Java's new Z Garbage Collector (ZGC) is very exciting
Java 11 has recently been feature frozen and contains some really great features, one in particular we’d like to highlight. The release contains a brand new Garbage Collector, ZGC, which is being developed by Oracle that promises very low pause times on multi-terabyte heaps. In this article we’ll cover the motivation for a new GC, a technical overview and some of the really exciting possibilities

Java GC, HotSpot's CMS and heap fragmentation
Concurrent Mark Sweep (CMS) is one of garbage collection algorithms implemented in HotSpot JVM. CMS is designed to be mostly concurrent, requiring just two quick stop-the-world pauses per old space garbage collection cycle. But if CMS cannot keep up with allocation of memory by application, it may fallback to stop-the-world whole heap collection - infamous Full GC pause. Full GC is very noticeable
Cassandra and Solid State Drives
This document discusses how Cassandra's storage engine was optimized for spinning disks but remains well-suited for solid state drives. It describes how Cassandra uses LSM trees with sequential, append-only writes to disks, avoiding the random read/write patterns that cause issues for SSDs like write amplification and reduced lifetime from excessive garbage collection. While SSDs have benefits lik
