Got to love unicode! Importing Ken Ishii’s Jelly Tones album (btw, I won it at Studio Brussel in Belgium sending an email through BBS, somewhere in 1995!) I saw following in iTunes: Found it pretty cool that ケン・イシイ shows up! I’m leaving as is. The Composer field is filled with ‘Ken Ishii’, so looking it up still works.
Selective restoring using ndb_restore
We’ve added some new options in MySQL Cluster 6.3.22 which makes it possible to selectively restore tables. The new options for ndb_restore are: --include-databases=name Comma separated list of databases to restore. Example: db1,db3 --exclude-databases=name Comma separated list of databases to not restore. Example: db1,db3 --include-tables=name Comma separated list of tables to restore. Table name should include database name. Example: db1.t1,db3.t1 --exclude-tables=name Comma separated list of tables to not restore. Table name should include database name.
OpenSolaris, Bazaar and SSH
Just a small tip for using Bazaar on OpenSolaris: set the BZR_SSH environment variable to openssh if you don’t have the Python module Paramiko installed. For example, in your ~/.bashrc: export BZR_SSH=openssh Could be useful if you’re pulling MySQL stuff from Launchpad and use (Open)Solaris. Could also be useful on other Unix-like operating systems when the default is missing (Bazaar uses Paramiko as default).
Feedback on MySQL Cluster talk at FOSDEM?
Today I gave an introduction talk of MySQL Cluster at FOSDEM 2009 in Brussels. The room was full and I didn’t see anyone dozing! A good feedback later on was to show more usecases. This a good point and I think on working on a talk showing less how it works, but how it can be used. Doing both technical details and use-cases is hard to do in 50 mintes.
NDB connection pooling in MySQL and Single User Mode
Since MySQL Cluster 6.2 it is possible to setup a pool inside the mysqld process opening multiple connections to a MySQL Cluster. This is pretty cool, but it might give troubles when you have to use Single User Mode. Take for example the following configuration for your SQL Nodes: [SQL] Id=10 Hostname= 10.100.9.6 [SQL] Id=11 Hostname= 10.100.9.6 [SQL] Id=12 Hostname= 10.100.9.7 [SQL] Id=13 Hostname= 10.100.9.7 No further slots are defined, and you setup your two MySQL Servers to use connection pooling:
