Multiple grails app instances supported

Hi,

I am getting duplicated sequence number when running sequence generator in the multi-instances environment. Can it support clustered environment? If no, are they any work around to resolve this issue? Thanks.

If you read https://github.com/goeh/grails-sequence-generator#known-issues you will see that the default sequence generator uses in-memory sequences and cannot be used in clustered environments.
There is a Redis implementation that works in clustered environments here https://github.com/goeh/grails-sequence-generator-redis
But that plugin is not in the official plugin repository so you have to build it yourself and install it in your local Maven cache with grails maven-install.
