Can achieve continuous data without a single downtime because of node to node ring architecture

Pros and Cons

  • "Can achieve continuous data without a single downtime because of node to node ring architecture."
  • "I am getting much better performance than relational databases."
  • "Maybe they can improve their performance in data fetching from a high volume of data sets."

What is our primary use case?

I designed a product catalog data model in Cassandra according to their features and properties, loading millions of data and performing the required queries over it. 

Now, I am getting much better performance than relational databases.

What is most valuable?

Here are some features which have been really helpful in my organisation:

  • High Avaialability
  • No downtime
  • Better performance
  • Greater scalability.

HA is one of the great features of Cassandra with no downtime, e.g., you can achieve continuous data without a single downtime because of node to node ring architecture.

What needs improvement?

Maybe they can improve their performance in data fetching from a high volume of data sets. 

For how long have I used the solution?

One to three years.

Which other solutions did I evaluate?

I had to compare Cassandra with MongoDB. MongoDB is much better in data fetching than Cassandra.

Replication uses peer-to-peer protocol.

What is most valuable?

  • Simple ring architecture
  • Replication using peer-to-peer protocol rather than leader selection
  • Linear scalability (99%)
  • Configurable consistency

How has it helped my organization?

Ability to achieve write speeds 10k tps: Compared to existing, it is 300% percent higher.

What needs improvement?

Row-level locking is not available; might be very helpful in update use cases.

For how long have I used the solution?

for the past 2 years

What was my experience with deployment of the solution?

older version of Cassandra 2.x having problem while restarting the nodes to the ring. New version from Cassandra 3.5.x onwards this issue got resolved. We are free to stop and start any nodes without any issues.

What do I think about the stability of the solution?

no

What do I think about the scalability of the solution?

no

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

The earlier solution used Couchbase, which has leader selection. At times, when leader selection takes time, then we would lose the transactions. This got resolved with the peer-to-peer architecture solution in Cassandra.

How was the initial setup?

Initial setup is straightforward. If you want to do mass cluster setup then centralized tool will be of great help.

What about the implementation team?

in house implementation

Some of the valuable features include automated replication, linear scalability, and automated region fail-over

What is most valuable?

I really appreciate the high availability, automated replication, linear scalability, and automated region fail-over.

How has it helped my organization?

We've used Apache Cassandra for solutions that we sell to our customers. It's used as our cloud based backend store as a temporary cache and for storing data that streams through our data pipe. It's an excellent high speed store.

What needs improvement?

Out-of-the-box monitoring, troubleshooting, and maintenance are involved. There are several utilities/interfaces available for use, but one would have to educate himself and learn the intricacies of managing a Cassandra cluster.

For example, we recently hired a consulting firm to make recommendations on how to approach maintenance and the health of the cluster and we're learning from that experience.

For how long have I used the solution?

I have used this product for approximately two years.

What do I think about the stability of the solution?

We have had stability issues including out of memory issues and crashes with earlier versions of the product.

What do I think about the scalability of the solution?

We’ve not really had scalability issues, but scalability is solved by advanced tuning or adding nodes.

How are customer service and technical support?

We use the open source version, so support is pretty much on our group of developers and public forums/user groups. For example, I'm a member of the Cassandra user list mail group.

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

This is a new cloud based enterprise product, so there weren't previous solutions.

How was the initial setup?

The setup is not terribly complex, but a learning process was involved.

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

We use the open source version, so it's free. Costing needs to take into account home grown maintenance and support, as that can get involved.

Which other solutions did I evaluate?

We looked at Hadoop, Spark, Spark Streaming, and MongoDB.

What other advice do I have?

If you plan to use the open source version, make sure you hire a Cassandra expert or train yourself in the internals of Cassandra.

We use it as the storage facility for a very-high-throughput application.

What is most valuable?

  • Log-structured storage
  • CQL (Cassandra Structure Language)
  • Ease of installation
  • The node setup

How has it helped my organization?

This product is used as the storage facility for a very-high-throughput application, where a lot of NoSQL data is being captured and it needs to be processed.

What needs improvement?

The clustering needs to be better; it is getting there.

For how long have I used the solution?

I have used it for four years.

What do I think about the stability of the solution?

Cassandra is stable thus far; the problems that I have encountered were with CQL and the JSON support in CQL.

What do I think about the scalability of the solution?

The scalability is good, as long as you understand how to set up the nodes.

How are customer service and technical support?

I did not have any interactions with technical support, because I was able to find answers to my questions online as I did my searches.

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

The other solutions that I have used have been the SQL engines but for this project, Cassandra was determined to be the better solution.

How was the initial setup?

Setup was very straightforward.

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

Pricing and licensing depends on what you are doing: If you are using it for major production work, I recommend that you purchase the level of support that you would need.

Which other solutions did I evaluate?

This was the only product that was evaluated.

What other advice do I have?

Learn how many nodes you are going to need and set up the right level of replication.
