Sorry, long time no see. We sadly skipped a release on the last month, however, we’ve been back with Droonga 1.0.6 and a great improvement!

What’s Droonga?

Droonga is a distributed full text search engine, compatible to Groonga. A Droonga cluster works like an HTTP server compatible to Groonga with the replication feature.

Droonga became more easy-to-install!

The most important topic on this release Droonga 1.0.6 is the very easy installation. Droonga’s main components, droonga-engine and droonga-http-server are now installable via script for each, so you just run scripts as the root, just like:

# curl https://raw.githubusercontent.com/droonga/droonga-engine/master/install.sh | \
    bash
# curl https://raw.githubusercontent.com/droonga/droonga-http-server/master/install.sh | \
    bash

Then droonga-engine and droonga-http-server are automatically registered as system services managed via the service command. You just have to run simple commands to start/stop services, like:

# service droonga-engine start
# service droonga-http-server start

Moreover, utility commands to manage nodes in the cluster (like droonga-engine-join and droonga-engine-unjoin) also became more easy-to-use. For more details, see the updated “getting started” tutorial and others.

On the other hand, there is a sad news: Droonga’s installation scripts now work only for Debian, Ubuntu, and CentOS 7. Other environments (for example CentOS 6.5, OS X, BSD… and more) are not supported yet. So, if you have knowledges how to install required commands gem, npm (and git) and how to register custom services, please improve the installation script and send pull requests us!

For developers

The installation script works for not only the latest release, but the latest revision of the master branch also. You just have to give an extra environment variable VERSION, like:

# curl https://raw.githubusercontent.com/droonga/droonga-engine/master/install.sh | \
    VERSION=master bash
# curl https://raw.githubusercontent.com/droonga/droonga-http-server/master/install.sh | \
    VERSION=master bash

Then the script tries to install services based on the master. It will help you to try new fixes before the next release.

And, there is a new tutorial to prepare multiple virtual machines on your own PC. It will help you to try Droonga casually.

Detailed list of improvements

• Droonga-engine 1.0.6
  • The installation script is now available. It automatically installs required softwares and configure the droonga-engine as a system service. Currently it works only for Debian, Ubuntu, and CentOS 7.
  • The service works as a process belonging to a user droonga-engine who is specific for the service. The configuration directory for the service is placed under the home directory of the user.
  • A static configuration file to define default parameters (host and so on) is now available. It must be placed into the directory same to catalog.json. You don’t have to run droonga-engine command with many options, anymore.
  • droonga-engine-join now automatically fetches catalog.json from the specified source replica node. Now you don’t have to copy catalog.json from another node before you run droonga-engine-join anymore.
  • A new catalog plugin is introduced as one of default plugins, to fetch catalog.json from existing cluster. The list of plugins in your catalog.json must include it.
  • A new command line utility droonga-engine-configure is available. It generates the static configuration file, the catalog.json for the service. Moreover, it clears old stored data to make the node empty.
  • Some options for utility commands become optional. Important parameters are automatically detected.
  • Restarts server processes more gracefully.
• Droonga-http-server 1.0.7
  • The installation script is now available. It automatically installs required softwares and configure the droonga-http-server as a system service. Currently it works only for Debian, Ubuntu, and CentOS 7.
  • The service works as a process belonging to a user droonga-http-server who is specific for the service. The configuration directory for the service is placed under the home directory of the user.
  • A static configuration file to define default parameters (port and so on) is now available. It must be placed into the configuration directory specified by the environment variable DROONGA_BASE_DIR. You don’t have to run droonga-http-server command with many options, anymore.
  • A new command line utility droonga-http-server-configure is available. It generates the static configuration file for the service.
  • Cached responses are now returned correctly.
• Express-droonga 1.0.5
  • Return cached responses correctly.
• Drntest 1.1.6
  • Sort dump responses for stable test result.
  • Use --ready-notify-fd option to wait droonga-engine is ready.
• Grn2drn 1.0.4
  • Create output directory automatically.
