Employee_Team +4 Vote Up -0Vote Down

 

Well actually….no. The second Development Milestone Release of MySQL Cluster 7.2 introduces support for what we call “Multi-Site Clustering”. In this post, I’ll provide an overview of this new capability, and considerations you need to make when considering it as a deployment option to scale geographically dispersed database services.<?xml:namespace prefix = o />

SkySQL adds MySQL Cluster training to the offering
+1 Vote Up -0Vote Down

Very soon after SkySQL Ab was created, we added an Advanced MySQL Cluster course to our training offering. This addition was made as a customer who was already quite experienced with MySQL cluster wanted training. This course was, however, deemed to be too complex and with too much pre-requisites to add to our public offering so it was left as a special treat for customers who had deep cluster knowledge. We decided that we would instead create a more general purpose MySQL Cluster course with less prerequisite knowledge required as soon as possible.
Many months have passed and a lot of other courses have been created since, but we now finally release our …

LRU follow up
+0 Vote Up -0Vote Down

Due to one of the machines being configured a little bit too close to the edge we had to restart it to downsize its innodb_buffer_pool_size a little bit. We tested the innodb_lru_dump_restore directive with this machine. Results were very promising: it wrote the dump every 5 minutes (we set the variable to 300 seconds) and after MySQL had restarted it reloaded the dump.

However: since MySQL is already started fully before it even starts to load the LRU dump it means MySQL is already available to the outside world. This means in a HA environment it would already be going to perform poorly due to the torrent of queries coming in. This means either the loading …
