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