I have used Cassandra for several months for my research project that included storing unstructured data. I found it a little bit more difficult to use than Amazon DynamoDB, but given that it is the open source project I was thoroughly impressed by all the features and the reliability of Cassandra. I would recommend Cassandra for projects using Open Source technologies. It is very fast and met all of the efficiency metrics and agreements for the project I have been developing. Cons I found it a little bit harder to work with compared to MongoDB and DynamoDB. Nevertheless I believe that for an experienced engineer who has worked with Databases before, it will take couple of weeks to get fully fluent with Cassandra docs. Alternatives considered [MongoDB](https://www.capterra.com/p/127374/MongoDB/) Switched from [MongoDB](https://www.capterra.com/p/127374/MongoDB/) I wanted to explore other open source solutions.

M. CTO Internet Used the software for: 2+ years ### "It was good, until we hit GC" July 1, 2018 1.0 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. Cons 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.

January 28, 2018 5.0 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. Review Source Suru S. BigData Engineer Information Technology and Services Used the software for: 1-2 years ### "A highly available and a consistent flavour of NoSQL Databases" February 21, 2023 4.0 Been using it and will continue to use it for our Data Engineering needs that involves storing of huge amount of data with a lot of r/w operations we perform every week. Pros It is really beneficial for faster write operations and fast read search type queries that can be used in a pipeline with a high velocity of Read/Write operations. Management of data is carried out well by Cassandra and provides replication with its replication factor and replication strategy to prevent data loss. Cons Apache Cassandra is not meant for analytical queries and it cannot perform certain aggregation functions, Joins like other databases can. Review Source PJ Peter J. Architect Outsourcing/Offshoring Used the software for: 2+ years ### "Timeseries Database" February 9, 2021 3.0 Looks good on paper but has been very costly in terms of required resources to finally manage the load. Training material is limited and people with real experience are scarce. Pros Opensource license provides an easy cost entry point Programmatic support for our purpose was very good. Cons There is only one commercial version of this product and licensing is high. It can consume far more resources to handle the workload you give it than spec data suggests Alternatives considered [MongoDB](https://www.capterra.com/p/127374/MongoDB/) Reason for choosing Apache Cassandra It was selected as the best fit on paper however without a real world run off between the two we missed some apparent weaknesses Review Source VR Verified Reviewer Adjunct Lecturer Higher Education Used the software for: 2+ years ### "lightning fast key store" November 5, 2018 4.0 we needed to build a scalable object store with high write load (write is the main pattern of usage) Pros csql syntax is powerful lightning fast read/writes smart client to reduce hops to the correct node easy to install Cons cluster management complexity problematic node recovery Review Source VR Verified Reviewer Production Support Engineer Information Technology and Services Used the software for: 2+ years ### "Cassandra " February 12, 2019 5.0 Pros CASSANDRA is easy to use, easy to search objects based on key space values Cons Cassandra needs to improve their architecture and also provide more training videos Review Source Jatin G. Sr. Engineer Retail Used the software for: 1-2 years ### "Awesome No SQL DB" November 27, 2019 5.0 Pros The is awesome tool for No SQL DB requirements. We use this to store transactions so that we can reprocess in case something goes down. Cons The Queries are little tough and most of the features of sql queries are not supported. Review Source Gaurav Y. Software Developer Computer Software Used the software for: 6-12 months ### "good option from NoSql family database" January 15, 2019 5.0 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. Review Source KS Krishnamurthy S. Self employed Information Technology and Services Used the software for: I used a free trial ### "A good tool for NOSQL database" April 8, 2023 5.0 Overall a nice tool and I suggest using it for NOSQL database users Pros Cassandra stores data in a column-family format, which is a key-value pair-based storage model. In Cassandra, data is organized into column families, which are similar to tables in a relational database management system. Cons One potential challenge with Cassandra is its complexity. Cassandra has a steep learning curve compared to traditional relational databases, and it requires a deep understanding of its underlying data model, query language, and distributed architecture. Review Source Eyamir U. Profesora Used the software for: 6-12 months ### "It has been a pleasant and rewarding experience for the management of data in the cloud and totally " May 4, 2018 5.0 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. Review Source PJ Piyush J. Software Engineer Computer Software Used the software for: 2+ years ### "Cassandra Use Cases and Deployment Scope" October 11, 2016 5.0 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. Pros 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. Cons 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. Review Source AG Alpeshkumar G.

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. Review Source VS Vinicius S. Software Engineer Information Technology and Services Used the software for: 1-2 years ### "Review for Apache Cassandra" April 6, 2022 4.0 Allow users to process large volumes of data, in a scalable and reliable way. It's a fast NoSQL distributed database. Pros Easy to download, install, deploy and use. Cons Need heavy efforts for training new users. Alternatives considered [MongoDB](https://www.capterra.com/p/127374/MongoDB/) Reason for choosing Apache Cassandra Costs and vast documentation. Review Source VR Verified Reviewer Software Engineer Computer Software Used the software for: Less than 6 months ### "Available at all times" March 12, 2023 4.0 Pros It is designed to handle large amounts of data and can scale to support thousands of nodes across multiple data centers. And of course, it is open source which is a plus. Cons It is a complex database system that requires a high level of expertise to set up and maintain. It can be difficult to configure and optimize. Review Source FA Fırat A. CEO Information Technology and Services Used the software for: 6-12 months ### "Not exactly good" September 13, 2022 3.0 It won't take long to learn to use it because if you're an entry-level SQL user, you'll have mastered the entire software in about 10 minutes. Pros Basically, if you need a database software, you can use it, but you need to be a novice in this business to be extremely satisfied. It needs more improvement and the price should be a little cheaper. Cons Its overall quality should be improved, Simple shortcuts and special complications added. Its price and payment methods need to be updated, it needs more attention but once the minor glitches are cleared I have no doubt you will release a great piece of software. Review Source VR Verified Reviewer DBA Used the software for: 2+ years ### "If something seems too good to be true it probably is." March 24, 2018 2.0 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. Review Source OD Osman D.

Cons Apache Cassandra has not translaction support Review Source VR Verified Reviewer VP Financial Services Used the software for: 2+ years ### "Great Columnar Nosql Database - Cassandra" October 10, 2020 4.0 Overall it has been a wonderful experience using Cassandra with very low/none downtime to High availability and partition tolerance behavior Pros \- High availability as no master slave concept - Partition tolerance of the system - Replication across multi data centers Cons \- Upgrade to a higher version is non-trivial and requires a lot of testing and evaluation - Cqlsh query results not formatted well which creates confusion in reading Review Source MD Mallikarjuna D. Lead consultant Information Technology and Services Used the software for: 6-12 months ### "Review on Cassandra" September 12, 2020 4.0 I would strongly recommend this software for using distributing systems Pros As a user I would like it handle big data workflows across multiple nodes without any single point of failure .and it’s acting like a distributor among all the clusters Cons It have a capability when nodes goes down read and write request will be stored in other node with in network Review Source VR Verified Reviewer Founder and CEO Computer Software Used the software for: 6-12 months ### "High quality NoSQL database more closely related to relational DBs than alternatives" December 5, 2018 4.0 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. Review Source Abhisha B. Research Assistant Higher Education Used the software for: 6-12 months ### "Intuitive for SQL user" July 27, 2019 4.0 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.
