            The Go code you provided will not impact the way how the Time instance will be serialized as you are parsing it back into Time after serializing it to a string.

            If you have control over how your date fields are serialized, you can apply the following format that should be aligned with what you provided to Jackson's ObjectMapper:

            Why ActiveMQ Artemis auto delete address if all listeners are destroyed?
            Asked 2021-Jun-02 at 16:28

            We are develop a micro-service system that use ActiveMQ Artemis as the communication method between service. Since the requirement ask to be able to stop the listeners at runtime, we can not use @JmsListener provide by spring-artemis. After digging the internet and finding out that spring use MessageListenerContainer behind the scence, we come up with the idea of maintain a list of MessageListenerContainer our self.

            By default the broker will auto-create addresses and queues as required when a message is sent or a consumer is created by the core JMS client. These resources will also be auto-deleted by default when they're no longer needed (i.e. when a queue has no consumers and messages or when an address no longer has any queues bound to it). This is controlled by these settings in broker.xml which are discussed in the documentation:

            • auto-create-queues
            • auto-delete-queues
            • auto-create-addresses
            • auto-delete-addresses

            To be clear, auto-deletion should not cause any message loss by default as queues should only be deleted when they have 0 consumers and 0 messages. However, you can always set auto-deletion to false to be 100% safe.

            Queues representing durable JMS topic subscriptions won't be deleted as they are meant to stay and gather messages while the consumer is offline. In other words, a durable topic subscription will remain if the client using the subscription is shutdown without first explicitly removing the subscription. That's the whole point of durable subscriptions - they are durable. Any client can use a durable topic subscription if it connects with the same client ID and uses the same subscription name. However, unless the durable subscription is a "shared" durable subscription then only one client at a time can be connected to it. Shared durable topic subscriptions were added in JMS 2.0.

            Godog Undefined Steps when Steps are present
            Asked 2021-May-25 at 07:43

            I've been implementing feature file tests for a microservice in Golang using Godog.

            When reading resource of id "ID1"_____(blank space)

            The regex pattern therefore wasn't able to map the step definitions to these lines for some reason.

            First, if you use reactor you shouldnt call blocking apis, as you did it in the save method. When you use webflux, you have a small number of threads and if you block those threads your application performance will be very poor. I suggest using reactive database driver instead.

            1, You shouldnt use plane object in the controller, because you have to block the thread to get the object itself. In reactor, you mustnt call blocking operation. Also suggest to use blockhound if you are not sure about what is blocking. It will throw an exception during tests if blocking methods are called.

            2, In reactive stream, you have to use the reactive operations, like map, flatmap, etc.. to do operations on your objects.

            For example, suppose you want to go through a list of objects, load some data from web to each and save those into the database (note that here I'm going to use mock db and webservice, but you can change those into real services and the essence of the example is the processor. Also I use Kotlin here, which is similar to Java)

            I managed to fix the problem with the help of Allard (see comments on question). The fix was to also persist the token after it has been claimed in the fetch() method. We also started making use of the replace() method supplied by the Couchbase SDK instead of the upsert() method, to better harness the CAS (Compare-and-Swap) optimistic concurency:

            When to NOT use a message broker such as RabbitMQ in a micro-services architecture?
            Asked 2021-Apr-09 at 12:19

            I am new to the concept of messaging brokers such as RabbitMQ and wanted to learn some best practices.

            RabbitMQ seems to be a great way to facilitate asynchronous communication between micro-services, however, I have a beginners question that I could not find an answer to anywhere else.

            When would one NOT use a message broker such as RabbitMQ in a micro-services architecture?

            As an example:

            Let's say I have two services. Service A and Service B (auth service)

            The client makes a request to service A which in turn must communicate with service B (auth service) to authenticate the user and authorize the request. (using Basic Auth)

            Well actually what you are describing is mostly close to the HTTP.

            HTTP is synchronous which means that you have to wait for a response. The solution to this issue is AMQP as you mention. With AMQP you don't necessarily need to wait(you can configure it).

            Its not necessarily a bad idea but what most microservices depend on is something called eventual consistency. As this will be a quite long answer with a lot of ifs I would suggest taking a look into Microservices Architecture

            For example here is the part about the http vs amqp since its mostly a question about sychronous vs asychronous communication It goes into great detail about different approaches of microservices design listing pros and cons for your specific question and others.

            For example in your case the Auth would happen at the API gateway as its not considered best practice to leave the microservices open for all the client applications.

            Is it possible to create custom fields in a Kibana dashboard?
            Asked 2021-Mar-31 at 04:40

            I am using a Java micro-service architecture in my application and generating separate log files for each micro-service.

            I am using ELK stack approach to visualize the logs in Kibana, but the problem is whatever the fields that I'm getting from Elastic Search that are related to server logs fields. some example fields are @timestamp,@version,@path,@version.keyword,@host.

            i want to customize this fields by adding some fields like customerId,txn-Id,mobile no so that we can analyze the data easily.

            I'm using org.apache.logging.log4j2 to write the logs. Can I set above fields (customerId,txn-Id,mobile) to log files? And then Elastic will store these fields with the above default fields and then these custom fields should available in a Kibana dashboard. Is this possible?

            It's definitely possible to do that. I've not done it with the log4j2 stack (I have with slf4j/logback), but the basic approach is:

            • set those fields in the Mapped Diagnostic Context (I'm fairly sure log4j2 supports that)
            • use a log appender which logs to logstash-structured JSON
            • configure filebeat to ship the JSON logs
            • if filebeat is shipping to logstash, you'll need to configure logstash to pass those preformatted JSON logs directly to elasticsearch
