You need access to your Topology object in your Java/Scala/Kotlin code. How do I retrieve my Topology description? If the application is down, the topology disappears and it becomes redish, time to call the developers! Here is an example importing a Kafka Streams application using the application.id myapplicationid and exposing a endpoint /topology:Ĭonduktor will then monitor the endpoint and display a summary (topics in and out) in the main listing: Conduktor will automatically fetch it regularly, adapt the metrics accordingly, and warn you if it's down.by URL: paste the endpoint of your application exposing its topology.Static: paste your topology directly inside Conduktor.Specify the application.id of your application.To do so, go to the Kafka Streams menu and click on IMPORT TOPOLOGY, then: They generally work with many topics (in/out/internal/intermediates) and can be reset when you want to start it fresh again.Ĭonduktor can help you monitoring these applications, and the topics being used. Kafka Streams applications are outside of the scope of Kafka itself, they can be running anywhere. How to import a Topology inside Conduktor, and why? Add here the information from the Aiven Console that you noted down earlier, add the two files you downloaded, and specify a folder for. In the Add new Cluster screen, click the Aiven integration button. This way, you can monitor your application state, topics, statestores etc. In the Conduktor desktop application, click New Kafka Cluster in the main pane. It will start a typical Kafka Streams application and expose an HTTP API to be connected to Conduktor (optional). We're providing an example you can try and fork: It's possible to update a Connector by using this same wizard or simply by providing an updated JSON.Kafka Streams Where to start with Kafka Streams? When you pick a Sink or a Source connector type (or Create From JSON), you have access to a nice wizard properly organized and fully documented (just hover the property names).įor instance, here, one of the step of the Elasticsearch Sink Connector: You can also simply load a JSON to init the wizard: The available connector types depend on the Kafka Connect instance you're creating a connector. We provide a wizard to easily create connectors. Restart your Connector (re-create it), it will start from scratch.It is not meant for production workloads. Please note: Conduktor Playground is meant to help you learn, test, and get started with Kafka. Once you sign up for Conduktor you get two free Kafka clusters to use without any restrictions. Select the key and "RESET SOURCE OFFSETS" To help you get started quickly we created Conduktor Playground.Click Lookup and let Conduktor find the partition and latest value.my Kafka Connect offsets topic: "docker-connect-offsets".my connector name: "my-connector" which is already stopped (ie: removed).Summary Financials People Technology Signals & News Similar Companies. reset the source offsets: using Conduktor!Ĭonduktor will look for the partition containing the latest occurrence of your connector configuration, to know "where" to reset it. Conduktor is an Apache Kafka enterprise platform, most famous for its Kafka desktop application.change the Connector name: Kafka Connect won't find any existing state obviously.Unfortunately, removing a Connector does not delete its state from Kafka. Sometimes (mostly when testing), you want to reset a connector to start from "scratch", as it was the first time ever you've started it. Kafka Connect stores connectors state inside Kafka itself. UNASSIGNED: no worker is picking it up!.Restart a particular task of a ConnectorĪ connector and its tasks can have different states:.It's possible to restart a Connector or simply a task (or all tasks at once, different of a full connector restart). In the details, it's possible to look at which task failed and why: Here is a typical example with 6 Kafka Connect instances for multiple environments:Ĭonduktor displays the connectors on the main list in error (clearly in red). Topics: which topics does the connector listen from or write into.Type: quickly understand what this connector does.Instance / Name: instance is only displayed if you have multiple Kafka Connect instances configured, this is to distinguish between them.There is a lot of information when it comes to Connectors!
