restserver | RESTful resource/url mapping | REST library

The way Flink works internally is that the Dispatcher creates for every submitted job a dedicated JobMaster component. This component needs a leader election and for this purpose it creates a k8s-ha-app1--jobmanager config map. This is the reason why you see multiple xyz-jobmanager ConfigMaps being created.

The reason why these ConfigMaps are not cleaned up is that this currently happens only when the whole cluster is shut down. This is a limitation and the Flink community has created FLINK-20695 in order to fix it. The idea is that the JobMaster related ConfigMaps can be deleted after the job has reached a terminal state.

A bit related is another limitation which hampers the proper clean up in case of a session cluster. If the cluster is shut down with a SIGTERM signal then it is currently not guaranteed that all resources are cleaned up. See FLINK-21008 for more information.

If you have control over the RestServer source file you can add an empty companion class.

Hello from the LoopBack team 👋

In order to allow openapi-to-graphql understand relations, the OpenAPI schema produced by a LoopBack application must describe Links between entities.

LoopBack 4 does not provide such metadata out of the box. We have been discussing this use case in GitHub issue loopback-next#2153, unfortunately we haven't found a clear solution yet.

What you can try: In your controllers, enhance your response specifications with a links section pointing to relevant API endpoints for accessing the related models.

it seems to me that the database named test either does not exist or is not visible by the user pg.

Resolved the error by starting the connect-standalone using source and sink properties together.

Here's the error:

Missing required configuration "confluent.topic.bootstrap.servers" which has no default value.

The problem is that you've taken the config for the HDFS Sink connector, and changed the connector for a different one (HDFS 3 Sink), and this one has different configuration requirements.

You can follow the quickstart for the HDFS 3 sink connector, or fix your existing configuration by adding

Finally, I added the "Authorize" button and send the api_key in the header, with this configuration:

Yes, as Marc suggested: add another DSServerClass component to the ServerContainerunit form. Connect that to a second servermethodsunit. The wizard will allow you to create one using File->New->Other->DataSnap->ServerModule.

Both DSServerClass components on the ServerContainerunit share the 1 DSServer via their Server properties. And rename your servermethods' TDSServerMethods instances. 1 as clients and 2 as suppliers. clients will have the getInvoices method, and suppliers will have the getorders method.

Yes, NoSuchMethodError typically indicates a version incompatibility between libraries.

The link you posted is to javadoc for kafka 0.10.2. The method hasn't changed in 1.0 but indeed in the upcoming 1.1 it only takes 2 Strings: https://kafka.apache.org/11/javadoc/org/apache/kafka/streams/StreamsConfig.html#getConsumerConfigs(java.lang.String,%20java.lang.String) . That suggests the version of KSQL you're using (4.1.0-SNAPSHOT) depends on version 1.1 of kafka streams, which is currently in the release candidate phase and I believe and should be out soon:

As per that email you can find the latest (1.1.0-rc2) artifacts in the apache staging repo: https://repository.apache.org/content/groups/staging/
