The MPP element is crucial, so far as it allows us to query millions of rows at a time, at speed.

What is most valuable?

The MPP element is crucial, so far as it allows us to query millions of rows at a time, at speed.

How has it helped my organization?

The previous data warehouse was built in Oracle. One of the things which has improved in GreenPlum is that we can query millions of rows at speed, without creating lags. We’ve also built far more views; slowly changing dimensions can instantaneously update without creating the issue of having to rebuild tables to reflect new hierarchies, for example.

What needs improvement?

We found some issues with larger tables that have daily data appended, where after a while this seems to create lag in the query speed. This might just have to do with local knowledge rather than the product itself.

We have a table which is currently contains 27.6m rows and has a daily delta added to it of roughly 16.5k rows per day. While this isn’t particularly large, we have noticed the table begins to perform poorly when queried, in spite of having set up a VACUUM process to be performed weekly. It may be that the VACUUM process needs to be performed more frequently (like daily), but we’ve not yet found the optimal way of maintaining this particular table.

It’s worth saying that this is one table out of over 400 perfectly well performant tables and views in the same database. Hope that helps,

For how long have I used the solution?

I have used for approximately 30 months.

Regarding the performance of few large tables, just a suggestion you can also try implementing the partitioning. By doing partitioning you can leverage the "swap partiton" while doing an insert and select the data for reporting based on your partitioning key.
Hope this helps

It provides file loaders to reduce dependency on Informatica.

Valuable Features

  • Distributed data for performance
  • File loaders to reduce dependency on Informatica

Improvements to My Organization

Batch processing times have dramatically decreased from over 12 hours to under three hours. Much of this is converting off of Informatica and using distributed processing. Reporting performance also improved greatly.

Room for Improvement

Since we are upgrading to a new version at this time, it’s hard to say. But we seem to be replacing a disk on the appliance every week.

Use of Solution

I've used it for six years.

Deployment Issues

There's no issues, although we are currently in the middle of an upgrade to v4.3.5.

Stability Issues

It seems like we are replacing a disk on the appliance every week. Not a noticeable issue for users and batch processing is not adversely impacted.

Customer Service and Technical Support

Very good. Response times are good for service calls.

Initial Setup

I believe the set-up was straightforward. I don’t remember any issues.

Implementation Team

We used a vendor team. My advice is that the planning is critical. When converting processing jobs, convert them to PostgreSQL for better performance. Yes they could work as written previously, but you benefit using the features of the product immediately if you adjust the processing to match appliance. Use the bulk processing to your advantage.

Other Solutions Considered

We evaluated other solutions. Not sure of the reasons why this product was chosen.

Other Advice

It’s a good product. We moved from Oracle and I don’t want to go back.

Top 10
Fairly secured, quite robust, and stable but their support is lacking
Pros and Cons
  • "The security is great."
  • "Their implementation is quite tricky. It's not that easy to implement RabbitMQ as a cluster."

What is most valuable?

The security is great. The interface is nothing special. The support hasn't been that great. You need to go online yourself, to the developer community for support. But apart from that, I think it's fairly secured, quite robust, and stable so far.

What needs improvement?

Their implementation is quite tricky. It's not that easy to implement RabbitMQ as a cluster. It would be great if they could improve that. 

For how long have I used the solution?

I have been using RabbitMQ for three years. 

What do I think about the stability of the solution?

It's quite stable.

What do I think about the scalability of the solution?

It is very scalable. I have a team of 10 developers who are using it and I have some of our clients using it in our Cloud cluster. We have about 10 banks running on the platform now.

How are customer service and technical support?

I would rate their support as a five out of ten. It has room for major improvement. 

How was the initial setup?

The initial setup is quite straightforward. It can be done within a few hours. 

What other advice do I have?

I would recommend it, but I think there should be a proof of concept for the developer team to get their hands around it and have full control of it before they go into production.

I would rate RabbitMQ a seven out of ten. 

In the next release, I would like for them to improve the UI.

Which deployment model are you using for this solution?

The documentation needs to be improved. There's a learning curve on setting it up and there are issues arising from slower networks that they lack documentation on.

For how long have I used the solution?

We have been using the product for three years.

What do I think about the stability of the solution?

Stability issues experienced were only due to a slow network at the client.

What do I think about the scalability of the solution?

We did not encounter any scalability issues.

How are customer service and technical support?

I never used the technical support.

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

I am not aware of any previous solutions.

How was the initial setup?

We are a container shop and the only issues during setup were around proper clustering and configuring the application to use it.

Which other solutions did I evaluate?

We evaluated Apache Kafka also.

What other advice do I have?

I would advise potential customers to use something to wrap their interaction, like Spring for Java.

The loaders – their methods, insert, update and merge – were most valuable.

What is most valuable?

The Greenplum loaders – their methods, insert, update and merge – were most valuable. The external table feature within Greenplum was also very valuable in achieving performance and scalability

How has it helped my organization?

A lot of customers use Greenplum and for their ETL use cases they use Informatica PWX for Greenplum, which helps them achieve transfer of data from a number of data sources into Greenplum. We can help customers to load data effortlessly and quickly.

What needs improvement?

It would be best if Greenplum would support array writes through ODBC drivers . Currently through Data Direct Greenplum drivers we can have single row inserts into Greenplum only. It would help if array loading is supported.

For how long have I used the solution?

I have been using Greenplum loaders to load data into GreenPlum for three years.

What was my experience with deployment of the solution?

There were no issues in deploying it.

What do I think about the stability of the solution?

The external table feature helps to make this a stable solution.

What do I think about the scalability of the solution?

It scales to our and our customers needs as required.

How are customer service and technical support?

The ongoing response from their support on certain technical issues has been slow. It would help if we can have a faster turn-around here.

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

There was no other solution used previously.

How was the initial setup?

The installation and configuration is straightforward.

What about the implementation team?

We implemented through a in-house team . The overall solution will be useful and is not complex

What other advice do I have?

If the use case is going to be requiring a huge data transfer and big data analytics. This is a good product to use.
