DSE advanced functionality
Information on using DSE Analytics, DSEFS, DSE Search, DSE Graph, DSE Advanced Replication, DSE In-Memory, DSE Multi-Instance, DSE Tiered Storage and DSE Performance services.
Tools
Tools include nodetool, dse commands, dsetool, cfs-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
  A list of the available commands for managing a cluster.
- dse commands
  The dse commands for starting the database and connecting an external client to a DataStax Enterprise node and performing common utility tasks.
- dse client-tool
  Connects an external client to a DataStax Enterprise node and performs common utility tasks.
- dsetool
  A list of the available commands for DSE operations.
- Stress tools
  Tools for stress testing DataStax Enterprise.
- SSTable utilities
  Tools for using, upgrading, and changing DataStax Enterprise SSTables.
  - sstabledump
    Dumps contents of given SSTable to standard output in JSON format.
  - sstableexpiredblockers
    A diagnostic tool that reveals blocking SSTables that prevent an SSTable from dropping.
  - sstablelevelreset
    Resets the level to zero on a set of SSTables.
  - sstableloader
    Bulk loads external data into a cluster, load existing SSTables into another cluster with a different number of nodes or replication strategy, and restore snapshots.
  - sstablemetadata
    Utility for printing metadata about a specified SSTable.
  - sstableofflinerelevel
    Relevels SSTables offline.
  - sstablepartitions
    Identifies large partitions of SSTables.
  - sstablerepairedset
    Utility for resetting the level to zero 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
    Splits SSTables files into multiple SSTables of a maximum designated size.
  - sstableupgrade
    Upgrade the SSTables in the specified snapshot to match the currently installed version of DataStax Enterprise.
  - sstableutil
    Lists the SSTable files for a designated table.
  - sstableverify
    Verifies the SSTable for a designated table.
- Preflight check tool
  The preflight check tool is a collection of tests that detects and optionally fixes configuration settings on DataStax Enterprise nodes.
- cluster_check and yaml_diff tools
  Using the cluster_check and yaml_diff tools to check 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.
Planning
Hardware selection, estimating disk capacity, anti-patterns, cluster testing and more.
