Ideally, both the ZooKeeper transaction log and Cassandra data files need their own dedicated disks, with additional disks for other services on the host. Open source database technology has matured to the point where it is now being used widely in financial, eCommerce, and payment processing applications. ZooKeeper is an open-source platform that offers a centralized infrastructure for maintaining configuration information, naming, providing distributed synchronization, and providing group services. The framework helps to automate installation, running and scaling of the system. Development sites (sites where applications are built) and production sites (sites where the applications run) have different load profiles, scaling characteristics, and performance demands and so are broken out separately. Thus, configuring ports to use 0 instead of an explicit value, should, in most cases, work around any issues of running multiple distinct Accumulo instances (or any other process which tries to use the same default ports) on the same hardware. For high-load scenarios, a 24-core CPU, 64 GB RAM or higher is recommended. Apache Kafka on Heroku offers a CLI tool that can be used to cause one of the nodes in your cluster to fail.
