Titan: Cassandra vs. Hazelcast persistence benchmark

That’s a really interesting benchmark. Continue to grow my convictions about Hazelcast and its capabilities.

Matt Pouttu-Clarke's Blog

10 node load test comparison using Amazon EC2 SSD-based instances.  1 billion vertices and 1 billion edges processed for each test run.  Used the titan-loadtest project to run each test.

Method

Experiment maximizes data locality by co-locating load generation, Titan graph database, and Cassandra/Hazelcast within the same JVM instance while partitioning data across a cluster. Exploration of methods for tuning garbage collection, Titan, and Cassandra for the peer computing use case.

The following components were utilized during the experiment:

Technology Version
RHEL x64 HVM AMI 6.4
Oracle JDK x64 1.7_45
Apache Cassandra 1.2.9
Hazelcast 3.1.1
Titan 0.3.2

Each test iteration has 6 read ratio phases starting with 0% reads (100% writes) all the way up to 90% reads and 10% writes.  For all tests, the persistence implementation executes in the same JVM as Titan to avoid unnecessary context switching and serialization overhead.  Tests were conducted using an Amazon placement…
