Vespa

Vespa is an engine for low-latency computation over large data sets. It stores and indexes your data such that queries, selection and processing over the data can be performed at serving time.

This README describes how to build and develop the Vespa engine. To get started, read the quick start, or find the full documentation at http://docs.vespa.ai/.

Get started developing

Setup build environment

C++ building is supported on CentOS 7. The Java source can be built on any platform having Java 8 and Maven installed. We recommend using the following environment: Create C++ dev environment on CentOS using VirtualBox and Vagrant. You can also setup CentOS 7 natively and install the following build dependencies:

sudo yum-config-manager --add-repo https://copr.fedorainfracloud.org/coprs/g/vespa/vespa/repo/epel-7/group_vespa-vespa-epel-7.repo
sudo yum -y install epel-release centos-release-scl yum-utils
sudo yum -y install ccache \
    rpm-build
yum-builddep -y <vespa-source>/dist/vespa.spec

Build Java modules

export MAVEN_OPTS="-Xms128m -Xmx512m"
sh bootstrap.sh java
mvn -T <num-threads> install

Build C++ modules

Replace <build-dir> with the name of the directory in which you'd like to build Vespa. Replace <source-dir> with the directory in which you've cloned/unpacked the source tree.

sh bootstrap-cpp.sh <source-dir> <build-dir>
cd <build-dir>
make -j <num-threads>
ctest3 -j <num-threads>

Create RPM packages

sh dist.sh VERSION && rpmbuild -ba ~/rpmbuild/SPECS/vespa-VERSION.spec

Run Vespa on a local machine

A basic, single-node install is found in the quick start. For multi-node and using Node Admin, read node-admin/README.md.
