About DataStax EnterpriseDataStax Enterprise is a big data platform built on Apache Cassandra that manages real-time, analytics, and enterprise search data. DataStax Enterprise leverages Cassandra, Apache Hadoop, Apache Spark, and Apache Solr to shift your focus from the data infrastructure to using your data strategically.

Managing securityManaging security in DataStax Enterprise including authentication, encryption, auditing, permissions, and configuration.
Security managementDataStax Enterprise includes advanced data protection for enterprise-grade databases including LDAP authentication support, internal authentication, object permissions, encryption, Kerberos authentication, and data auditing.
Authenticating with KerberosDataStax Enterprise authentication with Kerberos protocol uses tickets to prove identity for nodes that communicate over non-secure networks.
Authenticating a cluster with LDAPDataStax Enterprise supports LDAP authentication support for external LDAP services.
Client-to-node encryptionClient-to-node encryption protects data in flight from client machines to a database cluster. It establishes a secure channel between the client and the coordinator node.
Node-to-node encryptionNode-to-node encryption protects data that is transferred between nodes in a cluster using SSL (Secure Sockets Layer).
Spark SSL encryptionCommunication between Spark clients and clusters as well as communication between Spark nodes can be encrypted using SSL.
Server certificatesAll nodes requires relevant SSL certificates. Generate SSL certificates for client-to-node encryptions or node-to-node encryption.
Running cqlshSample files are provided to help configure authentication for Kerberos, SSL, and Kerberos and SSL.
Transparent data encryptionTransparent data encryption (TDE) protects at rest data. TDE requires a secure local file system to be effective.
Data auditingSet options in dse.yaml for configuring and using data auditing.
Internal authenticationInternal authentication is based on Cassandra-controlled login accounts and passwords.
Managing object permissionsUse GRANT/REVOKE to grant or revoke permissions to access Cassandra data.
Configuring keyspace replicationThe system_auth and dse_security keyspaces store security authentication and authorization information.
Configuring firewall portsIf a firewall runs on the nodes in the Cassandra or DataStax Enterprise cluster, open up ports to allow communication between the nodes.
Using the in-memory optionDataStax Enterprise includes the in-memory option for storing data to and accessing data from memory exclusively.
DSE AnalyticsDataStax Enterprise analytics includes integration with Apache Spark, Apache Shark, BYOH (bring your own Hadoop), and DSE Hadoop.
Introduction to DSE AnalyticsDataStax Enterprise serves the analytics market with significant features for analyzing huge databases.
Analyzing data using SparkSpark is the default mode when you start an analytics node in a packaged installation. Spark runs locally on each node.
Analyzing data using external Hadoop systems (BYOH)DataStax Enterprise (DSE) works with external Hadoop systems in a bring your own Hadoop (BYOH) model. Use BYOH when you want to run DSE with a separate Hadoop cluster, from a different vendor.
Analyzing data using DSE HadoopYou can run analytics on Cassandra data using Hadoop that is integrated into DataStax Enterprise. The Hadoop component in DataStax Enterprise enables analytics to be run across DataStax Enterprise distributed, shared-nothing architecture.
DSE Search featuresDSE Search provides enterprise search using Apache Solr in DataStax Enterprise. DSE Search enhancements include dsetool commands.
Getting Started with SolrDataStax Enterprise supports Open Source Solr (OSS) tools and APIs, simplifying migration from Solr to DataStax Enterprise.
Supported and unsupported featuresSupported and unsupported Cassandra and DSE Search features.
Defining key Solr termsSolr terms include several names for an index of documents and configuration on a single node.
DSE vs. Open sourceDifferences between DSE Search/Solr and Open Source Solr (OSS).
ArchitectureA brief overview and illustration of the DSE search architecture.
ConfigurationConfiguration and operations of the DSE Search include starting and stopping DSE Search, segregating workloads, indexing, querying, and creating a schema and data modeling.
QueryingA brief description and illustration of querying nodes with DSE search.
OperationsTopics for using and running Solr nodes.
Performance tuningTopics for performance tuning and solving performance degradation, high memory consumption, or other problem swith DataStax Enterprise Search nodes.
Update request processor and field transformerUse the custom update request processor (URP) to extend the Solr URP. Use the field input/output transformer API as an option to the input/output transformer support in OS Solr.
Tutorial: BasicsSetting up for the DSE Search tutorial includes creating a Cassandra node, importing data, and creating resources.
Tutorial: AdvancedThis DSE Search tutorial builds on the basic tutorial.
TroubleshootingTake appropriate action to troubleshoot inconsistent query results, tracing Solr HTTP requests, and using several Mbeans.
Wikipedia demoRun the Wikipedia demo on a single node to download Wikipedia articles, create a CQL table, store the articles, and index the articles in Solr.
Migrating dataMigrate data using Sqoop or other methods.
Migrating data using SqoopFor DSE Hadoop, use Sqoop to transfer data between an RDBMS data source and Hadoop or between other data sources, such as NoSQL.
Migrating data using other methodsMigrating data to DataStax Enterprise solutions include the COPY command, the DSE Search/Solr Data Import Handler, and the Cassandra bulk loader.
DeployingProduction deployment of DataStax Enterprise includes planning, configuration, and choosing how the data is divided across the nodes in the cluster.
Production deployment planningResources for deployment planning and recommendations for deployment.
Configuring replicationHow to set up DataStax Enterprise to store multiple copies of data on multiple nodes for reliability and fault tolerance.
Mixing workloadsOrganize nodes that run different workloads into virtual data centers. Put analytic nodes in one data center, search nodes in another, and Cassandra real-time transactional nodes in another data center.
Single data center deployment per workload typeSteps for configuring nodes in a deployment scenario in a mixed workload cluster that has only one data center for each type of workload.
Multiple data center deployment per workload typeSteps for configuring nodes in a deployment scenario in a mixed workload cluster that has more than one data center for each type of node.
Single-token architecture deploymentSteps for deploying when not using virtual nodes (vnodes).
Calculating tokens How to calculate tokens when using single-token architecture.
Expanding an AMI clusterTo expand your EC2 implementations, use OpsCenter to provision a new cluster, add a new cluster, or add nodes to a cluster.
DataStax Management ServicesDataStax Management Services automatically handle administration and maintenance tasks and assist with overall database cluster management.
Performance ServiceThe Performance Service automatically collects and organizes performance diagnostic information into a set of data dictionary tables that can be queried with CQL.
Capacity ServiceAutomatically collects data about a cluster's operations, including Cassandra specific and platform specific (for example, disk metrics, network metrics), at both the node and column-family level (where applicable). Use OpsCenter to manage and perform trend analysis.
Repair ServiceDesigned to automatically keep data synchronized across a cluster, you can manage the Repair Service with OpsCenter or by using the command line.
DataStax Enterprise toolsTools include dse commands, dsetool, dfs-stress tool, pre-flight check and yaml_diff tools, and the Cassandra bulk loader.
The dse commandsTable of common dse commands for using DataStax Enterprise.
The dsetoolUse the dsetool utility for Cassandra File System (CFS) and Hadoop-related tasks, such as managing the job tracker, checking the CFS, and listing node subranges of data in a keyspace.
The cfs-stress toolPerforms stress testing of the Cassandra File System (CFS) layer.
Pre-flight check and yaml_diff toolsThe pre-flight check tool is available for packaged installations. This collection of tests can be run on a node to detect and fix a configuration. The yaml_diff tool filters differences between cassandra.yaml files.
Common tasksCommon tasks for using DataStax Enterprise.
Configuration (dse.yaml)The configuration file for DataStax Enterprise.
