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 KerberosAn overview of Kerberos in DataStax Enterprise and recommendations.
Client-to-node encryptionClient-to-node encryption protects data in flight from client machines to a database cluster.
Node-to-node encryptionNode-to-node encryption protects data that is transferred between nodes in a cluster using SSL (Secure Sockets Layer).
Server certificatesGenerate SSL certificates for client-to-node encryptions or node-to-node encryption.
Running cqlshSample files for Kerberos, SSL, and Kerboros and SSL.
Transparent data encryptionTransparent data encryption (TDE) protects at rest data. TDE requires a secure local file system to be effective.
Data auditingAuditing is implemented as a log4j-based integration.
Internal authenticationInternal authentication is based on Cassandra-controlled login accounts and passwords. You can authenticate uses of Hadoop tools, Spark-to-Cassandra connections, and Shark configuration changes.
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 portsOpening the required 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.
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 DSE Search and Solr features.
Defining key Solr termsSolr terms include several names for an index of documents and configuration on a single node.
Installing Solr nodesInstalling and starting and stopping Solr nodes.
Solr tutorialSteps for setting up Cassandra and Solr for the tutorial.
Configuring SolrConfigure Solr Type mapping.
Creating an index for searchingRequirements and steps for creating a Solr index.
Using DSE Search/SolrA brief description and illustration of DSE Search.
Querying Solr dataA brief description about query Solr data.
Capacity planningUse a discovery process to develop a plan to ensure sufficient memory resources.
Segregating workloadsAbout using real-time (Cassandra), integrated Hadoop or Spark/Shark (Analytics), an external Hadoop system, or search (Solr) nodes in the same cluster.
Common operationsTopics for using DSE Search.
Tuning DSE Search performanceTopics for performance tuning and solving performance degradation, high memory consumption, or other problem swith DataStax Enterprise Search nodes.
Solr MBeansThe solr/NativeAllocatorStats MBean exposes native memory allocation.
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.
DSE vs. Open sourceA comparison of DSE Search and Open Source Solr.
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 data using SqoopMigrating data using Sqoop topics.
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.
Production deployment planningProduction deployment planning requires knowledge of the initial volume of data to store and an estimate of the typical application workload.
Configuring replicationChoose a data partitioner and replica placement strategy.
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 typeA deployment scenario with a mixed workload cluster has only one data center for each type of workload.
Multiple data center deployment per workload typeA deployment scenario with a mixed workload cluster has more than one data center for each type of node.
Single-token architecture deploymentUse single-token architecture deployment when you are not using virtual nodes (vnodes).
Calculating tokens Tokens assign a range of data to a particular node within a data center.
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 ServicePerformance Service topics.
Capacity ServiceThe Capacity Service automatically collects data about a cluster’s operations and provides for the ability to do historical trend analysis and forecasting of future trends.
Repair ServiceThe Repair Service is designed to automatically keep data synchronized across a cluster and can be managed either visually through OpsCenter or via the command line.
DataStax Enterprise toolsTools include dse commands, dsetool, dfs-stress tool, pre-flight check, yaml_diff, and the Cassandra bulk loader.
The dse commandsTable of 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.
Configuration (dse.yaml)The configuration file for Kerberos authentication, purging of expired data from the Solr indexes, setting Solr inter-node communication, adjusting disk health intervals, and enabling the Performance Service.
