature, and use it for compilation only, don't include into the resulting jar.

            How can I read and decode AVRO messages from Kafka along with their associated kafka key using Benthos?
            Asked 2022-Feb-12 at 00:12

            I am using Benthos to read AVRO-encoded messages from Kafka which have the kafka_key metadata field set to also contain an AVRO-encoded payload. The schemas of these AVRO-encoded payloads are stored in Schema Registry and Benthos has a schema_registry_decode processor for decoding them. I'm looking to produce an output JSON message for each Kafka message containing two fields, one called content containing the decoded AVRO message and the other one called metadata containing the various metadata fields collected by Benthos including the decoded kafka_key payload.

            Debugging a Google Dataflow Streaming Job that does not work expected
            Asked 2022-Jan-26 at 19:14

            I am following this tutorial on migrating data from an oracle database to a Cloud SQL PostreSQL instance.

            I am using the Google Provided Streaming Template Datastream to PostgreSQL

            At a high level this is what is expected:

            1. Datastream exports in Avro format backfill and changed data into the specified Cloud Bucket location from the source Oracle database
            2. This triggers the Dataflow job to pickup the Avro files from this cloud storage location and insert into PostgreSQL instance.

            When the Avro files are uploaded into the Cloud Storage location, the job is indeed triggered but when I check the target PostgreSQL database the required data has not been populated.

            When I check the job logs and worker logs, there are no error logs. When the job is triggered these are the logs that logged:

            This answer is accurate as of 19th January 2022.

            Upon manual debug of this dataflow, I found that the issue is due to the dataflow job is looking for a schema with the exact same name as the value passed for the parameter databaseName and there was no other input parameter for the job using which we could pass a schema name. Therefore for this job to work, the tables will have to be created/imported into a schema with the same name as the database.

            However, as @Iñigo González said this dataflow is currently in Beta and seems to have some bugs as I ran into another issue as soon as this was resolved which required me having to change the source code of the dataflow template job itself and build a custom docker image for it.

            2.7.7 is the version that is then currently chosen automatically (with Spring Boot version 2.5.5).

            Using Kafka Streams with Serdes that rely on schema references in the Headers
            Asked 2022-Jan-11 at 00:23

            I'm trying to use Kafka Streams to perform KTable-KTable foreign key joins on CDC data. The data I will be reading is in Avro format, however it is serialized in a manner that wouldn't be compatible with other industry serializer/deserializers (ex. Confluent schema registry) because the schema identifiers are stored in the headers.

            When I setup my KTables' Serdes, my Kafka Streams app runs initially, but ultimately fails because it internally invokes the Serializer method with byte[] serialize(String topic, T data); and not a method with headers (ie. byte[] serialize(String topic, Headers headers, T data) in the wrapping serializer ValueAndTimestampSerializer. The Serdes I'm working with cannot handle this and throw an exception.

            First question is, does anyone know a way to implore Kafka Streams to call the method with the right method signature internally?

            I'm exploring approaches to get around this, including writing new Serdes that re-serialize with the schema identifiers in the message itself. This may involve recopying the data to a new topic or using interceptors.

            However, I understand ValueTransformer has access to headers in the ProcessorContext and I'm wondering if there might there be a faster way using transformValues(). The idea is to first read the value as a byte[] and then deserialize the value to my Avro class in the transformer (see example below). When I do this however, I'm getting an exception.

            I was able to solve this issue by first reading the input topic as a KStream and converting it to a KTable with different Serde as a second step, it seems State Stores are having the issue with not invoking serializer/deserializer method signatures with the headers.

            This is historic artifact of the fact that initially Spark Avro support was added by Databricks in their proprietary Spark Runtime as com.databricks.spark.avro format, when Sark Avro support was added to open-source Spark as avro format then, for backward compatibility, support of the com.databricks.spark.avro format was retained if spark.sql.legacy.replaceDatabricksSparkAvro.enabled property is set to true:

            If it is set to true, the data source provider com.databricks.spark.avro is mapped to the built-in but external Avro data source module for backward compatibility.
