Thank you for your entry to our conference “Groonga Night 5th” at 2014-11-29!

Droonga 1.0.9 is an extra release. On the session at the conference, we have some troubles. Those issues have been fixed at this release!

Improvements of Droonga 1.0.9

First, now droonga-engine-join, droonga-engine-unjoin, and droonga-engine-absorb-data are runnable on any node. In old versions, those commands had some elusive preconditions, so they were inconvenience a little.

Second, unjoined nodes are correctly invisible from droonga-http-servers. At the previous version, droonga-http-server unexpectedly kept connections to droonga-engine nodes even if they were already unjoined from the cluster. Now droonga-engine nodes manage their relations by unique id for each Droonga cluster, and droonga-http-server can detect which engine node was unjoined by the cluster’s id.

These fixes will let you more easy to try Droonga!

Detailed list of improvements

• Droonga-engine 1.0.9
  • droonga-engine-join, droonga-engine-unjoin, and droonga-engine-absorb-data work on any host. Instead, you have to specify the host name or the IP address of the working host via the --receiver-host option.
  • Clusters are managed with their own unique id. In previous version, a node unjoined from the Droonga cluster is still a member of the Serf cluster, and there is no information that protocol adapter nodes detect which is actual member or not.
• Droonga-http-server 1.1.0 and Express-droonga 1.0.8
  • Connects to active engine nodes of the cluster of the associated engine node correctly. Previous version unexpectedly kept connections to already unjoined engine nodes.

Conclusion

• Droonga 1.0.9 has been released!
• Some inconvenience limitations of cluster management commands are solved.
• droonga-http-server now works as you expected after cluster management operations.
• Droonga project will release a new version every month!
