201 <h1>AsterixDB</h1>
202<p>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:</p>
203
204<ul>
205
206<li>A semistructured NoSQL style data model (ADM) resulting from extending JSON with object database ideas</li>
207
208<li>An expressive and declarative query language (AQL) that supports a broad range of queries and analysis over semistructured data</li>
209
210<li>A parallel runtime query execution engine, Hyracks, that has been scale-tested on up to 1000+ cores and 500+ disks</li>
211
212<li>Partitioned LSM-based data storage and indexing to support efficient ingestion and management of semistructured data</li>
213
214<li>Support for query access to externally stored data (e.g., data in HDFS) as well as to data stored natively by AsterixDB</li>
215
216<li>A rich set of primitive data types, including spatial and temporal data in addition to integer, floating point, and textual data</li>
217
218<li>Secondary indexing options that include B+ trees, R trees, and inverted keyword (exact and fuzzy) index types</li>
219
220<li>Support for fuzzy and spatial queries as well as for more traditional parametric queries</li>
221
222<li>Basic transactional (concurrency and recovery) capabilities akin to those of a NoSQL store</li>
223</ul>

226<h3>Disclaimer<a name="Disclaimer"></a></h3>
227<p>Apache AsterixDB is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</p></div></div>
