Supported Debian 9 (stretch)

In this release, Debian 9 (stretch) has been supported!

Now install documentation is out for Debian 9 (stretch) users.

Added grndb log options

In this release, log options are supported for grndb.

grndb is a tool for maintenance Groonga database. It provides grndb check and grndb recover. But in the previous versions, grndb doesn't support logging options.

Use supported --log-level and --log-path option to save grndb logs.

Improved query performance

In this release, some query performance is improved. Here are some improved patterns.


    • Improved performance by reducing redundant process when accessing column data. Supported operators are ==, !=, <, >, <= and >=.
  • in_records()

    • Improved performance by reducing too many object creation. To avoid such a situation, implementation is switched from mruby to C.
