Antwort Is Cassandra still relevant? 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 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.
Is Cassandra worth it : Choosing between Cassandra and MongoDB depends on your project's specific requirements and characteristics. Cassandra might be better if you need a highly scalable, distributed database optimized for write-heavy workloads and strong consistency.
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.
Data Storage — MySQL and Cassandra
On the other hand, Netflix uses Apache Cassandra for use-cases demanding heavy read and write operations. Cassandra's distributed architecture and high write performance make it an excellent choice for maintaining users' viewing history.
While MySQL is a go-to choice for traditional relational database requirements, Cassandra is more apt for handling large-scale, distributed, and high-throughput environments. The choice between the two should be based on specific application requirements, data structures, and scalability needs.
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.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.
Other important factors to consider when researching alternatives to Cassandra include availability and performance. We have compiled a list of solutions that reviewers voted as the best overall alternatives and competitors to Cassandra, including ScyllaDB, Redis, Amazon DynamoDB, and ArangoDB.
Does Spotify use Cassandra : Spotify utilizes Apache Cassandra in its infrastructure to serve data behind a personalization algorithm, which recommends songs to its users.
When not to use Apache Cassandra : When we want many-to-many mappings or joins between tables. Cassandra doesn't support a relational schema with foreign keys and join tables. So if we want to write a lot of complex join queries, then Cassandra might not be the right database for us.
Is Cassandra good for big data
Cassandra's ability to handle large-scale data sets with low-latency performance makes it a popular choice in industries such as finance, healthcare, and telecommunications. As an open-source solution, Cassandra empowers developers with flexibility and adaptability for building robust, distributed database systems.
There is a tendency to think of Apache Cassandra as a platform for huge companies. However, there are use cases for midsize companies as well. Apache Cassandra tends to get "pigeonholed [as] this very, very large-scale type of workload. It's the platform that Netflix is built on.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.
