I wonder what the best way is to get a feature request more visibility (convert a feature request to an actual work item).We use replicate-do-db on all our slave servers , so after many, many, restarts of our slave servers, I checked the bug list for any feature requests surrounding this, and about 6 months ago, one was opened: replicate-* rules should be dynamically configurableSadly,
I wanted to point out something that might not be obvious from
the name: MySQL Parallel Dump can be used as a generic wrapper to
discover tables and databases, and fork off worker processes to
do something to them in parallel. That "something" can easily be
invoking mysqlcheck -- or any other program. This
makes it really easy for you to do multi-threaded
whatever-you-need-to-do on MySQL tables. Here's how.
I'm trying to automate some trivial maintenance tasks for my own
MySQL server, and trying also to minimize the effort, so ... Here
is the recipe:
Take an excellent generalized stored procedure like the one by
Konstantin Osipov, see "Dynamic SQL is Stored Procedures" on MySQLForge
(example 4).
Tune it a bit so that it takes into account only non system
tables (I'm trying to turn it into something similar to
Microsoft's sp_MSforeachtable), here is the code:
- DELIMITER $$
- DROP PROCEDURE IF EXISTS `test`.`sp_4_each_table` $$
- CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_4_each_table`(db_name VARCHAR(64), template VARCHAR(21845))
- BEGIN
- #
- DECLARE done INT DEFAULT 0;
- #
- DECLARE tname VARCHAR(64);
- #
- DECLARE c …
