[NO ISSUE][COMP] Add sanity checks to the optimizer Details: - Introduce sanity checking code in the optimizer that runs before and after each rule (when enabled) - PlanStructureVerifier runs after each fired rule and checks that there are no shared references/instances in the plan - PlanStabilityVerifier runs after each failed rule and checks that the rule did not make any changes in the plan - Add new compiler property "compiler.internal.sanitycheck" which controls whether the above sanity checks are performed during query compilation. It's default value is 'false', so sanity checks are disabled - Modify testsuite configuration to enable these sanity checks - Remove ConstantExpression.setValue() - Add IPlanPrettyPrinter.printExpression() Change-Id: I4e53f57dd6263d3b292700490d9e57f5cd48cc19 Reviewed-on: https://asterix-gerrit.ics.uci.edu/c/asterixdb/+/7407 Integration-Tests: Jenkins <jenkins@fulliautomatix.ics.uci.edu> Tested-by: Jenkins <jenkins@fulliautomatix.ics.uci.edu> Reviewed-by: Dmitry Lychagin <dmitry.lychagin@couchbase.com> Reviewed-by: Ali Alsuliman <ali.al.solaiman@gmail.com>
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:
Data model
A semistructured NoSQL style data model (ADM) resulting from extending JSON with object database ideas
Query languages
Two expressive and declarative query languages (SQL++ and AQL) that support a broad range of queries and analysis over semistructured data
Scalability
A parallel runtime query execution engine, Apache Hyracks, that has been scale-tested on up to 1000+ cores and 500+ disks
Native storage
Partitioned LSM-based data storage and indexing to support efficient ingestion and management of semistructured data
External storage
Support for query access to externally stored data (e.g., data in HDFS) as well as to data stored natively by AsterixDB
Data types
A rich set of primitive data types, including spatial and temporal data in addition to integer, floating point, and textual data
Indexing
Secondary indexing options that include B+ trees, R trees, and inverted keyword (exact and fuzzy) index types
Transactions
Basic transactional (concurrency and recovery) capabilities akin to those of a NoSQL store

To build AsterixDB from source, you should have a platform with the following:
Instructions for building the master:
Checkout AsterixDB master:
$git clone https://github.com/apache/asterixdb.git
Build AsterixDB master:
$cd asterixdb $mvn clean package -DskipTests
Here are steps to get AsterixDB running on your local machine:
Start a single-machine AsterixDB instance:
$cd asterixdb/asterix-server/target/asterix-server-*-binary-assembly/apache-asterixdb-*-SNAPSHOT $./opt/local/bin/start-sample-cluster.sh
Good to go and run queries in your browser at:
http://localhost:19006
