"Apache Drill: Tracking its history as an open source community". ![]() The dashboard library, Apache Superset, is particularly well suited for visualization of data queried with Drill. The default install includes a web interface allowing end-users to execute ANSI SQL directly and export data tables as CSV files without any programming. Front-end Support ĭrill itself can be queried via JDBC, ODBC, or REST through a variety of methods and languages including Python and Java. Drill's "schema-free" JSON data model enables it to query non-relational datastores in-situ. RDBMs storage plugins (Using JDBC to connect to MySQL, PostgreSQL, and others)Ī new datastore can be added by developing a storage plugin.Diverse data formats, including Apache Avro, Apache Parquet and JSON.Cloud storage: Amazon S3, Google Cloud Storage, Azure Blob Storage, Swift, IBM Cloud Object Storage.Online Analytical Processing: Apache Kudu, Apache Druid, OpenTSDB.NoSQL: MongoDB, Apache HBase, Apache Cassandra.All Hadoop distributions (HDFS API 2.3+), including Apache Hadoop, MapR, CDH and Amazon EMR.Some additional datastores that it supports include: A notable feature also includes in situ querying of local JSON and Apache Parquet files. Apache Drill 1.11 added cryptographic-related functions and PCAP file format support.ĭrill is primarily focused on non-relational datastores, including Apache Hadoop text files, NoSQL, and cloud storage.Apache Drill 1.9 added dynamic user defined functions.Pluggable architecture enables connectivity to multiple datastores.Industry-standard APIs: ANSI SQL, ODBC/JDBC, RESTful APIs.Schema-free JSON document model similar to MongoDB and Elasticsearch, without requiring a formal schema to be declared.One explicitly stated design goal is that Drill is able to scale to 10,000 servers or more and to be able to process petabytes of data and trillions of records in seconds. In addition, Drill supports data locality, if Drill and the datastore are on the same nodes. For example, you can join a user profile collection in MongoDB with a directory of event logs in Hadoop.ĭrill's datastore-aware optimizer automatically restructures a query plan to leverage the datastore's internal processing capabilities. A single query can join data from multiple datastores. ĭrill supports a variety of NoSQL databases and file systems, including Alluxio, HBase, MongoDB, MapR-DB, HDFS, MapR-FS, Amazon S3, Azure Blob Storage, Google Cloud Storage, Swift, NAS and local files. It was designated an Apache Software Foundation top-level project in December 2016. Tom Shiran is the founder of the Apache Drill Project. Built chiefly by contributions from developers from MapR, Drill is inspired by Google's Dremel system, also productized as BigQuery. Apache Drill is an open-source software framework that supports data-intensive distributed applications for interactive analysis of large-scale datasets.
