[groonga-talk:332] [ANN] PGroonga 1.1.1

[Kouhei S. <ko...@cl...>]

Hi,

PGroonga 1.1.1 has been released!

  http://groonga.org/en/blog/2016/08/31/pgroonga-1.1.1.html

PGroonga is a PostgreSQL extension that makes PostgreSQL
fast full text search platform for all languages!

Here are changes since 1.1.1:

  * [Windows] Upgraded bundled Groonga to 6.0.8.

  * Improved the number of hits estimation. It helps that
    planner choose suitable index use or not index
    use. Therefore, total performance is improved.

  * Added pgroonga.match_positions_character function that
    returns match positions in character.

  * Added pgroonga.flush function that flushes buffered
    changes in memory.

  * Fixed a bug that needless recheck is ran on bitmap heap
    scan. If recheck is ran, performance is down.

In this release, performance is improved. Earlier PGroonga
releases are fast but you can get more performance
improvement by just upgrading to this release. Let's try
PGroonga!

## How to upgrade

This version is compatible with 1.0.9 and 1.1.0. Upgrade by
steps in "Compatible case" in Upgrade document:

## Group chat that supports full text search by PGroonga

Do you know Zulip(*1)? It's an open source group chat. It's
open source-ed by Dropbox(*2).

(*1) https://zulip.org/
(*2) https://blogs.dropbox.com/tech/2015/09/open-sourcing-zulip-a-dropbox-hack-week-project/

Zulip supports full text search but it only supports
English. Zulip now supports PGroonga based full text search
feature. It supports all languages.

Zulip doesn't release a new version that includes PGroonga
support. But you can start using Zulip. You can upgrade
after installing Zulip.


Thanks,
