The data sources that Drill supports include file systems (local or distributed) and HBase. Drill also integrates with the Hive metastore seamlessly to complement existing Hive environments with low latency queries. Unlike traditional RDBMS or SQL-on-Hadoop solutions that require centralized schema definitions, Drill can query self-describing data as well as complex or multi-structured data that is commonly seen in big data systems. Moreover, Drill does not require a fully structured schema and can support semi-structured or nested data types such as JSON. Apache Drill processes the data in record batches and discovers the schema during the processing of each record batch. Thus, Drill has the capability to support changing schemas over the lifetime of a query. Drill reconfigures its operators and handles these situations to make sure that data is not lost. Apache Drill can support multiple Hive, HBase, and DFS data sources, including CSV, TSV, Parquet, and JSON files. Connections between data sources and Drill can be configured through Drill’s web UI. Note: For information about connecting Apache Drill to data sources, see the Apache Drill documentation: http://drill.apache.org/docs/. About the Driver The Simba Drill JDBC Driver lets organizations connect their BI tools to Drill. Drill provides an ANSI SQL query layer and also exposes the metadata information through an ANSI SQL standard metadata database called INFORMATION_SCHEMA. The Simba Drill JDBC Driver leverages INFORMATION_SCHEMA to expose Drill's metadata to BI tools as needed. The Simba Drill JDBC Driver complies with the JDBC 4.0 and 4.1 data standards. JDBC is one of the most established and widely supported APIs for connecting to and working with databases. At the heart of the technology is the JDBC driver, which connects an application to the database. For more information about JDBC, see Data www.simba.com 6 Installation and Configuration Guide About the Simba Drill JDBC Driver Access Standards on the Simba Technologies website: https://www.simba.com/resources/data-access-standards-glossary. This guide is suitable for users who want to access data residing within Drill from their desktop environment. Application developers might also find the information helpful. Refer to your application for details on connecting via JDBC. www.simba.com 7 Installation and Configuration Guide System Requirements System Requirements Each machine where you use the Simba Drill JDBC Driver must have Java Runtime Environment (JRE) 8.0 installed. www.simba.com 8 Installation and Configuration Guide Simba Drill JDBC Driver Files Simba Drill JDBC Driver Files The Simba Drill JDBC Driver is delivered in a ZIP archive named DrillJDBC41- [Version].zip, where [Version] is the version number of the driver. The archive contains the driver supporting the JDBC API version indicated in the archive name, as well as release notes and third-party license information. In addition, the required third-party libraries and dependencies are packaged and shared in the driver JAR file in the archive. www.simba.com 9 Installation and Configuration Guide Installing and Using the Simba Drill JDBC Driver Installing and Using the Simba Drill JDBC Driver To install the Simba Drill JDBC Driver on your machine, extract the files from the ZIP archive to the directory of your choice. Important: If you received a license file through email, then you must copy the file into the same directory as the driver JAR file before you can use the Simba Drill JDBC Driver. To access a Drill data store using the Simba Drill JDBC Driver, you need to configure the following: l The list of driver library files (see Referencing the JDBC Driver Libraries on page 10) l The Driver or DataSource class (see Registering the Driver Class on page 11) l The connection URL for the driver (see Building the Connection URL on page 12 ) Important: The Simba Drill JDBC Driver provides read-only access to Drill data stores. Referencing the JDBC Driver Libraries Before you use the Simba Drill JDBC Driver, the JDBC application or Java code that you are using to connect to your data must be able to access the driver JAR files. In the application or code, specify all the JAR files that you extracted from the ZIP archive. Using the Driver in a JDBC Application Most JDBC applications provide a set of configuration options for adding a list of driver library files. Use the provided options to include all the JAR files from the ZIP archive as part of the driver configuration in the application. For more information, see the documentation for your JDBC application. Using the Driver in Java Code You must include all the driver library files in the class path. This is the path that the Java Runtime Environment searches for classes and other resource files.

  • A Comprehensive Study of Bloated Dependencies in the Maven Ecosystem
    Noname manuscript No. (will be inserted by the editor) A Comprehensive Study of Bloated Dependencies in the Maven Ecosystem César Soto-Valero · Nicolas Harrand · Martin Monperrus · Benoit Baudry Received: date / Accepted: date Abstract Build automation tools and package managers have a profound influence on software development. They facilitate the reuse of third-party libraries, support a clear separation between the application’s code and its ex- ternal dependencies, and automate several software development tasks. How- ever, the wide adoption of these tools introduces new challenges related to dependency management. In this paper, we propose an original study of one such challenge: the emergence of bloated dependencies. Bloated dependencies are libraries that the build tool packages with the application’s compiled code but that are actually not necessary to build and run the application. This phenomenon artificially grows the size of the built binary and increases maintenance effort. We propose a tool, called DepClean, to analyze the presence of bloated dependencies in Maven artifacts. We ana- lyze 9; 639 Java artifacts hosted on Maven Central, which include a total of 723; 444 dependency relationships. Our key result is that 75:1% of the analyzed dependency relationships are bloated. In other words, it is feasible to reduce the number of dependencies of Maven artifacts up to 1=4 of its current count. We also perform a qualitative study with 30 notable open-source projects. Our results indicate that developers pay attention to their dependencies and are willing to remove bloated dependencies: 18/21 answered pull requests were accepted and merged by developers, removing 131 dependencies in total.

As it is with the core Hadoop stack, Drill is also highly customizable, with plenty of performance tuning parame- ters to ensure optimal efficiency. Tweaking these parameters however, requires deep domain knowledge and technical insight, and even then the optimal con- figuration may not be evident. Businesses will want to use Apache Drill in a Hadoop cluster, without the hassle of configuring it, for the most cost-effective implementation. This can be done by solving the following problems: • How to apply evolutionary algorithms to automatically tune a distributed Apache Drill configuration, regardless of cluster environment.

The need to store and manipulate large volume of (unstructured) data has led to the development of several NoSQL databases for better scalability. Graph databases are a particular kind of NoSQL databases that have proven their efficiency to store and query highly interconnected data, and have become a promising solution for multiple applications. While the mapping of conceptual schemas to relational databases is a well-studied field of research, there are only few solutions that target conceptual modeling for NoSQL databases and even less focusing on graph databases.
