The characteristics of groonga
==============================
-The successor to the Senna that is an embeddable full text search engine
-------------------------------------------------------------------------
+The successor to Senna
+----------------------
-Groonga is developed as the successor project to Senna. Senna is an embeddable full text search engine and it is used widely. Groonga takes over from Senna's characteristics that are fast, high precision and high flexibility. We started to develop groonga to improve those Senna' characteristics.

+Multi-protocol support
+----------------------
-Senna is an component for an application that supports full text search. Groonga can be a server that provides search service. The groonga server supports HTTP, memcached binary protocol and gqtp (groonga query transfer protocol). Clients can search by those protocols via TCP/IP connection. It makes easy to use on a rental server that can install a library.

This feature makes it easy to use groonga on a rental server that doesn't allow users to install a library.

-Senna that is predecessor of groonga is a full text search engine without storage. Senna was commonly used with MySQL or PostgreSQL. Tritonn is a custom MyISAM storage engine that uses Senna as full text search engine. Ludia is a extension module for a PostgreSQL to use Senna as full text search engine. But those approaches can't fully utilize the performance characteristics of Senna. Senna can update index without read lock.
+Senna, the predecessor of groonga, is just a full text search library and is generally used with Tritonn or Ludia to provide various services. Tritonn is a custom MyISAM storage engine that uses Senna to support full text search. Ludia is an extension module for PostgreSQL to use Senna.
-For example, MyISAM acquires table lock while updating records in many cases. In those cases, data update by MyISAM is a bottleneck however Senna updates an index full text search fast.
+However, Tritonn and Ludia cannot fully utilize an important characteristic that Senna can update an index without read locks. For example, MyISAM uses a table lock while updating records in many cases. The table lock prevents clients from reading records even though Senna is read lock-free. This becomes a bottleneck of the whole system.
-Groonga implements a storage that doesn't acquires read lock to realize search service that has immediacy.
+To cope with this problem, groonga has its own storage engine that doesn't require read locks. Groonga is thus suited for real-time applications.
+Sharable storage
