Gluent continues to enhance the Data Platform products with each release and with version 3.1 we bring additional ease of use to the data management tools. Gluent has moved to a pluggable architecture allowing us to add support for almost any SQL Engine. This release adds support for Spark SQL.
A number of reporting improvements have been made to Gluent Advisor Portal to provide a bird’s eye view of database offloadability. The 3.1 release also builds on the support for Amazon EMR and S3 (added in 3.0) and includes many other functional, operational and performance improvements. Security considerations continue to be at the forefront of all of Gluent’s products and new security options have been added in the 3.1 release, together with a new Security guide.
Greater Flexibility with Query Engines
Prior to the 3.1 release, a single SQL-on-Hadoop engine was used for all Gluent operations, whether related to orchestration (Offload/Present) or transparent queries (end-user queries that invoke Smart Connector). However, a single SQL engine might not be suited to all user query workloads, therefore Smart Connector has been re-architected to allow end-users to select a SQL engine to use for transparent queries and no longer be restricted to the engine chosen for Gluent orchestration activities. As of Gluent’s 3.1 release, users can choose between Impala, Hive, Hive (LLAP) and Spark, depending on the Hadoop distribution.
Gluent’s 3.1 release introduces a new offload transport engine, utilizing Spark, to be used as a configurable alternative to Sqoop. Gluent’s offload product continues to support Sqoop as an industry-recognized data transport engine, but users can now select the Spark-based offload transport engine as a high-performance alternative, supporting greater concurrency. By utilizing Spark for offload transport, Gluent has reduced the time it takes to offload data at all volumes, with considerable time savings in process startup and the data transport itself.
Smart Connector introduces support for Spark SQL
One of the key benefits of the re-architecture of Smart Connector in the 3.1 release is that support for new SQL engines can be easily “plugged in”, thereby enabling Gluent to provide customers with a larger range of SQL engines in fewer releases. The first additional query engine to be added to Smart Connector is Spark SQL.
Gluent Advisor Portal Improves Usability with Pre-Configured Reports
Gluent Advisor Portal was released in 3.0 and provides customers with a simple-to-use web application for generating, viewing and downloading rich HTML Advisor reports. The 3.1 release further improves the usability of Gluent Advisor Portal by highlighting key statistics and metrics to provide an instant and comparable view of each database’s offload potential. A new set of pre-configured reports further summarize the findings of each Advisor report in tabular form, providing a simple view of offloadability, database size, database environment and Advisor parameters. This summary data complements the drill-down information presented in the Advisor report itself.
Functional and Performance Improvements Provide Better Control
Gluent’s 3.1 release continues to deliver functional improvements across the product set. For example, diagnose now supports the collection of Hive and Spark diagnostic information in addition to Impala. Gluent’s multitenancy feature now caters fully for tables offloaded from multitenant Oracle databases and Offload/Present both support the Amazon EMR S3 driver for data stored on Amazon S3 storage accessed through EMR.
Operational improvements continue to be provided with each Gluent release. For example, many new checks have been added to our Connect utility to validate the configuration of Gluent software. In addition, the 3.1 release certifies Gluent’s products on SLES-based systems.
As with previous releases, the 3.1 release includes several performance improvements. For example, Join Filter Pulldown (JFPD) has been improved to cater for more complex query execution plans and predicate optimizations. The performance of SQLMon has been improved, particularly for large, complex SQL statements and as described earlier, the new Spark-based offload transport enables data to be offloaded faster and with greater concurrency.
Security continues to be at the forefront of all Gluent software and the 3.1 release continues to harden the product set. For example, support has been added for Oracle Wallet authentication during offload transport and Gluent’s Result Cache architecture now supports Hadoop Secure Mode.
