Dse spark
In DSE 5.1, we introduced 2x compaction performance over Apache Cassandra. In DSE 6, compaction is even faster. 40k fixed throughput test, 3 nodes, RF=3, CL=QUORUM Faster Analytics Scans Also included in DSE Advanced Performance are improved analytics read performance that is 3x over open source Cassandra and Spark. A delegation token is always generated for Spark applications when they are used with Kerberos, and Spark applications are configured to use that token to authenticate the DSEFS client with DSE. DSEFS authentication applies only to communication between the DSEFS client and the DSEFS server. Spark applications Everything that is needed to build your bootstrap Spark Application is supplied by the dse-spark-dependencies dependency. To view the list of all dse-spark-dependencies dependencies, visit our public repo and inspect the pom files that are relevant to your DSE cluster version.

If you connect to any Spark node in a datacenter, DSE will automatically discover the Master address and connect the client to the Master. Specify the URL for any Spark node using the following format:
The DseGraphFrame package provides the Spark base API for bulk operations and analytics on DSE Graph.It is inspired by Databricks’ GraphFrame library and supports a subset of Apache TinkerPop™ Gremlin graph traversal language. It supports reading of DSE Graph data into a GraphFrame and writing GraphFrames from any format supported by Spark into DSE Graph.

Improved Spark Analytic Engine DSE 6 includes a number of improvements “under the hood” to support not just AlwaysOn SQL but also general Spark applications. DataStax has invested in a number of areas to improve the performance of these Spark applications in DSE Analytics. First, DSE 6 upgrades the DSE Analytics engine to Apache Spark 2.2.
of DSE is powerful indexing, search, analytics, and graph functionality, provided by combining Cassandra with Apache Solr, Apache Spark, and DSE Graph. 14 Sep 2018 This Tutorial was created using a DSE 6.0.0 Docker Container, Tableau Desktop 10.5 running on Windows and Spark ODBC driver 1.2.6.1007. 24 May 2015 Extending Analytics with Search: Developers can utilize Solr search syntax in conjunction with Spark's SparkSQL, to extend Spark's analytic 2 Jul 2014 DSE 4.5 introduces an integration with external Hadoop clusters that's important in its own right, but it also provides more options for You do not need to specify the Spark Master address when starting Spark jobs with DSE. If you connect to any Spark node in a datacenter, DSE will automatically discover the Master address and connect the client to the Master. Specify the URL for any Spark node using the following format: DSE Spark nodes use a different resource manager than standalone Spark nodes. The DSE Resource Manager simplifies integration between Spark and DSE. In a DSE Spark cluster, client applications use the CQL protocol to connect to any DSE node, and that node redirects the request to the Spark Master.

Continuous paging streams bulk amounts of records from DSE to the DataStax Java Driver used by DSE Spark. By default, continuous paging in queries is disabled. To enable it, set the spark.dse.continuous_paging_enabled setting to true when starting the Spark SQL shell or in spark-defaults.conf. For example: Spark has proven performance on batch and interactive analytics. Spark also supports streaming from external sources making it a powerful real-time analytics platform. Starting a Spark cluster is as simple as editing one line in the DSE config file or by starting DSE with the `dse cassandra -k` command.
