[Spread-users] Need advices

[Min Lu]

I am facing similar issues in our development. I am considering doing
similar thing
In Solaris as DRBD is doing in Linux . I wonder if anyone has tried that
before.

Like SNDR from Sun.

Subject: [Spread-users] Need advices

Hi,

I need and advice before to start a Spread project.

Ce goal of this project is to permit to run several MySQL servers in
clustering
mode to get high availability and high performances. The problem is
MySQL is the
multi-threading and the shared memory, at this time none clustring
system can run
multi-threading and shered memory apps.

MySQL has a db replication feature but only in one way master-->slave
then if the
master go down the whole cluster system down too, an second problem we
store files
up to 10Mb in the DB and replicate a such insert on 10 servers will
overload the
network.

What we are thinking: use Spread to multicast the insert, update,
delete, alter,
commands on all other nodes on the cluster but only once, then each node
listening
the spread messages replicate their base as soon as the message are
passed. With
this system we espect to got a realtime replication between 10 or more
MySQL
servers through the network with a minimum network overload.

My question is it possible to do that with Spread and to spread a
message up to
10Mb ?

Thanks in advance for your help.

Sam.
