| <h1>AsterixDB</h1> |
| <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> |
| <ul> |
| |
| <li> |
| |
| <p><b>Data model</b><br /> A semistructured NoSQL style data model (<a href="datamodel.html">ADM</a>) resulting from extending JSON with object database ideas</p> |
| </li> |
| <li> |
| |
| <p><b>Query languages</b><br /> Two expressive and declarative query languages (<a href="sqlpp/manual.html">SQL++</a> and <a href="aql/manual.html">AQL</a>) that support a broad range of queries and analysis over semistructured data</p> |
| </li> |
| <li> |
| |
| <p><b>Scalability</b><br /> A parallel runtime query execution engine, Apache Hyracks, that has been scale-tested on up to 1000+ cores and 500+ disks</p> |
| </li> |
| <li> |
| |
| <p><b>Native storage</b><br /> Partitioned LSM-based data storage and indexing to support efficient ingestion and management of semistructured data</p> |
| </li> |
| <li> |
| |
| <p><b>External storage</b><br /> Support for query access to externally stored data (e.g., data in HDFS) as well as to data stored natively by AsterixDB</p> |
| </li> |
| <li> |
| |
| <p><b>Data types</b><br /> A rich set of primitive data types, including spatial and temporal data in addition to integer, floating point, and textual data</p> |
| </li> |
| <li> |
| |
| <p><b>Indexing</b><br /> Secondary indexing options that include B+ trees, R trees, and inverted keyword (exact and fuzzy) index types</p> |
| </li> |
| <li> |
| |
| <p><b>Transactions</b><br /> Basic transactional (concurrency and recovery) capabilities akin to those of a NoSQL store</p> |
| </li> |
| </ul> |
