Use mysql-udf-http and lib_mysqludf_json synchronizes the update to Tokyo Tyrant with MySQL Trigger.
(1). Download and install lib_mysqludf_json:
On 32-Bit Linux:
wget http://mysql-udf-http.googlecode.com/files/lib_mysqludf_json-i386.tar.gz
tar zxvf lib_mysqludf_json-i386.tar.gz
cd lib_mysqludf_json-i386/
# if your MySQL install path is not '/usr/local/webserver/mysql/', please modify the path.
cp -f lib_mysqludf_json.so /usr/local/webserver/mysql/lib/mysql/plugin/lib_mysqludf_json.so
cd ../
On 64-Bit Linux:
wget http://mysql-udf-http.googlecode.com/files/lib_mysqludf_json-x86_64.tar.gz
tar zxvf lib_mysqludf_json-x86_64.tar.gz
cd lib_mysqludf_json-x86_64/
# if your MySQL install path is not '/usr/local/webserver/mysql/', please modify the path.
cp -f lib_mysqludf_json.so /usr/local/webserver/mysql/lib/mysql/plugin/lib_mysqludf_json.so
cd ../
Enter to the MySQL console:
/usr/local/webserver/mysql/bin/mysql -S /tmp/mysql.sock
mysql>
create function lib_mysqludf_json_info returns string soname 'lib_mysqludf_json.so';
create function json_array returns string soname 'lib_mysqludf_json.so';
create function json_members returns string soname 'lib_mysqludf_json.so';
create function json_object returns string soname 'lib_mysqludf_json.so';
create function json_values returns string soname 'lib_mysqludf_json.so';

(2). Create table:
mysql>
SET NAMES UTF8;
USE test;
CREATE TABLE IF NOT EXISTS `mytable` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`addtime` int(10) NOT NULL,
`title` varchar(255) CHARACTER SET utf8 NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
(3). Create trigger for table:
mysql>
/* TRIGGER for INSERT */
DELIMITER |
DROP TRIGGER IF EXISTS mytable_insert;
CREATE TRIGGER mytable_insert
AFTER INSERT ON mytable
FOR EACH ROW BEGIN
SET @tt_json = (SELECT json_object(id,addtime,title) FROM mytable WHERE id = NEW.id LIMIT 1);
SET @tt_resu = (SELECT http_put(CONCAT('http://192.168.8.34:1978/', NEW.id), @tt_json));
END |
DELIMITER ;
/* TRIGGER for UPDATE */
DELIMITER |
DROP TRIGGER IF EXISTS mytable_update;
CREATE TRIGGER mytable_update
AFTER UPDATE ON mytable
FOR EACH ROW BEGIN
SET @tt_json = (SELECT json_object(id,addtime,title) FROM mytable WHERE id = OLD.id LIMIT 1);
SET @tt_resu = (SELECT http_put(CONCAT('http://192.168.8.34:1978/', OLD.id), @tt_json));
END |
DELIMITER ;
/* TRIGGER for DELETE */
DELIMITER |
DROP TRIGGER IF EXISTS mytable_delete;
CREATE TRIGGER mytable_delete
AFTER DELETE ON mytable
FOR EACH ROW BEGIN
SET @tt_resu = (SELECT http_delete(CONCAT('http://192.168.8.34:1978/', OLD.id)));
END |
DELIMITER ;
(4). Select data from MySQL table and Tokyo Tyrant:
mysql>
SELECT id,addtime,title,http_get(CONCAT('http://192.168.8.34:1978/',id)) AS tt FROM mytable ORDER BY id DESC LIMIT 0,5;
mysql>
drop function http_get;
drop function http_post;
drop function http_put;
drop function http_delete;
