What is AsterixDB?
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 
 A semistructured NoSQL style data model (ADM) resulting from extending JSON with object database ideas
-  Query languages 
 Two expressive and declarative query languages (SQL++ and AQL) that support a broad range of queries and analysis over semistructured data
-  Scalability 
 A parallel runtime query execution engine, Apache Hyracks, that has been scale-tested on up to 1000+ cores and 500+ disks
-  Native storage 
 Partitioned LSM-based data storage and indexing to support efficient ingestion and management of semistructured data
-  External storage 
 Support for query access to externally stored data (e.g., data in HDFS) as well as to data stored natively by AsterixDB
-  Data types 
 A rich set of primitive data types, including spatial and temporal data in addition to integer, floating point, and textual data
-  Indexing 
 Secondary indexing options that include B+ trees, R trees, and inverted keyword (exact and fuzzy) index types
-  Transactions 
 Basic transactional (concurrency and recovery) capabilities akin to those of a NoSQL store

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 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.
