Summary: Kafka Connect JDBC fails to create PostgreSQL table with default
boolean value in schema (was: Kafka Connect JDBC fails to create PostgreSQL
table with default boolean value)
> Kafka Connect JDBC fails to create PostgreSQL table with default boolean
> value in schema
> ----------------------------------------------------------------------------------------
>
> Key: KAFKA-8867
> URL: https://issues.apache.org/jira/browse/KAFKA-8867
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 2.3.0
> Reporter: Tudor
> Priority: Major
>
> The `CREATE TABLE ..` statement generated for JDBC sink connectors when
> configured with `auto.create: true` generates field declarations that do not
> conform to allowed PostgreSQL syntax when considering fields of type boolean
> with default values.
> Example record value Avro schema:
> {code:java}
> {
> "namespace": "com.test.avro.schema.v1",
> "type": "record",
> "name": "SomeEvent",
> "fields": [
> {
> "name": "boolean_field",
> "type": "boolean",
> "default": false
> }
> ]
> }
> {code}
> The connector task fails with:
> {code:java}
> ERROR WorkerSinkTask{id=test-events-sink-0} RetriableException from SinkTask:
> (org.apache.kafka.connect.runtime.WorkerSinkTask:551)
> org.apache.kafka.connect.errors.RetriableException: java.sql.SQLException:
> org.postgresql.util.PSQLException: ERROR: column "boolean_field" is of type
> boolean but default expression is of type integer
> Hint: You will need to rewrite or cast the expression.
