Getting started
Information about developing applications for DataStax Enterprise.
Release notes
Release notes for DataStax Enterprise.
Installing
DataStax Enterprise 6.0 can be installed in a number of ways, depending on the purpose of the installation, the type of operating system, and the available permissions.
Configuration
Information about configuring DataStax Enterprise, such as recommended production setting, configuration files, snitch configuration, start-up parameters, heap dump settings, using virtual nodes, and more.
- Recommended production settings
  Recommended settings for Linux platforms on DataStax Enterprise.
- YAML and configuration properties
  Information on how to configure DataStax Enterprise using the cassandra.yaml, dse.yaml, cassandra-rackdc.properties, and cassandra-topology.properties files.
- Cloud provider snitches
  Set up Ec2Snitch, Ec2MultiRegionSnitch, GoogleCloudSnitch, or CloudstackSnitch.
- JVM system properties
  Modify DataStax Enterprise system properties from the startup command line or file.
- Choosing a compaction strategy
  How to choose the best compaction strategy.
- NodeSync service
  Continuous background repair that virtually eliminates manual efforts to run repair operations in a DataStax cluster.
  - About NodeSync
    Easy to use continuous background repair that has low overhead and provides consistent performance and virtually eliminates manual efforts to run repair operations in a DataStax cluster.
  - Starting and stopping the NodeSync service
    NodeSync service automatically starts with the dse cassandra command. You can manually start and stop the service on each node.
  - Enabling NodeSync validation
    Continuously verify data consistency in the background without performing anti-entropy repairs.
  - Tuning NodeSync validations
    Configure validation rate to meet target deadlines.
  - Manually starting NodeSync validation
    Force NodeSync to repair specific segments, a small token range of a table.
- Configuring Virtual Nodes
  Topics about setting up and enabling virtual nodes (vnodes).
DSE advanced functionality
Information on using DSE Analytics, DSE Search, DSE Graph, DSEFS (DataStax Enterprise file system), and DSE Advanced Replication.
Tools
Tools include dse commands, dsetool, fs-stress tool, pre-flight check, and yaml_diff tools, and the sstableloader.
Operations
DataStax Enterprise operation topics, such as node and datacenter operations, changing replication strategies, configuring compaction and compression, caching, and tuning Bloom filters.
CQL
CQL (Cassandra Query Language) is a query language for the DataStax Enterprise database.
