YildizDB -> Kafka

Currently not supported!

Kafka -> YildizDB

const { runSinkConnector } = require("yildiz-kafka-connect");
runSinkConnector(config, [], onError).then(config => {
    //runs forever until: config.stop();
});

Kafka -> YildizDB (with custom topic (no source-task topic))

const { runSinkConnector, ConverterFactory } = require("yildiz-kafka-connect");
 
const etlFunc = (messageValue, callback) => {
 
    return callback(null, {
        id: messageValue.payload.id,
        name: messageValue.payload.name,
        info: messageValue.payload.info
    });
};
 
const converter = ConverterFactory.createSinkSchemaConverter({}, etlFunc);
 
runSinkConnector(config, [converter], onError).then(config => {
    //runs forever until: config.stop();
});
 
/*
    this example would be able to store kafka message values
    that look like this (so completely unrelated to messages created by a default SourceTask)
    {
        payload: {
            id: 1,
            name: "first item",
            info: "some info"
        },
        type: "publish"
    }
