Antwort Is Cassandra DB still used? Weitere Antworten – Is Cassandra still being used
Twelve-plus years after its invention, Cassandra is now used by approximately 90 percent of the Fortune 100, and it's appeal is broadening quickly, driven by a rush to harness today's “data deluge” with apps that are globally distributed and always-on.With personality traits like that, it's not surprising that Cassandra has been one of the most popular databases since its release just over a decade ago – or that it's still used by the massive teams at companies like Apple, Uber, Netflix, and Spotify.Apache Cassandra has market share of 4.69% in nosql-databases market. Apache Cassandra competes with 20 competitor tools in nosql-databases category. The top alternatives for Apache Cassandra nosql-databases tool are MongoDB with 45.80%, NoSQL with 22.79%, Amazon DynamoDB with 10.04% market share.
When should you use Cassandra DB : Performance: Cassandra is suitable for use cases involving heavy data packet transmission between servers since it is optimise for high write throughput. Because of its ability to handle millions of writes per second, data is processed and stored quickly.
Does Netflix use Cassandra
Netflix started with a 12-node Cassandra cluster and scaled up to 24 nodes to support the current data size. Some Netflix titles have more than 3M annotations (most of which are subtitles). Currently, the service has around 1.9 billion annotations with a data size of 2.6TB.
Is Cassandra deprecated : As an always-on technology during major upgrades, Cassandra maintains compatibility across adjacent major versions. Cassandra does not break API compatibility without a deprecated grace period demarcated by major versions. Upgrades without downtime are supported from any major version to the next major version.
Cassandra is highly optimized for write-heavy workloads and can handle large volumes of data across many commodity servers. MongoDB offers robust performance for read-heavy workloads and is generally considered more versatile for a wider range of applications due to its document-oriented model.
Apache Cassandra has a more structured data storage system than MongoDB. If the data you're working with is in a fixed format, Cassandra is more suitable. If the data is more dynamic and doesn't have a consistent structure, MongoDB works better.
Does Apple still use Cassandra
Apple: Apple utilizes Cassandra to handle data for various internal applications and services, including iCloud, Apple Maps, and Siri. Uber: Cassandra powers critical components of Uber's infrastructure, such as real-time analytics, monitoring, and user data management, enabling seamless operations at a global scale.At least one cluster was over 1,000 nodes, and Apple regularly gets millions of operations per second (reads/writes) with Cassandra.Cassandra is more focussed on giving you stability, and hence like SQL, you can store huge data sets. But, it is slower in speed than that of Redis. Redis is much faster than Cassandra, but it gets slower if you use it for huge data sets and is ideally suited for rapidly changing datasets.
If the data you're working with is in a fixed format, Cassandra is more suitable. If the data is more dynamic and doesn't have a consistent structure, MongoDB works better.

What are the drawbacks of Cassandra : Drawbacks of Cassandra
It requires specialized knowledge to properly set up and configure, and optimizing performance can be challenging. Eventual consistency: Cassandra uses an eventually consistent data model, which means that there can be some delay between updates being made on different nodes.
Why does Netflix use Cassandra
The team at Netflix decided to choose Apache Cassandra as the source of truth for storing annotations. Cassandra is an open-source, wide-column store, NoSQL distributed database that provides horizontal scalability.
SQL is able to handle moderate storage. As Cassandra facilitates automatic distribution of data, it allows relatively fast data transfer to or from the storage. As SQL allows manual distribution of data, the speed of data transfer, in this case, is relatively slow than of Cassandra.MongoDB is a general-purpose database that can support multiple use cases with its flexible document model, rich aggregation language, and robust features such as sharding and ACID compliant transactions. Therefore, it can cover the vast majority of Cassandra's most popular use cases, and much more.
