DS201.20 Advanced Performance | Foundations of Apache Cassandra
Updated: January 21, 2025
Summary
Datastax Enterprise 6 introduces performance enhancements by utilizing cores within a single machine, assigning one thread per core for efficient task handling. Scaling vertically provides performance gains for each node, while adding more nodes scales horizontally. This threaded architecture benefits from more cores per CPU, ensuring optimal performance and asynchronous operations without Lock Contention. With these advanced improvements, Datastax Enterprise 6 offers enhanced efficiency and operations for users.
Introduction to Datastax Enterprise 6
Datastax Enterprise 6 introduces performance gains with a shift in architecture, utilizing cores within a single machine.
Scaling Datastax Enterprise
Adding more nodes scales Datastax Enterprise horizontally, while each node obtains performance gains in scaling vertically.
Thread Assignment in Datastax Enterprise 6
Datastax Enterprise 6 assigns one thread per core on the machine, creating one thread per task and utilizing thread recycling within a pool.
Advantages of Threaded Architectures
Threaded architectures benefit from more cores per CPU instead of faster CPUs, avoiding excessive overhead by managing fewer threads for efficient progress.
Optimization in Datastax Enterprise 6
Datastax Enterprise 6 ensures optimal performance by creating one thread per core, enabling asynchronous writes and reads without Lock Contention, while leaving one core available for specific tasks.
