### Search before asking - [X] I had searched in the [feature](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement. ### Description When testing data sync from Kafka to any sink database(e.g. Mysql, PG, clickhouse,,.etc), I find an "issue" and it may need to be enhanced. The issue is that: the default key/value's deserializer when cosuming Kafka records is [ByteArrayDeserializer] , Which means no matter you override "kakfa.config" or use default property in your job configuration file the returned data is byteArrays's binding(key,value). This implement looks like a bit inconvenient because byeArrary is not a standard datatype in most polular databases and user must convert it before writing data into database. ### Usage Scenario A simple example configuration file is as below: # Defining the runtime environment env { # You can set flink configuration here execution.parallelism = 4 job.mode = "STREAMING" } source{ Kafka { format = json topic = "sensor_data" bootstrap.servers = "localhost:9092" result_table_name = "middle_sensor_tbl" schema = { fields { id = "string" timestamp = "bigint" temperature_c = "decimal(38,20)" } } start_mode = "earliest" kafka.config = { auto.offset.reset = "earliest" enable.auto.commit = "true" max.poll.records = "1000" session.timeout.ms = "60000" key.deserializer = org.apache.kafka.common.serialization.StringDeserializer } } } transform { # If you would like to get more information about how to configure seatunnel and see full list of transform plugins, # please go to https://seatunnel.apache.org/docs/transform-v2/sql } # query = "insert into sensor_data(id, timestamp, temperature_c) values(?,?,?)" sink { jdbc { source_table_name = "middle_sensor_tbl" url = "jdbc:postgresql://localhost:6982/seatunnel_test" driver = "org.postgresql.Driver" database ="seatunnel_test" user = "seatunnel_test" password = "seatunnel_test_123" table = "sensor_data" batch_size = 10000 primary_keys = ["id"] query = "insert into sensor_data(id, timestamp, temperature_c) values(?,?,?)" } } ### Related issues No ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
