Aerospike Database Server

Welcome to the Aerospike Database Server source code tree!

Aerospike is a distributed, scalable NoSQL database. It is architected with three key objectives:

• To create a high-performance, scalable platform that would meet the needs of today's web-scale applications
• To provide the robustness and reliability (i.e., ACID) expected from traditional databases.
• To provide operational efficiency (minimal manual involvement)

Telemetry Anonymized Data Collection

The Aerospike Community Edition collects anonymized server performance statistics. Please see the Aerospike Telemetery web page for more information. The full Telemetry data collection agent source code may be found in the "telemetry" submodule.

Build Prerequisites

The Aerospike Database Server can be built and deployed on various current 64-bit GNU/Linux platform versions, such as the Red Hat family (e.g., CentOS 6 or later), Debian 7 or later, and Ubuntu 10.04 or later.

Dependencies

The majority of the Aerospike source code is written in the C programming language, conforming to the ANSI C99 standard.

In particular, the following tools and libraries are needed:

C Compiler Toolchain

Building Aerospike requires the GCC 4.1 or later C compiler toolchain, with the standard GNU/Linux development tools and libraries installed in the build environment, including:

• autoconf

• automake

• libtool

• make

C++

The C++ compiler is required for the Aerospike geospatial indexing feature and its dependency, Google's S2 Geometry Library (both written in C++.)

• The required CentOS 6/7 package to install is: gcc-c++.

• The required Debian 7/8 and Ubuntu 10/12/14/16 package to install is: g++.

OpenSSL

OpenSSL 0.9.8b or later is required for cryptographic hash functions (RIPEMD-160 & SHA-1) and pseudo-random number generation.

• The CentOS 6/7 OpenSSL packages to install are: openssl, openssl-devel, openssl-static.

• The Debian 7/8 and Ubuntu 10/12/14/16 OpenSSL packages to install are: openssl and libssl-dev.

Lua 5.1

The Lua 5.1 language is required for User Defined Function (UDF) support.

• By default, Aerospike builds with Lua 5.1 support provided by the LuaJIT submodule.

• Alternatively, it is possible to build with standard Lua 5.1 provided by the build environment. In that case:

  • The CentOS 6/7 Lua packages to install are: lua, lua-devel, and lua-static.

  • The Debian 7/8 and Ubuntu 10/12/14/16 Lua packages to install are: lua5.1 and liblua5.1-dev.

  • Build by passing the USE_LUAJIT=0 option to make.

Python 2

Running the Telemetry Agent requires Python 2.6+, which is available by default on most platforms, and can be installed on Ubuntu 16.04 as the package python.

Submodules

The Aerospike Database Server build depends upon 8 submodules:

Submodule	Description
common	The Aerospike Common Library
jansson	C library for encoding, decoding and manipulating JSON data
jemalloc	The JEMalloc Memory Allocator
lua-core	The Aerospike Core Lua Source Files
luajit	The LuaJIT (Just-In-Time Compiler for Lua)
mod-lua	The Aerospike Lua Interface
s2-geometry-library	The S2 Spherical Geometry Library
telemetry	The Aerospike Telemetry Agent (Community Edition only)

After the initial cloning of the aerospike-server repo., the submodules must be fetched for the first time using the following command:

$ git submodule update --init

Note: As this project uses submodules, the source archive downloadable via GitHub's Download ZIP button will not build unless the correct revision of each submodule is first manually installed in the appropriate modules subdirectory.

Building Aerospike

Default Build

$ make          -- Perform the default build (no packaging.)

Note: You can use the -j option with make to speed up the build on multiple CPU cores. For example, to run four parallel jobs:

$ make -j4

Build Options

$ make deb      -- Build the Debian (Ubuntu) package.

$ make rpm      -- Build the Red Hat Package Manager (RPM) package.

$ make tar      -- Build the "Every Linux" compressed "tar" archive (".tgz") package.

$ make source   -- Package the source code as a compressed "tar" archive.

$ make clean    -- Delete any existing build products, excluding built packages.

$ make cleanpkg -- Delete built packages.

$ make cleanall -- Delete all existing build products, including built packages.

$ make cleangit -- Delete all files untracked by Git.  (Use with caution!)

$ make strip    -- Build "strip(1)"ed versions of the server executables.

Overriding Default Build Options

$ make {<Target>}* {<VARIABLE>=<VALUE>}*  -- Build <Target>(s) with optional variable overrides.

Example:

$ make USE_JEM=0   -- Default build *without* JEMalloc support.

Configuring Aerospike

Sample Aerospike configuration files are provided in as/etc. The developer configuration file, aerospike_dev.conf, contains basic settings that should work out-of-the-box on most systems. The package example configuration files, aerospike.conf, and the Solid State Drive (SSD) version, aerospike_ssd.conf, are suitable for running Aerospike as a system daemon.

These sample files may be modified for specific use cases (e.g., setting network addresses, defining namespaces, and setting storage engine properties) and tuned for for maximum performance on a particular system. Also, system resource limits may need to be increased to allow, e.g., a greater number of concurrent connections to the database. See "man limits.conf" for how to change the system's limit on a process' number of open file descriptors ("nofile".)

Running Aerospike

There are several options for running the Aerospike database. Which option to use depends upon whether the primary purpose is production deployment or software development.

The preferred method for running Aerospike in a production environment is to build and install the Aerospike package appropriate for the target Linux distribution (i.e., an ".rpm", ".deb", or ".tgz" file), and then to control the state of the Aerospike daemon, either via the SysV daemon init script commands, e.g., service aerospike start, or else via systemctl on systemd-based systems, e.g., systemctl start aerospike.

A convenient way to run Aerospike in a development environment is to use the following commands from within the top-level directory of the source code tree (aerospike-server):

To create and initialize the run directory with the files needed for running Aerospike, use:

$ make init

or, equivalently:

$ mkdir -p run/{log,work/{smd,{sys,usr}/udf/lua}}
$ cp -pr modules/lua-core/src/* run/work/sys/udf/lua

To launch the server with as/etc/aerospike_dev.conf as the config:

$ make start

or, equivalently:

$ nohup ./modules/telemetry/telemetry.py as/etc/telemetry_dev.conf > /dev/null 2>&1 &
$ target/Linux-x86_64/bin/asd --config-file as/etc/aerospike_dev.conf

To halt the server:

$ make stop

or, equivalently:

$ PID=`pgrep telemetry.py | grep -v grep`; if [ -n "$PID" ]; then kill $PID; fi
$ kill `cat run/asd.pid` ; rm run/asd.pid
