DSE 6.7 Developer Guide

Getting started
Information about developing applications for DataStax Enterprise.
Release notes
Release notes for DataStax Enterprise.
Installing
DataStax Enterprise 6.7 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.
DSE advanced functionality
Information on using DSE Analytics, DSE Search, DSE Graph, DSEFS (DataStax Enterprise file system), and DSE Advanced Replication.
- DSE Analytics
  DataStax Enterprise 6.7 Analytics includes integration with Apache Spark.
- DSE Search
  DSE Search allows you to quickly find data and provide a modern search experience for your users, helping you create features like product catalogs, document repositories, ad-hoc reporting engines, and more.
- DSE Graph
  Documentation for developers and administrators on installing, configuring, and using the features and capabilities of DSE Graph.
- 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 NodeSync validation rate to meet target deadlines.
  - Manually starting NodeSync validation
    Force NodeSync to repair specific segments, a small token range of a table.
- DSE Advanced Replication
  Documentation for configuring and using configurable distributed data replication.
Developing applications with DataStax drivers
The DataStax drivers are the primary resource for application developers creating solutions using DataStax Enterprise (DSE).
Tools
Tools include nodetool, dse, and dsefs shell 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.
