Adapt Replication to Append Only LSM Components

This change includes the following:
- Make LSN recording in a single tree in LSM components.
- Pass LSN byte offset with every tree index file being replicated.
- Add LSN to remote recovery logs to check which logs should be replayed.
- Update ILogRecord method names to better describe their operation.

#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.
