QUESTION
I am using ActiveMQ Artemis 2.19.1. I created producer and consumer apps using Spring Boot. I need multiple instances of the consumer to receive all the messages (multicast). I configured a Last Value Queue like this (broker.xml
):
ANSWER
Answered 2022-Mar-16 at 19:17It sounds to me like everything is working as designed. I believe your expectations are being thwarted because you're using pub/sub (i.e. JMS topics).
Let me provide a bit of background. When a JMS client creates a subscription on a topic the broker responds by creating a multicast queue on the address with the same name. The queue is named according to the kind of subscription it is. If it is a non-durable subscription then the queue is named with a UUID. If it is a durable subscription then the queue is named according to the subscription name provided by the client and the client ID (if available). When a message is sent to the address it is put in all the multicast queues bound to that address.
Therefore, when a new non-durable subscription is created a new queue for that subscription is also created which means that the subscriber will receive none of the messages sent to the topic prior to the creation of the subscription. This is the expected behavior for JMS topics (i.e. normal pub/sub semantics). Also, since the queue for a non-durable subscription is only available while the subscriber is connected that means there's no way to enforce LVQ semantics since any message which arrives in the queue will be immediately dispatched to the consumer. In short, LVQ with JMS topics doesn't make a lot of sense.
The behavior changes when you use a JMS queue because the queue is always there to receive messages. Consumers can come and go as they please while the broker enforces LVQ semantics.
One possible solution would be to create a special "initialization" queue where consumers could initially connect to get the latest information and after that they could subscribe to the JMS topic to get the pub/sub semantics you need. You could use a divert to make this transparent for the applications sending the messages so they can continue to just send to the JMS topic. Here's sample configuration:
QUESTION
Using Apache ActiveMQ Artemis, is it preferred to have one topic with String
properties used to differentiate them or many topics? e.g., should publishers do this:
ANSWER
Answered 2022-Mar-22 at 17:29Generally speaking, there's nothing intrinsic about ActiveMQ Artemis that would necessarily push you one way or the other.
However, your use-case is rather unique with the retroactive-address + LVQ configuration. My concern here with using a single address is that if there really are 100,000 symbols and the last value for each symbol should be retained then the ring-queue backing the retroactive address will potentially need to be 100,000 messages deep which means that every time a subscription queue is created on that address then the broker will have to process all those messages. I expect that would be a significant burden on the broker.
Therefore, at this point I'd say that an address for each symbol is likely the best. Then the retroactive-message-count
can be 1
.
Ultimately my best advice would be to actually test these two different configurations with a production-like load and then choose the one that best fits your use-case in terms of performance, manageability, etc. The devil is always in the details with this sort of thing. There are too many moving parts and unspoken requirements to provide an authoritative recommendation in a context like this.

Answered 2021-Nov-03 at 16:08You're (re-)adding the same object to the list, over and over.
You need to create a new object every time your loop runs, but you can still "template" the objects - just use a hashtable/dictionary instead of a custom object:
QUESTION
I have a cluster of Artemis in Kubernetes with 3 group of master/slave:
...ANSWER
Answered 2021-Jun-02 at 01:56I've taken your simplified configured with just 2 nodes using a non-wildcard queue with redistribution-delay
of 0
, and I reproduced the behavior you're seeing on my local machine (i.e. without Kubernetes). I believe I see why the behavior is such, but in order to understand the current behavior you first must understand how redistribution works in the first place.
In a cluster every time a consumer is created the node on which the consumer is created notifies every other node in the cluster about the consumer. If other nodes in the cluster have messages in their corresponding queue but don't have any consumers then those other nodes redistribute their messages to the node with the consumer (assuming the message-load-balancing
is ON_DEMAND
and the redistribution-delay
is >= 0
).
In your case however, the node with the messages is actually down when the consumer is created on the other node so it never actually receives the notification about the consumer. Therefore, once that node restarts it doesn't know about the other consumer and does not redistribute its messages.
I see you've opened ARTEMIS-3321 to enhance the broker to deal with this situation. However, that will take time to develop and release (assuming the change is approved). My recommendation to you in the mean-time would be to configure your client reconnection which is discussed in the documentation, e.g.:
QUESTION
Summary:
I want to make NGINX (not NGINX Plus) re-resolve the IP address from the DNS name by using a variable in proxy_pass
(as suggested in this official Nginx article in the section "Setting the Domain Name in a Variable"). But when I do that it won't set/forward the correct Content-Type
header, but always use text/html
, for .css
, .js
etc. files.
My setup:
I have a frontend and a backend service running in separate Docker containers (to be deployed to OpenShift in production). There's also a third container that runs nginx:latest
(v1.19.9 as of today) and acts as a reverse proxy, forwarding calls made to /my-app
to the frontend and /my-app/api
to the backend container. The NGINX reverse proxy has set them up as upstream servers using their DNS names.
All three containers run within the same custom Docker network, so resolving in itself works fine - but only, when NGINX is (re-)started.
The problem:
When the frontend or backend container gets restarted it may get a new IP address. Since NGINX caches IP addresses I'm getting a 502
when I make calls to them. I want NGINX to re-resolve the IP address more frequently, like NGINX Plus does. This is how the problem with the Content-Type
came up, when I tried to have NGINX re-resolve DNS names.
The configuration:
Here's my NGINX configuration (simplified to the relevant stuff only):
ANSWER
Answered 2021-May-24 at 16:12This isn't a problem with Content-Type
. You are using proxy_pass
incorrectly. As you have already noted:
When using variables in proxy_pass, if URI is specified, it is passed to the server as is, replacing the original request URI.
You currently have the following working configuration, but you want to replace it with a variable to force DNS resolution:

Answered 2021-May-12 at 19:58Okay, so I am pretty sure that this was an impossible task I was trying to complete.
By nature pytesseract.Output.DATAFRAME

Instead, I created a class that could hold the original image and the ocr output dataframe at the same time. Here is what the instance initialization looks like:
QUESTION
I'm creating a tile-based game in Unity (C#) with a hexagonal grid. I am making hills and mountains in my game, and to optimize, I only activate the top layer of tiles and leave the rest of them inactive. I render each tile with a noise-based height map (please note the colors on the grid itself such as brown, green, and grey do not correspond to height).
However, I encounter issues when the hills become high and a vertical gap between one tile and the next reveals a hole in the map due to height disparities.
To fix this, I am making a retroactive function which cycles through each pixel on the noise map and if it detects a disparity between one pixel and another which borders it, then it will activate the tile below the higher tile in the disparity. The blue tiles below represent the tiles that it detected as being in a disparity, and the red ones are the tiles activated as a result of their higher counterparts being detected as such.
Most the time, however, the disparities are not recognized in the right positions. You can see in the image above that the brown tile which should be considered as having a disparity (since it's leaving a gap) has a gaping hole and no red tile beneath it, while others which have no gaps are considered as having disparities and are thus blue. Here is a representation of how there's little correlation between the height map and the disparities detected:
You can see above that the white on the height map, representing high areas, does not correspond with the blue on the grid, which should correspond with disparities (and thus mainly correspond with where the white and the black converge on the noise map, outlining the location between high and low areas).
Here is my code to detect disparities:
