Scalable, fault-tolerant SQL on FoundationDB

FoundationDB SQL Layer

Overview

The FoundationDB SQL layer is a full SQL implementation that builds on FoundationDB’s core features. It gets the same high performance, multi-node scalability, fault-tolerance, and true multi-key ACID transactions while also providing new capabilities, including a sophisticated SQL environment and direct object access.

It was written from the ground up in Java and utilizes the FoundationDB SQL Parser.

Check out https://foundationdb.com/layers/sql for the full documentation.

Prerequisites

The FoundationDB SQL Layer requires Java 7 Runtime Environment and FoundationDB.

JRE

The FoundationDB SQL Layer requires the Java 7 Runtime Environment (JRE). Both OpenJDK JRE and the official Oracle JRE are supported.

See the Oracle Java SE Downloads page for installation details.

FoundationDB

To install FoundationDB, follow the official Getting Started guides, being sure to check that the cluster is up and running (covered in Testing your FoundationDB installation).

Installing the SQL Layer

The SQL Layer can be installed from system packages (appropriate for most people) or directly from source (intended for developers).

a. Packages

Official packages for Windows, OS X, Ubuntu and CentOS/RedHat are available. See the installation section for more details.

A single instance of the SQL Layer is installed by default and is appropriate for local development. Consult the documentation for recommended multi-node configurations.

b. Source

Note: This section is intended only for developers.

Use Maven to build the project:

$ mvn package

All unit and integration tests will be run by default, which could be lengthy. Test execution can be avoided with the skipTests option:

$ mvn package -DskipTests=true

An executable jar, and required dependencies, will be the target/ directory once packaging is complete.

The server can then be started with the fdbsqllayer script. The -f flag will run it in the foreground:

$ ./bin/fdbsqllayer -f

A handful of informational messages will print and then the server will state it is ready:

2013-03-22 15:36:29,561 [main] INFO  ServiceManager - FoundationDB SQL Layer ready.

When installing from source, you'll also want the SQL Layer Client Tools.

5. Testing Your SQL Layer Installation

The SQL Layer can then be accessed using the SQL client on port 15432:

$ fdbsqlcli -c 'SELECT VERSION();'
        _SQL_COL_1         
--------------------------
 FoundationDB x.y.z +hash 
(1 row)

And using a RESTful API on port 8091:

$ curl http://localhost:8091/v1/version
[
{"server_name":"FoundationDB SQL Layer","server_version":"x.y.z+hash"}
]
