ASTERIXDB-976: CSV support for all basic types Implements date/time, spatial, UUID, and hexbinary types for CSV output. Spatial output is "best we can do" - a double-quoted string containing the "clean JSON" representation of the value. Interval remains unsupported. Also fixes a few import errors in the clean JSON implementation.

#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:

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

##Building AsterixDB

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 3.1.1 or newer.
Java 7 or newer.

Additionally to run all the integration tests you should be running sshd locally, and have passwordless ssh logins enabled for the account which is running the tests.

##Documentation

AsterixDB's official documentation resides at [http://asterixdb.ics.uci.edu/documentation/index.html] (http://asterixdb.ics.uci.edu/documentation/index.html). This is built from the maven project under asterix-doc/ as a maven site. The documentation on the official website refers to the most stable release version, so for pre-release versions one should refer to the compiled documentation.
