Documentation for developers and administrators on configuring, and using the features and capabilities of Apache Cassandra.
An overview of new features in Apache Cassandra.
Cassandra Query Language (CQL) is the default and primary interface into the Cassandra DBMS.
Important topics for understanding Cassandra.
Vital information about successfully deploying a Cassandra cluster.
Various installation methods.
Topics for deploying a cluster.
Topics for securing Cassandra.
Topics about the Cassandra database.
Configuration topics.
Operation topics.
Monitoring topics.
Cassandra uses Bloom filters to determine whether an SSTable has data for a particular row.
Data caching topics.
Cassandra includes integrated caching and distributes cache data around the cluster. The integrated architecture facilitates troubleshooting and the cold start problem.
Use nodetool to make changes to cache options and then monitor the effects of each change.
Configuring memtable throughput to improve write performance.
Steps for configuring compaction. The compaction process merges keys, combines columns, evicts tombstones, consolidates SSTables, and creates a new index in the merged SSTable.
Compression maximizes the storage capacity of Cassandra nodes by reducing the volume of data on disk and disk I/O, particularly for read-dominated workloads.
Enabling write survey mode.
Tuning the Java Virtual Machine (JVM) can improve performance or reduce high memory consumption.
Correcting a problem in the gossip state.
Node repair topics.
Topics for adding or removing nodes, datacenters, or clusters.
Cassandra backs up data by taking a snapshot of all on-disk data files (SSTable files) stored in the data directory.
Topics for Cassandra tools.
Reference topics.
Solutions for migrating from other databases.
How to find the Apache Cassandra release notes.
