Hi,
I am trying to sink the data from kafka topic using ksqldb to Redis. Inorder to achieve this, I am using redis-source-sink connector(6.6.8) Redis Connector (Source and Sink) by Redis | Confluent Hub
Below are the properties used.
“name”: “kafka-connect-redis-10”,
“config”: {
“connector.class”: “com.redis.kafka.connect.RedisSinkConnector”,
“tasks.max”: “1”,
“redis.type”:“HASH”,
“redis.uri”:““uri_of_sentinel_server””,
“redis.username”: “username”,
“redis.password”: “”,
“key.converter”: “org.apache.kafka.connect.storage.StringConverter”,
“value.converter”: “io.confluent.connect.avro.AvroConverter”,
“value.converter.enhanced.avro.schema.support”: “true”,
“value.converter.schema.registry.url”: “http://:”,
“redis.operation.timeout.ms”: 10000,
“redis.database”:3,
“topics”: “santoshtopic”
}
The above property was used to create the connector instance. When the data is being pushed on to kafka topic,
I should be able to see the same records being sinked into Redis.But, I end up getting the below error.
Help here would be really appreciated since we are blocked.
Note : We need to connect via Sentinel URI
