salesforce-kafka-connect

Greenkeeper badge Kafka Connect connector for Salesforce with bulk options configuration support.

Build Status

Use API

npm install --save salesforce-kafka-connect

salesforce -> kafka

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

kafka -> salesforce

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

kafka -> salesforce (with custom topic (no source-task topic))

const { runSinkConnector, ConverterFactory } = require("salesforce-kafka-connect");

const etlFunc = (messageValue, callback) => {

    //type is an example json format field
    if (messageValue.type === "publish") {
        return callback(null, {
            id: messageValue.payload.id,
            name__c: messageValue.payload.name,
            info__c: messageValue.payload.info
        });
    }

    if (messageValue.type === "unpublish") {
        return callback(null, null); //null value will cause deletion
    }

    callback(new Error("unknown messageValue.type"));
};

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__c: "first item",
            info__c: "some info"
        },
        type: "publish"
    }
*/
