Cassandra at scale
It’s one of the database platforms we offer to the development community in our organization. We have various selections when it comes to databases including DB2, SQL Server, Oracle, and hadoop for data warehousing. Cassandra becomes the choice when developers want to use a highly available NoSQL db.

Cassandra: A highly available and scalable database
We use Cassandra as the NoSQL database for our use cases. We stream a lot of API data into this database and rely on the availability it gives us. It has proven to be consistent, which we use to our advantage. Cassandra can distribute data across multiple machines in an app-transparent manner, thus helping us to expand it on demand.

Cassandra - a tunable NoSQL datastore
Cassandra is a NoSQL database which is used to store a large amount of data quickly. It has a very fast write speed, allowing a large volume of data storage within a small amount of time. It is tunable and can be used to store data. It is more suitable for storing flat data rather than relational data.

Pretty good software
Cassandra is used in my organization by my department to handle data that is not in a standard RDMBS format.

Cassandra, put into the real business context
We use Cassandra to build a fully functional POC (with the continuous production level volume of feeding data) for a shipment cloud concept for Fedex's EMEA region. This solution is composed of two parts, we use an IMDG product to keep the latest transaction of all shipments' latest "status" while we use Cassandra as our long-term transaction storage to keep all historical shipment status update events. On top of those InMemory and NoSQL storage, we built one unified RESTful based service, which depends on the user's query needs, either/and/or query the IMDG for the latest status of the shipment or query the Cassandra for the history of the shipment. Also, the Cassandra is used as the "backup" of the IMDG, in case the IMDG part is fully crashed (the worst scenario). Thanks to the time series way of persisting the data in Cassandra, we still can extract the "latest" status of a shipment from Cassandra's full transaction history with reasonable performance (slower than IMDG but much quicker than the traditional relational database).

Cassandra Usage and Needs
We are using Cassandra based on the requirements and data availability to the application (based on queries for search).

Cassandra as NoSQL fault tolerant database choice
Cassandra is an open-source NoSQL database solution offered by Apache. What's nice about Cassandra is its ability to host the data in multiple nodes in a ring, and changes made to a node in the ring will shard the update to the rest. For geographically dispersed architecture requiring local database storage, this can be a valuable asset which makes this NoSQL option stand above the rest.

Cassandra, a highly scalable NoSQL DB
We wanted to use Cassandra to load millions of metrics we collect daily from our user base. After we collected the data we also needed to perform calculations and run "sql" like queries. The only database that came to mind, and does all those things well, is Cassandra.

What makes Cassandra different!!!!
I had used Cassandra in my academic projects which were related to cloud computing. I used it for a few projects on Salesforce where multi tenancy features are implemented. In such scenarios Cassandra was one the best choices for NoSql. Although we have used RDMS, the performance while using Cassandra was better.
I have simulated a few real time running apps like Facebook and Uber where I have used RDMS and Cassandra, and checked the performance using Jmeter. It clearly shows that Cassandra boosts the performance over RDMS. One thing I find difficult in Cassandra is following the documents, which are not so understandable.

Cassandra, hands-on review, after 4 years of serious use
Cassandra is the only database used by Algorithmic Ads. We use it for both real-time transactions and analytics. The primary application accessing Cassandra is a light-weight Java application that provides a RESTful web services API for all our other applications. The API is a focal point for integration and includes both business logic and data. The same API is used both internally and by our customers. We rely on Cassandra for its amazing performance, linear scalability, and continuous availability.

Cassandra Rocks !!!
We used Cassandra to store personalization data of our customers so that we can have this information available through the cluster. The primary advantage of Cassandra is the cluster configuration so that there is not a single point of failure. The writes are faster when you want to write data into the storage. We used it for storing data in JSON format which is used to store anything in JSON format. The data was always up to date and there was less latency when we read from the system. I would highly recommend using Cassandra so as to make a system more scalable and process requests faster.

Cassandra - pretty good if you know what you are doing
Cassandra is being used as a time series store for sensor data and is used by several researchers within our department.
It serves as the storage layer in our home grown sensor analytics platforms that utilizes spark for the computation. We use it to store billions of samples of wearable sensor data that is collected in various studies and experiments.

Cassandra is used as a component of our HyperStore S3-compatible object storage system. Cassandra is installed on each node and provides the distributed system logic to determine how to store objects. The other components are primarily Java servers that we wrote that work in conjunction with Cassandra to provide a scalable, peer-to-peer, highly fault tolerant system.
