Paddy Power Selects DataStax Enterprise To Manage Time-Series Data For Online Gaming Application

This article is one in a series of quick-hit interviews with companies using Apache Cassandra and DataStax Enterprise for key parts of their business. For this interview, we spoke with John Turner who is a Software Development Manager at Paddy Power.

“We chose Cassandra because of its ability and proven track record in managing time-series data.”

John Turner
Software Development Manager, Paddy Power

DataStax: Tell us about Paddy Power.

John: I think the statement from our corporate website describes Paddy Power better than I ever could.

”Setting a Guinness World Record for the biggest ever strip poker tournament, sponsoring the World’s first Father Ted Festival, having a Tongan International Rugby player change his name by Deed Poll to Paddy Power for the duration of the 2007 Rugby World Cup……just a few reasons why Paddy Power has become a household name synonymous with fun and entertainment.

Formed back in 1988 Paddy Power rapidly became a shining light in the Irish and UK betting industry. Innovation has been the key to the success for the company who from day one sought to be different from the chasing pack. The vision was simple, position betting as entertainment; make betting with Paddy Power a fun experience that meant a lot more than simply winning or losing money.

This dogged refusal to conform and obsession with delivering an unparalleled customer experience ensures that Paddy Power holds a specials place in the minds of punters.”

DataStax: Can you give me an overview of your infrastructure? How do you power your business from a technology perspective?

John: We operate multiple data centers in Europe and in Australia. For regulatory reasons, our infrastructure is predominantly private and like the majority of today’s corporate data centers is heavily virtualized. As you can imagine, our compute requirements contain large peaks and troughs dictated by the timing of sporting events and we need to provision for those peaks.

DataStax: What were some of the business or technical problems that caused you to go down the NoSQL path, and in particular, what drove you toward Apache Cassandra and Datastax Enterprise?

John: Traditionally and to date, we have used a number of different relational database technologies with all their features and limitations that they present. As we challenged ourselves to provide greater levels of performance, scalability and resilience, we started looking at some of the NoSQL solutions that were. We spent quite a bit of time evaluating a number of those solutions, and we really focused on ease of cross datacenter replication and scalability both in terms of performance and cost.

That led us to look at peer-to-peer based NoSQL solutions that had lower operational overheads than solutions based on other distribution topologies. We were looking for solutions that supported auto-sharding so that we didn’t have to manually distribute data across shards as the characteristics of our data changed. That discounted some of the solutions in the marketplace.

Early in our evaluation period, there was some interest in a number of the technologies that provide key based sharding and richer secondary index capabilities such as those found in Mongo. They options were discounted basically because of the cost of scaling, the operational overhead of scaling, and the lack of a compelling requirement for secondary indexes and ad-hoc querying.

DataStax: Let’s talk about some of the systems that you power today with Datastax Enterprise. Were they previously handled with relational databases?

John: We are a heavy user of Informix and some of our systems were using Informix exclusively as a persistent source. There still are features within those applications that continue to require strongly relational data features. Those that don’t require relational features have migrated onto Cassandra. One of the other key drivers for migrating those features was to move away from the explicit schemas. The benefit of moving away from explicit schemas is that it gives us the ability to perform upgrades to our applications without requiring down time using versioned reader and writer patterns.

DataStax: What caused you to Datastax Enterprise over just open-source Cassandra?

John: Partly it’s the warm fuzzy feeling of having a vendor that’s standing behind you. We had limited experience with NoSQL, and Cassandra specifically, so having a vendor with proven experience providing enterprise-level software and support to its customers was very attractive to us. The availability of things like support, training, OpsCenter and the value of additional features in Datastax Enterprise were compelling to us as well.

DataStax: How do your customers interact with Datastax Enterprise? What are some of the applications that you’re using our software for?

John: The applications that provide real-time product and pricing to our customers are leveraging Cassandra for its ability to persist and store that information in real-time. We chose Cassandra because of its ability and proven track record in managing time-series data. Our product and pricing is in effect data that’s time-series, a bit like a financial market, stock, and stock ticker. We have an eight-node cluster, which is split evenly across two data centers, and that provides us the capabilities to provide active-active service across both data centers.

DataStax: You mentioned OpsCenter as being one of the reasons why you are using Datastax Enterprise. How are you using it, and what has your experience been? Did any other features attract you?

John: I’ll give you a little bit of insight into the sorts of questions that Datastax was able to answer that we weren’t able to get from the open-source community. Being an enterprise customer, things like security and operability really weigh heavily on our decision to partner with a vendor. The security features that come with Datastax Enterprise allow us to satisfy the internal security requirements that we would typically have for any of the software that we adopt.

From an operations perspective, OpsCenter gives us the capabilities that you would expect of any enterprise database solution, like the ability to perform backup and retrieval, the ability to apply security restrictions, to monitor in real-time the database, etc. Those are the main drivers.

DataStax: From a business perspective, cost wise, you mentioned that this solution has replaced some of the Informix that you were using. Have you realized any cost benefits from moving to this?

John: The infrastructure that we moved from still exists and it’s still used for features that aren’t really suitable for using a distributed database solution for. There’s certainly no cost savings in respect to that, but given the fact that it is an implicit schema, it allows us to reduce the number of people that are involved in evolving that database schema.

Traditionally, it would have involved application development, operations, and our DBA team to collaborate around database changes and changes to schema. Whereas now, it only requires the development team to deliver via an automated, continuous delivery process, which effectively means that they’re able to roll out changes to the implicit schema a lot quicker than they would have been able to in the past.

DataStax: If somebody who is brand new to NoSQL or Cassandra came to you and was just asking for some advice, what would you tell them? What advice would you give someone who is just starting with the technology?

John: You want to select a use case within your organization that’s low-risk and where the NoSQL solution has proven value in other. This way you’re minimizing your risk and you’re guaranteeing your outcome to some extent because you’re taking a new path from a technology perspective, but it’s a path that’s been trodden by other organizations.

Specifically for Cassandra and Datastax, the ability to process time-series data is something that lots of companies have done in the past, not something that we were very aware of, and that was one of the reasons why we chose this as the first use case for Cassandra.
