Configuration
Configuration
Configuration topics.
The cassandra.yaml configuration file
The cassandra.yaml file is the main configuration file for Cassandra.
Configuring gossip settings
Using the cassandra.yaml file to configure gossip.
Configuring the heap dump directory
Analyzing the heap dump file can help troubleshoot memory problems.
Configuring the buffered read size
Configuring the buffered read size can reduce problems with wasted disk I/) and unnecessary garbage collection.
Configuring virtual nodes
Topics about configuring virtual nodes.
Using multiple network interfaces
Steps for configuring Cassandra for multiple network interfaces or when using different regions in cloud implementations.
Configuring logging
About Cassandra logging functionality using Simple Logging Facade for Java (SLF4J) with a logback backend.
Commit log archive configuration
Cassandra provides commit log archiving and point-in-time recovery.
Generating tokens
If not using virtual nodes (vnodes), you must calculate tokens for your cluster.
Hadoop support
Cassandra support for integrating Hadoop with Cassandra.
