Enabling SSL for the Spark SQL Thrift ServerĬommunication with the Spark SQL Thrift Server can be encrypted using SSL. The Spark SQL Thrift server uses a JDBC and an ODBC interface for client connections to DSE. The Spark DataFrame API encapsulates data sources, including DataStax Enterprise data, organized into named columns. Spark SQL supports queries that are written using HiveQL, a SQL-like language that produces queries that are converted to Spark jobs. Static columns are mapped to different columns in Spark SQL and require special handling. Inserting data into tables with static columns using Spark SQL. Spark SQL supports a subset of the SQL-92 language. Spark SQL can query DSE Graph vertex and edge tables. Querying DSE Graph vertices and edges with Spark SQL. Java applications that query table data using Spark SQL require a Spark session instance. You can execute Spark SQL queries in Java applications that traverse over tables. Querying database data using Spark SQL in Java. When you start Spark, DataStax Enterprise creates a Spark session instance to allow you to run Spark SQL queries against database tables. You can execute Spark SQL queries in Scala by starting the Spark shell. Querying database data using Spark SQL in Scala. Spark SQL allows you to execute Spark queries using a variation of the SQL language. This data can then be analyzed by Spark applications, and the data can be stored in the database. Spark Streaming allows you to consume live data streams from sources, including Akka, Kafka, and Twitter. Spark Streaming, Spark SQL, and MLlib are modules that extend the capabilities of Spark. Using Spark modules with DataStax Enterprise. Information about Spark architecture and capabilities.ĭataStax Enterprise integrates with Apache Spark to allow distributed analytic applications to run using database data.Ĭonfiguring Spark includes setting Spark properties for DataStax Enterprise and the database, enabling Spark apps, and setting permissions. Spark is the default mode when you start an analytics node in a packaged installation. 
Guidelines and steps to set the replication factor for keyspaces on DSE Analytics nodes.ĭSE SearchAnalytics clusters can use DSE Search queries within DSE Analytics jobs.ĭSE Analytics Solo datacenters provide analytics processing with Spark and distributed storage using DSEFS without storing transactional database data. Setting the replication factor for analytics keyspaces.DSE Analytics includes integration with Apache Spark. Use DSE Analytics to analyze huge databases. 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.ĭataStax Enterprise 5.1 Analytics includes integration with Apache Spark. Initializing a DataStax Enterprise cluster includes configuring, and choosing how the data is divided across the nodes in the cluster. 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.
