AsterixDB is a BDMS (Big Data Management System) with a rich feature set that sets it apart from other Big Data platforms. Its feature set makes it well-suited to modern needs such as web data warehousing and social data storage and analysis. AsterixDB has: - __Data model__<br/> A semistructured NoSQL style data model ([ADM](https://ci.apache.org/projects/asterixdb/datamodel.html)) resulting from extending JSON with object database ideas - __Query languages__<br/> An expressive and declarative query language ([SQL++](http://asterixdb.apache.org/docs/0.9.7/sqlpp/manual.html) that supports a broad range of queries and analysis over semistructured data - __Scalability__<br/> A parallel runtime query execution engine, Apache Hyracks, that has been scale-tested on up to 1000+ cores and 500+ disks - __Native storage__<br/> Partitioned LSM-based data storage and indexing to support efficient ingestion and management of semistructured data - __External storage__<br/> Support for query access to externally stored data (e.g., data in HDFS) as well as to data stored natively by AsterixDB - __Data types__<br/> A rich set of primitive data types, including spatial and temporal data in addition to integer, floating point, and textual data - __Indexing__<br/> Secondary indexing options that include B+ trees, R trees, and inverted keyword (exact and fuzzy) index types - __Transactions__<br/> Basic transactional (concurrency and recovery) capabilities akin to those of a NoSQL store Learn more about AsterixDB at its [website](http://asterixdb.apache.org). ## Build from source To build AsterixDB from source, you should have a platform with the following: * A Unix-ish environment (Linux, OS X, will all do). * git * Maven 3.3.9 or newer. * JDK 11 or newer. * Python 3.6+ with pip and venv Instructions for building the master: * Checkout AsterixDB master: $git clone https://github.com/apache/asterixdb.git * Build AsterixDB master: $cd asterixdb $mvn clean package -DskipTests ## Run the build on your machine Here are steps to get AsterixDB running on your local machine: * Start a single-machine AsterixDB instance: $cd asterixdb/asterix-server/target/asterix-server-*-binary-assembly/apache-asterixdb-*-SNAPSHOT $./opt/local/bin/start-sample-cluster.sh * Good to go and run queries in your browser at: http://localhost:19006 * Read more [documentation](https://ci.apache.org/projects/asterixdb/index.html) to learn the data model, query language, and how to create a cluster instance. ## Documentation To generate the documentation, run asterix-doc with the generate.rr profile in maven, e.g `mvn -Pgenerate.rr ...` Be sure to run `mvn package` beforehand or run `mvn site` in asterix-lang-sqlpp to generate some resources that are used in the documentation that are generated directly from the grammar. * [master](https://ci.apache.org/projects/asterixdb/index.html) | [0.9.7](http://asterixdb.apache.org/docs/0.9.7/index.html) | [0.9.6](http://asterixdb.apache.org/docs/0.9.6/index.html) | [0.9.5](http://asterixdb.apache.org/docs/0.9.5/index.html) | [0.9.4.1](http://asterixdb.apache.org/docs/0.9.4.1/index.html) | [0.9.4](http://asterixdb.apache.org/docs/0.9.4/index.html) | [0.9.3](http://asterixdb.apache.org/docs/0.9.3/index.html) | [0.9.2](http://asterixdb.apache.org/docs/0.9.2/index.html) | [0.9.1](http://asterixdb.apache.org/docs/0.9.1/index.html) | [0.9.0](http://asterixdb.apache.org/docs/0.9.0/index.html) ## Community support - __Users__</br> maling list: [[email protected]](mailto:[email protected])</br> Join the list by sending an email to [[email protected]](mailto:[email protected])</br> - __Developers and contributors__</br> mailing list:[[email protected]](mailto:[email protected])</br> Join the list by sending an email to [[email protected]](mailto:[email protected])
