URL: https://github.com/apache/camel-kafka-connector/issues/1487
Hello,
I'm trying to get the Cassandra sink connector to work with a JSON string
produced to a Kafka topic. I've managed to get the connector to add rows to my
table when producing the Kafka message:
```
["1","John",1670428382089]
```
But would instead like to produce messages on to the topic in the following
format:
```
{
"id" : "1",
"name" : "John",
"created_at" : 1670428382089
}
```
I've attempted to use
`value.converter=org.apache.kafka.connect.json.JsonConverter` in my sink
properties, but receive the exception: `NoTypeConversionAvailableException: No
type converter available to convert from type: java.util.HashMap to the
required type: java.io.InputStream`.
Is it possible to achieve this with the Camel Cassandra sink connector?
___
Cassandra table:
```cql
USE connect;
CREATE TABLE person (
id TEXT PRIMARY KEY,
name TEXT,
created_at TIMESTAMP
);
```
Sink properties:
```properties
name=person-cassandra-sink-connector
topics=person
tasks.max=1
connector.class=org.apache.camel.kafkaconnector.cassandrasink.CamelCassandrasinkSinkConnector
value.converter=org.apache.kafka.connect.storage.StringConverter
camel.kamelet.cassandra-sink.connectionHost=cassandra
camel.kamelet.cassandra-sink.connectionPort=9042
camel.kamelet.cassandra-sink.keyspace=connect
camel.kamelet.cassandra-sink.query=insert into person(id, name, created_at)
values (?, ?, ?)
camel.kamelet.cassandra-sink.prepareStatements=false
```
