Cassandra Use Cases and Deployment Scope
Comments: 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.
Undoubtedly performance is an important reason
We have not encountered a single point of failure
Scalability of Cassandra is good which is the most important for the companies where demand is scaling day by day.
Cassandra has a wide range of asynchronous jobs and background tasks that are not scheduled by the client, the execution can be eccentric.
Because Cassandra is a key-value store, doing things like SUM, MIN, MAX, AVG and other aggregations are incredibly resource intensive if even possible to accomplish.
I think querying options for retrieving data is very limited.

Pros: I like it scales very easily when we see increase it traffic
Cons: Cassandra does not support joins so it is difficult to use as complex OLTP system

Cassandra : Zenith of Open Source NoSQL
Comments: We have quite complex requirements of tracing Buses/Truck of African cities of Rwanda for real-time reporting of schedule, breakdown, Traffic management of City using Apache Cassandra. Our team chose Cassandra for quite few reason. Open Source, Fault Tolerance, High Availability, Scalability, and Reliability of software components. I am happy that our team has chosen the right software for delivering complex software Solutions for Our Connected Vehicle Platform. We used it for real-time transactions and analytics. PROs: Fault Tolerance, Availability, and Superb Performance. CONs: It's not good for managing your Application processing. Its NoSQL DB requires lot of different understanding and NoSQL comes with its own issue so it shifts from traditional thinking process of RDBMS. Cassandra required very big learning curve which adds to the cost but benefits out weight this learning cost.

It has been a pleasant and rewarding experience for the management of data in the cloud and totally
Comments: It was very useful to me when I had to develop an application that needed a relational database and a non relational database that was going to be in the cloud, it was very useful and easy to use, as well as it did not give me problems for its use.
Pros: It has been a pleasant and profitable experience for the handling of data in the cloud and totally free, the handling of the data oriented to column families, tolerant to failures, since it replicates the data automatically to multiple nodes; When a node fails it can be replaced without any period of inactivity. allows replicas to multiple data centers; data storage type column family. The latest version of CQL3 that made the instructions similar to SQL with what breaks with the mental shock at the time of programming. It really does an efficient handling of data in the cloud.
Cons: The fact of having the data stored column by column allows us to return the rows more quickly, but when inserting, updating or deleting a record, it must be done in more than one location; for this reason, this type of database is not recommended for OLTP-type, transaction-oriented and high-concurrency systems.

A promising and powerful NoSQL database.
Pros: It is great for the right workload; with heavy writes and eventual consistency, it is a leader in the NoSQL space. I recommend Datastax for support using and supporting it.
Cons: Maintaining a cluster and an ops center server (for backups and monitoring) can get quite pricey. The learning curve of maintaining a cluster is a bit long.

lightning fast key store
Comments: we needed to build a scalable object store with high write load (write is the main pattern of usage)
csql syntax is powerful
lightning fast read/writes
smart client to reduce hops to the correct node
easy to install
cluster management complexity
problematic node recovery

It was good, until we hit GC
Gabriel m. M.
Comments: We were able to offload tables from our MySQL to NoSQL.
Pros: It was the best NoSQL solution for our organization. decent performance and cross-Datacenter replication.
It's written in JAVA. GC was killing us. at some point we had a server on GC for 30 min every 15 min.
we had to add more and more servers to deal with the situation. DataStax's PHP driver was using the first server available as a 'Contact point' when it was on GC, the second server on the list was hit and sometimes caused to crash; as result - we had a domino effect and an entire cluster would have crashed. (that, btw, was fixed and now Contact point is random). There is a better alternative ***SCYLLADB****
Since we moved to Scylla - we were able to reduce the amount of servers by 75%.
Performance and stability is magnificent. client side hasn't changed - running with the same drivers.

good option from NoSql family database
Comments: Just very good NoSql database in scenarios where you have to deal with large and hig velocity data in real time.
Pros: Cassandra is good choice from NoSql database when you need to store data which is coming at high velocity. As write operation in cassandra is very fast so it make it reliable to use it for real time scenarios where you have to process and modify the data in real time. And as Cassandra is built using Java, so it is easy to integrate this with other Java base tools like Spark, Hadoop etc.
Cons: Only cons for me is that it’s unpredictable performance because cassandra has lots of asynchronous jobs and other background job which are not in control. In such cases, troubleshooting some issue is big problem.

Quite good NoSql family Database
Deepak kumar S.
Comments: good and reliable NoSql family database .
Pros: As everything is designed for a specific problem to solve. Cassandra has it's own use cases where it perform very much reliably and efficiently. This is good when you have to capture high velocity traffic and need to do operation over it. Also, it offers other lots of great like very high writing speed, easy integration with other JVM based service/tool like spark, hadoop etc.
Cons: it has a quite bit hard of learning as you will have to setup the cluster for maintenance and all. And Cassandra is specific to use cases you just can't use it for other.

Ease of use with highly available , fault tolerant , distributed database
(1) It is highly available , also, replication around nodes is super fast
(2) It is fault tolerant inherently by design
(3) It is a distributed database, suitable for handling huge volumnes
Cons: Row level inconsistency sometimes poses problems with usage in Cassandra. This means when the same row is inserted and updated at the same time, there can be consistency issues with it.

High quality NoSQL database more closely related to relational DBs than alternatives
Pros: Compared to MongoDB, another NoSQL database, Cassandra's commands are more closely related to SQL and are consequently more approachable to SQL experts. As a NoSQL database, developers are not weighed down with designing and modifying schemas.
Cons: Compared to MongoDB, Cassandra is less flexible and resembles relational databases more than MongoDB does.

Intuitive for SQL user
Pros: The query language cql is quite intuitive specially for sql users. Setup is also very easy since they have extensive documentation. Cassandra also provides very good and easy to use APIs that can be easily integrated in any application.
Cons: It is a column oriented storage format which takes some time to get used specially for sql users.

If something seems too good to be true it probably is.
Pros: An easy way to share data across multiple clusters. A proper columnar data store, with some novel quorum modes.
Cons: No matter how it's configured it's impossible to have really durable data. Having fault tolerant synchronous modes is useless if a node can die because it ran out of journal space. This should never happen! If a node can't write it's journal it should freeze, not the loose consistency of its local data ( I'm talking about corruption here not the loss of consistency with the other nodes). Columnar formatting and retrieval are actually really inefficient. Data formats in anything other than simple storage are bloated and inefficient.

We use it on our team to provide cache functionalities with high success.
Comments: Amazing performance and great value.
Pros: The amount of features and bang-for-buck ratio is really great. Perfomance is really good too. The fact that it's a descentralized architecture also means uptime is great.
Cons: It may not be the easiest product to learn about and become proficient, but by no means should it be called inaccessible.

efficient and powerful nosql database
Pros: if your application or your project process data that can't be lost then cassandra is the right choice for you, your data is replicated into multiple nodes to prevent faults. You can scale your setup easly to accommodate your needs.
Cons: The learning curve is steep so be prepared to get a lot of headache while learning. It's painful but not impossible.
