Tudor-Alexandru Voicu updated KAFKA-8867:
-----------------------------------------
Description:
The `CREATE TABLE ..` statement generated for 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 of source message values Avro schema for input topic:
{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.
