DSE 6.7 Developer Guide (EOSL)

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.
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.
- DSE Metrics Collector
  DSE Metrics Collector aggregates DSE metrics and integrates with centralized monitoring solutions to facilitate problem resolution and remediation.
- nodetool
  Available commands for monitoring a cluster and performing routine database operations.
- dse commands
  The dse commands for starting the database and connecting an external client to a DataStax Enterprise node and performing common utility tasks.
- dsefs shell commands
  The DSEFS functionality supports operations including uploading, downloading, moving, and deleting files, creating directories, and verifying the DSEFS status.
- dsetool
  A list of the available commands for DSE operations.
- Stress tools
  Tools for stress testing DataStax Enterprise.
- SSTable tools
  Available diagnostic tools for analyzing, using, upgrading, and changing DataStax Enterprise SSTables.
  - Get information
    Use these SSTable tools to get information about your SSTables.
    - sstabledump
      Dumps contents of given SSTable to standard output in JSON format.
    - sstableexpiredblockers
      Outputs the SSTables that prevent an SSTable from dropping.
    - sstablemetadata
      Prints metadata about given SSTable or SSTables to standard output.
    - sstablepartitions
      Identifies large partitions of SSTables.
    - sstableutil
      Lists SSTable files for the provided table.
  - Perform operations
    Use these SSTable tools to perform operations on your SSTables.
  - Ensure data consistency
    Use these SSTable tools to ensure data consistency on your SSTables.
- Preflight check tool
  The preflight check tool is a collection of tests that detects and optionally fixes configuration settings on DataStax Enterprise nodes.
- Compare yaml files
  cluster_check and yaml_diff compare the differences between cassandra.yaml or dse.yaml files.
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.
