Hi,
It's interesting to hear the experience with hardware load
balancers.
But I'm also interested to learn how everyone synchronises
(replicates) the software on their load balanced servers .... cron, ftp,
rsync?
Also does anyone have a variation on the traditional design of a
single dedicated database server sitting behind a bank of web servers?
The plan at Turbo10 is not to replicate everything - so only the
essential information is copied onto the search servers, and stored in
MySQL heap tables - this avoids extra trips to the database, and disk
seeks.
All transactions are first recorded in 'heap' tables (e.g.,
searchbucket, clickbucket) on the search nodes, then siphoned off to
master tables by a dedicated database machine.
