Why Cassandra is better 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.This article explores the key benefits of Apache Cassandra that make it a go-to solution for handling big data.

  • Distributed Architecture.
  • Scalability.
  • Fault Tolerance.
  • High Performance.
  • Tunable Consistency.
  • Flexible Data Storage.
  • Cassandra Query Language (CQL)
  • Active Everywhere Design.

Its decentralized design allows for seamless scalability, making it an ideal choice for applications requiring rapid growth. 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.

What is Cassandra best for : Cassandra works really well if we want to write and store a large amount of data in a distributed system and don't care much about ACID with good performance.

Which is faster Cassandra or MongoDB

Performance and scalability comparison

However, Cassandra is better suited for write-heavy workloads, while MongoDB is better suited for read-heavy workloads. Cassandra's masterless architecture allows for faster writes, while MongoDB's document-oriented data model allows for faster reads.

Why is Cassandra so popular : Cassandra is built to run at scale and be available across multiple regions, geographies or cloud providers. With developers and CIOs alike all looking at flexible deployments, Cassandra meets a huge need around managing data.

In the “MongoDB vs. Cassandra” comparison, there is no clear winner in terms of performance, because high throughput is more important for some applications, and low latency for others. The vanilla configurations of the two databases compare well in terms of their consistency level.

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.

Why is Cassandra so fast

Memtable: By storing recently written data in the memtable, Cassandra allows for read operations to be served from memory, which is much faster than reading from disk.Drawbacks of Apache Cassandra

  • Complexity: Apache Cassandra is a distributed system that requires a lot of expertise to operate efficiently.
  • No support for complex transactions: Apache Cassandra does not support complex transactions.
  • Limited query support: Apache Cassandra supports a limited set of query operations.

Cassandra is considered a fast database system due to its distributed architecture, data replication, and lack of a single point of failure. Writes are fast due to the use of a commit log and asynchronous write model, while reads are fast due to the use of a memtable and bloom filtering.

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 Netflix still using Cassandra : Netflix still uses Cassandra today, but not only for its scalability and rock-solid reliability. Its performance is key to the streaming media company – Cassandra runs 30 million operations per second on its most active single cluster, and 98% of the company's streaming data is stored on Cassandra.

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.

Why does Spotify use Cassandra

Spotify utilizes Apache Cassandra in its infrastructure to serve data behind a personalization algorithm, which recommends songs to its users.

According to Aeschylus, Cassandra promised Apollo favors, but, after receiving the gift, went back on her word and refused Apollo. Since the enraged Apollo could not revoke a divine power, he added a curse that nobody would believe Cassandra's prophecies.Cassandra is great when you have large workload that involves many writes but few reads such as storing and scaling millions of daily logs or sensor or IoT events . Cassandra has some limitations related to reading the data such as querying, searching, sorting or performing large scale aggregations or ad-hock queries.

Do people still use Cassandra : Cassandra, with its distributed architecture, was a natural choice, and by 2013, most of Netflix's data was housed there. Netflix still uses Cassandra today, but not only for its scalability and rock-solid reliability.
