With this solution, we've reduced load on the OLTP systems.

What is most valuable?

The most valuable feature of Greenplum is the Massively Parallel Processing (MPP).

How has it helped my organization?

With this solution, we've reduced load on the OLTP systems.

What needs improvement?

The fact GreenPlum is using an older version of Postgres means developers coming from other products will find many missing features in PostgreSQL, features which you would assume are standard.

Greenplum is based on Postgres 8.2.15 which was released in 2009. While the SQL syntax and functionality has continued to evolve in other platforms in the ensuing years it appears to have stagnated in Greenplum.

What was my experience with deployment of the solution?

We haven't had any issues with deployment.

Flexible with good performance, but there are some security concerns
Pros and Cons
  • "It is easy to use. The addition of more queues and more services can be managed very easily."
  • "There are some security concerns that have been raised with this product."

What is our primary use case?

The use case involves the transferring of messages between services. It includes asynchronous messaging and I also need messages flowing to multiple microservices. In this case, it's basically a fan-out mechanism.

What is most valuable?

RabbitMQ is configurable and quite flexible.

The performance is fast and reliable.

It is easy to use. The addition of more queues and more services can be managed very easily.

What needs improvement?

There are some security concerns that have been raised with this product.

The configuration works with a config file, where all of the controls, including that of the administrator and user access, are stored there. The security isn't very stringent or very elaborate.

What do I think about the stability of the solution?

RabbitMQ is a stable solution.

What do I think about the scalability of the solution?

This is a scalable product. There are six or seven services that are connected and using it.

How are customer service and support?

I have not been involved with anything that necessitated contacting the support team.

Which solution did I use previously and why did I switch?

Previously, we were using MSMQ, which is the Microsoft Message Queuing service. However, with the new version of .NET 4, support for MSMQ was no longer available. We could no longer get the libraries. As a result, we had to switch to a different queue mechanism. 

I have also used Azure Queue.

How was the initial setup?

The initial deployment was quite easy. It took less than half an hour to get it up and running.

What about the implementation team?

I deployed it myself.

What's my experience with pricing, setup cost, and licensing?

The pricing for RabbitMQ is reasonable. It is worth the cost.

Which other solutions did I evaluate?

We researched ZeroMQ, RabbitMQ, and Kafka. We found that Kafka was a bit of an overkill because our requirements were quite simple. RabbitMQ was pretty easy to set up, which is why we chose it.

What other advice do I have?

My advice for anybody who is implementing this product is to establish your users and exchanges properly.

In general, I'm quite comfortable with RabbitMQ. It satisfies my requirements and the main complaint I have is about the security.

I would rate this solution a seven out of ten.

Which deployment model are you using for this solution?

On-premises

Helps to remove a lot of the complexities and create a loosely coupled codebase
Pros and Cons
  • "RabbitMQ will help to remove a lot of the complexities and create a loosely coupled codebase."
  • "I like the high throughput of 20K messages/sec, and that it supports multiple protocols."
  • "The next release should include some of the flexibility and features that Kafka offers."

What is our primary use case?

I am still comparing RabbitMQ and Kafka, but based upon the information I have gathered RabbitMQ is an awesome tool.

How has it helped my organization?

RabbitMQ will help to remove a lot of the complexities and create a loosely coupled codebase.

What is most valuable?

I like the high throughput of 20K messages/sec, and that it supports multiple protocols. The flexible routing is great as well.

What needs improvement?

The next release should include some of the flexibility and features that Kafka offers.

For how long have I used the solution?

Still implementing.

Which solution did I use previously and why did I switch?

I have used IBM MQ software, but it was not applicable to this application.

Which other solutions did I evaluate?

I have evaluated and researched Axon, RabbitMQ, Kafka, and IBM MQ.

Hi,

I am a real user too and I would say that it depends really on the context. You can consider two generation of brokers, old ones are pure brokers (RabbitMQ, ActiveMQ, ZeroMQ etc.) and new ones are stream oriented (Kafka, Artemis, etc.). The performance difference is huge, around 4000 msg/s for old brokers, around 60,000 msg/s for stream based.

we used RabbitMQ for years and we are moving right now for many reasons:
- RabbitMQ is one of the leading implementation of the AMQP protocol. Therefore, it implements a broker architecture, meaning that messages are queued on a central node before being sent to clients. This approach makes RabbitMQ very easy to use and deploy, because advanced scenarios like routing, load balancing or persistent message queuing are supported in just a few lines of code. However, it also makes it less scalable and “slower” because the central node adds latency and message envelopes are quite big.
- Nevertheless, Using standard AMQP 0.9.1, the only way to guarantee that a message isn't lost is by using transactions -- make the channel transactional, publish the message, commit. In this case, transactions are unnecessarily heavyweight and decrease throughput by a factor of 250. To remedy this, you need to implement confirmation mechanism that challenge a lot the easiness of implementation
- Replication on RabbitMQ 3.6 (the last version supporting AMQP 0.9,1) makes RabbitMQ having deadlocks between nodes and created a lot of issues in production in our systems
- Last, Erlang is a black box and many times RabbitMQ crashes with Erlang errors that were a shame to make us able to diagnose quickly and efficiently.

So my recommendation, don't use RabbitMQ on a transactional path, it remains good for back-office messages as long as you can implement your own transactions in an optimistic way (with retry and message duplication detection on application side)

In my context, we are moving to Kafka that shows performance, scalability and stability.

​Installation is very simple, make sure to set the configuration values based on the requirement.​

What is most valuable?

We can integrate the Hadoop with DCA V2. This will be huge development in the big data technologies.

How has it helped my organization?

It increased the read/write process because of it MPP architecture.

What needs improvement?

EMC already developed DCA V3, But if the hardware is little stable, I prefer DCA V2.

For how long have I used the solution?

I am from a support background, and have used this on multiple accounts, for the last four years.

What was my experience with deployment of the solution?

There have been no issues with the deployment.

What do I think about the stability of the solution?

Hardware failure is a concern.

What do I think about the scalability of the solution?

We have had no issues scaling it for our needs.

How are customer service and technical support?

Technical support is excellent.

Which solution did I use previously and why did I switch?

I know many customers are migrating from Oracle to Greenplum due to its faster processing.

How was the initial setup?

It is straightforward,open source system.

What about the implementation team?

Better chose EMC to perform the implementation. More over, it is not complex and we can do it easily in our environment with a little knowledge.

What's my experience with pricing, setup cost, and licensing?

Greenplum is an opensource system, but they do charge for support.

What other advice do I have?

Installation is very simple, make sure to set the configuration values based on the requirement.

Easy installation, excellent price point, with room for ongoing scalability
Pros and Cons
  • "The most valuable feature for me is that it is open source. The licensing costs are really low and they are transparent."
  • "I would like to see the performance of the administration portal improved and additional messaging protocols."

What is our primary use case?

Our primary use case is as a messaging broker between enterprise applications. It makes for reliable and secure communication.

What is most valuable?

The most valuable feature for me is that it is open source. The licensing costs are really low and they are transparent. You know how much you are going to pay if you want the commercial version. If you want the open-source version, you do not have to pay anything and that is just as reliable as the commercial one.

What needs improvement?

I would like to see the performance of the administration portal improved and additional messaging protocols.

For how long have I used the solution?

I have been working with VMware RabbitMQ for the past eight years.

What do I think about the stability of the solution?

It is highly stable, reliable, and persistent.

What do I think about the scalability of the solution?

VMware RabbitMQ is definitely scalable.

How are customer service and support?

Technical support is excellent.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup was very easy and takes about five minutes to install.

What's my experience with pricing, setup cost, and licensing?

If you want to pay for the licensing it costs eight hundred dollars per CPU core annually with the support.

What other advice do I have?

I would give the following advice prepare a demo, with the vendor and check if it really applies to their needs. I would rate VMware RabbitMQ a nine out of ten.

Which deployment model are you using for this solution?

On-premises

Offers a publisher and consumer ACK and does queue mirroring.

What is most valuable?

  • The publisher and consumer ACK
  • High availability
  • Queue mirroring
  • Exchanges and topics
  • Supported programming languages with well-tested libraries

How has it helped my organization?

It provides us with a much better scale. We have never lost a single message with RabbitMQ.

The shared RabbitMQ Cluster has improved stability and maintainability of each application. We only have one message bus now.

What needs improvement?

I want it to reorder messages in a queue, if possible. If you could reorder messages in a queue directly, then you would not need a sequencer to reorder messages outside of RabbitMQ.

For how long have I used the solution?

I have used this solution for seven years.

What do I think about the stability of the solution?

There were no stability issues.

What do I think about the scalability of the solution?

There were no scalability issues.

How are customer service and technical support?

We haven’t needed to use any support yet.

Which solution did I use previously and why did I switch?

Initially, we were using the BizTalk and Redis solutions. The reason why we switched over was because we were looking for better support in Celery task management and other programming languages. We were looking for a much more stable and secure solution.

How was the initial setup?

It is very simple to set up for basic usage. Clustering is a bit more complex, but it is also easy to do.

What's my experience with pricing, setup cost, and licensing?

The RabbitMQ open source version works fine for almost all the use cases that I came across.

Which other solutions did I evaluate?

We looked at the Redis solution, but it was not a good fit for our needs.

What other advice do I have?

Read the documentation and follow best practices. Make sure Erlang is up to date!
