Apache Cassandra™ 3.x

About Apache Cassandra
Documentation for developers and administrators on installing, configuring, and using the features and capabilities of Apache Cassandra scalable open source NoSQL database.
Understanding the architecture
Important topics for understanding Cassandra.
Database internals
Topics about the Cassandra database.
Planning a cluster deployment
Vital information about successfully deploying a Cassandra cluster.
Installing
Various installation methods.
Configuration
Configuration topics.
Initializing a cluster
Topics for deploying a cluster.
Operations
Cassandra operation topics, such as node and datacenter operations, changing replication strategies, configuring compaction and compression, caching, and tuning Bloom filters.
Cassandra tools
Topics for Cassandra tools.
- The nodetool utility
  A list of the available commands for managing a cluster.
- The cassandra utility
  You can start Cassandra 3.2 and later with special parameters by adding them to the jvm.options file (package or tarball installations) or by entering them at the command prompt (in tarball installations).
- The cassandra-stress tool
  A Java-based stress testing utility for basic benchmarking and load testing a Cassandra cluster.
- SSTable utilities
  Tools for using, upgrading, and changing Cassandra SSTables.
  - sstabledump
    Dump the contents of the specified SSTable in JSON format
  - sstableexpiredblockers
    The sstableexpiredblockers utility will reveal blocking SSTables that prevent an SSTable from dropping.
  - sstablekeys
    The sstablekeys utility dumps table keys.
  - sstablelevelreset
    The sstablelevelreset utility will reset the level to 0 on a given set of SSTables.
  - sstableloader (Cassandra bulk loader)
    Provides the ability to bulk load external data into a cluster, load existing SSTables into another cluster with a different number of nodes or replication strategy, and restore snapshots.
  - sstablemetadata
    The sstablemetadata utility prints metadata about a specified SSTable.
  - sstableofflinerelevel
    The sstableofflinerelevel utility will relevel SSTables.
  - sstablerepairedset
    The sstablerepairedset utility will reset the level to 0 on a given set of SSTables.
  - sstablescrub
    An offline version of nodetool scrub. It attempts to remove the corrupted parts while preserving non-corrupted data.
  - sstablesplit
    Use this tool to split SSTables files into multiple SSTables of a maximum designated size.
  - sstableupgrade
    Upgrade the SSTables in the specified table or snapshot to match the currently installed version of Cassandra.
  - sstableutil
    The sstableutil utility will list the SSTable files for a provided table.
  - sstableverify
    The sstableverify utility will verify the SSTable for a provided table.
Troubleshooting
Release notes
