Groonga is a fast and accurate full text search engine based on an inverted index. Newly registered document instantly appears in search results, and updates are allowed without read locks. These characteristics result in superior performance for real-time applications. It is also a column-oriented database management system (DBMS). Compared with well-known row-oriented systems, such as MySQL and PostgreSQL, column-oriented systems are more suited for aggregate queries.
Release Notes: API documentation has been added. Experimental new groonga-httpd are supported: groonga_log_path, groonga_log_level, and groonga_cache_limit. They are used to customize log path, log level, and cache limit for the query cache.
