It provides [grndb check](/docs/reference/executables/grndb.html#check) and [grndb recover](/docs/reference/executables/grndb.html#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. + +* `FIXED_SIZED_COLUMN OPERATOR CONSTANT` + + * 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. + + +### Conclusion + +See [Release 7.0.4 2017-06-29](/docs/news.html#release-7-0-4) about detailed changes since 7.0.3. + +Let's search by Groonga! -------------- next part -------------- HTML����������������������������...Download
