ASTERIXDB-1415 Fix Feed Freeze with Indexed Dataset

A feed might cause the system to freeze when connected to
a dataset that has secondary indexes. This case happen if
a frame contains all duplicate records pass the primary index
insert operator. The root cause is that the assign runtime in
the pipeline assumes at least a single record. Hence, a corrupted
tuple will reach the commit operator which will create a bad log
record with a PK of size 0. The log record will cause the log
flusher thread to die.

#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 8 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.

Instructions for building the master:

  • Checkout AsterixDB master:

      $git clone https://github.com/apache/incubator-asterixdb.git

  • Build AsterixDB master:

      $cd incubator-asterixdb
  $mvn clean package -DskipTests

##Running AsterixDB (on your machine from your build) Here are steps to get AsterixDB running on your machine:

  • Create a directory as the home for AsterixDB installer program, i.e., managix:

      $mkdir ~/managix

  • Copy AsterixDB binary artifact into the installer directory and unzip it:

      $cp asterixdb/asterix-installer/target/asterix-installer-*-binary-assembly.zip ~/managix/
  $cd ~/managix
  $unzip asterix-installer-*-binary-assembly.zip

  • Configure the installer:

      $bin/managix configure

  • Validate if the computer environment is suitable:

      $bin/managix validate

  • Create and start your instance:

      $bin/managix create -n test -c clusters/local/local.xml

  • Good to go and run queries in your browser at:

      http://localhost:19001

  • Read more documentations to learn the data model, query language, and how to create a cluster instance: [https://ci.apache.org/projects/asterixdb/index.html] (https://ci.apache.org/projects/asterixdb/index.html)

##Documentation

AsterixDB's official documentation resides at [https://ci.apache.org/projects/asterixdb/index.html] (https://ci.apache.org/projects/asterixdb/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 build version, so for pre-release versions one should refer to the compiled documentation.
