PGroonga 1.1.1 has been released

PGroonga (píːzí:lúnɡά) 1.1.1 has been released!

See PGroonga 1.0.0 release announce about PGroonga.


Here are changes since 1.0.9:

  • [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.
