Release 7.0.0 - 2017-02-09

Improvements

  • [in_values] Supported sequential search for reference vector column. [Patch by Naoya Murakami] [GitHub#629]
  • [select] Changed to report error instead of ignoring on invalid drilldown[LABEL].sort_keys.
  • [select] Removed needless metadata updates on DB. It reduces the case that database lock remains even though select command is executed. [Reported by aomi-n]
  • [lock_clear] Changed to clear metadata lock by lock_clear against DB.
  • [CentOS] Enabled EPEL by default to install Groonga on Amazon Linux.
  • [query] Supported "@X" style in script syntax for prefix("@^"), suffix("@$"), regexp("@^") search.
  • [query] Added documentation about available list of mode. The default mode is MATCH ("@") mode which executes full text search.
  • [rpm][centos] Supported groonga-token-filter-stem package which provides stemming feature by TokenFilterStem token filter on CentOS 7. [GitHub#633] [Reported by Tim Bellefleur]
  • [window_record_number] Marked record_number as deprecated. Use window_record_number instead. record_number is still available for backward compatibility.
  • [window_sum] Added window_sum window function. It's similar behavior to window function sum() on PostgreSQL.
  • Supported to construct offline indexing with in-memory (temporary) TABLE_DAT_KEY table. [GitHub#623] [Reported by Naoya Murakami]
  • [onigmo] Updated bundled Onigmo to 6.1.1.
  • Supported columns[LABEL].window.group_keys. It's used to apply window function for every group.
  • [load] Supported to report error on invalid key. It enables you to detect mismatch type of key.
  • [load] Supported --output_errors yes option. If you specify "yes", you can get errors for each load failed record. Note that this feature requires command version 3.
  • [load] Improve error message on table key cast failure. Instead of "cast failed", type of table key and target type of table key are also contained in error message.
  • [httpd] Updated bundled nginx to 1.11.9.

Fixes

  • Fixed a bug that nonexistent sort keys for drilldowns[LABEL] or slices[LABEL] causes invalid JSON parse error. [Patch by Naoya Murakami] [GitHub#627]
  • Fixed a bug that access to nonexistent sub records for group causes a crash. For example, This bug affects the case when you use drilldowns[LABEL].sort_keys _sum without specifying calc_types. [Patch by Naoya Murakami] [GitHub#625]
  • Fixed a crash bug when tokenizer has an error. It's caused when tokenizer and token filter are registered and tokenizer has an error.
  • [window_record_number] Fixed a bug that arguments for window function is not correctly passed. [GitHub#634][Patch by Naoya Murakami]
