COMPACTION STRATEGIES, PERFORMANCE, AND THEIR IMPACT ON CASSANDRA NODE DENSITY
This is the third post in my series on optimizing Apache Cassandra for maximum cost efficiency through increased node density. In the first post, I examined how streaming operations impact node density and laid out the groundwork for understanding why higher node density leads to significant cost savings. In the second post, I discussed how compaction throughput is critical to node density and...
CASSANDRA COMPACTION THROUGHPUT PERFORMANCE EXPLAINED
This is the second post in my series on improving node density and lowering costs with Apache Cassandra. In the previous post, I examined how streaming performance impacts node density and operational costs. In this post, I’ll focus on compaction throughput, and a recent optimization in Cassandra 5.0.4 that significantly improves it, CASSANDRA-15452. This post assumes some familiarity with...
HOW CASSANDRA STREAMING, PERFORMANCE, NODE DENSITY, AND COST ARE ALL RELATED
This is the first post of several I have planned on optimizing Apache Cassandra for maximum cost efficiency. I’ve spent over a decade working with Cassandra and have spent tens of thousands of hours data modeling, fixing issues, writing tools for it, and analyzing it’s performance. I’ve always been fascinated by database performance tuning, even before Cassandra. A decade ago I...
