Cassandra 5.0 Features that You Can’t Miss 

Here are some of the features that will tag along with the new version of Apache Cassandra that has the potential to revolutionize Big Data:

Storage Attached Indexes

Cassandra 5.0’s innovative Storage-Attached Indexing (SAI) enhances secondary index lifecycle management, making it more efficient and user-friendly. With SAI, users can create multiple secondary indexes on a database table, each based on a specific column of their choice.

This scalable, globally distributed column-level indexing provides unparalleled I/O throughput for searches, including Vector Search. SAI also boasts modular extensibility, with Vector Search as a prime example. These indexes can capture semantics by indexing both queries and content (such as documents and images), achieving exceptional indexing functionality.

Trie Memtables and Trie SSTables

Cassandra 5.0 introduces significant performance enhancements and memory optimizations through its new trie (prefix tree)–based Memtables and SSTables. These advanced storage formats utilize tries and byte-comparable representations of database keys to boost performance for read and write operations and to accurately size structures according to the data. Trie Memtables and Trie-Indexed SSTables also alleviate memory management overhead and reduce the burden of garbage collection, simplifying data management for high-scale organizations.

In short, these improvements in storage efficiency, scalability, and read/write performance are poised to garner significant attention and appreciation from Cassandra users.

New Mathematical CQL Functions

Cassandra 5.0 releases new native CQL functions and the capability for users to create custom user-defined functions, enhancing the speed and flexibility with which users can achieve their key objectives.

The new native aggregation functions include:

• count: Determines the number of items in a collection.
• max and min: Identify the maximum or minimum items in a collection.
• sum and avg: Calculate the sum or average of items in a numeric collection.

New native functions for operating on collection columns include:

• map_keys: Retrieves the keys of a map.
• map_values: Retrieves the values of a map.

New native mathematical functions include:

• abs: Returns the absolute value of the input.
• exp: Computes e (the base of natural logarithms) raised to the power of the input.
• log: Computes the natural logarithm (base e) of the input.
• log10: Computes the base 10 logarithm of the input.
• round: Rounds the input to the nearest integer.

These additions significantly enhance Cassandra’s functionality, providing users with greater capability and efficiency in their database operations.

Unified Compaction Strategy

Cassandra 5.0 introduces the unified compaction strategy, designed to simplify operations for administrators. This innovative strategy merges the tiered and leveled compaction strategies into a single, configurable algorithm. The unified compaction strategy also paves the way for future enhancements, including automatic tuning and intelligent optimizations.

While this feature offers significant benefits, thorough testing is recommended before deploying it in a production environment. Compaction is a critical function in Cassandra, and improper use can lead to excessive resource consumption, adversely affecting query performance. Therefore, careful evaluation and testing are essential to ensuring optimal results.

Vector Search

Vector Search will be a powerful feature for efficient content retrieval within large datasets. With new CQL functions and a VECTOR data type for managing embedding vectors, this update positions Cassandra as an ideal solution for AI/ML projects. Vector Search, leveraging Approximate Nearest Neighbor (ANN) technology through Storage Attached Indexes, enhances similarity comparisons critical for AI applications like recommendation engines and chatbots. Explore the documentation to leverage these capabilities for advanced AI application development.

Dynamic Data Masking

Another feature you can look for is Dynamic Data Masking (DDM). It obscures sensitive information in database columns. DDM operates by applying “masks” to columns, transforming the data visible in SELECT queries without altering the underlying data. Built-in masks include default value replacement, data shuffling, and partial redaction. This capability enhances data security by reducing the risk of accidental exposure through queries.

CIDR Authorizer

Cassandra 5.0 introduces the CIDR authorizer feature, which restricts database access based on client IP address ranges defined using Classless Inter-Domain Routing (CIDR) notation. This feature enables network-level access control, ensuring that only specified IP ranges can access particular data or operations. It is a critical security enhancement for multi-tenant and public cloud environments where network isolation may not be assured.

Things You Should Expect From New Version

Here are 5 things you can expect from Cassandra 5.0 that will affect your business growth:

1. Improved Performance: Cassandra 5.0 introduces trie-based memtables and SSTables, which optimize memory and storage usage, leading to faster reads, writes, and overall better performance.
2. Storage Attached Indexes (SAIs): SAIs are a game-changer for query performance. By storing indexes alongside data, Cassandra can retrieve information much faster, making it ideal for workloads that require fast and efficient data access.
3. Vector Support: Cassandra 5.0 embraces the world of AI and machine learning by introducing vector data types and vector search capabilities. This allows you to store and search for high-dimensional data, which is crucial for applications like natural language processing and recommendation systems.
4. Enhanced Manageability: Cassandra 5.0 will also help in forming an unified compaction strategy, simplifying cluster administration and reducing operational overhead. Additionally, features like dynamic data masking improve security by allowing you to redact sensitive information during queries.
5. Open Source Focus: The Cassandra project remains committed to open source development, ensuring a strong community, ongoing innovation, and continued support for this powerful NoSQL database.
