    cache.region_prefix = "hibernate"
}

You can configure in your Config.groovy the following properties.

redis {
   // Connection details (default: localhost:6379)
   host = localhost
   port = 6379

   // Connection timeout
   timeout = 2000

   // Password to access Redis (optional)
   password = secret

   // database for hibernate cache (default 0)
   database=1

   expiryInSeconds {
       // hiberante 2nd cache default expiry (seconds)
       default = 120

       // expiry of hibernate.common region (seconds) // hibernate is prefix, region name is test.Author
       expiryInSeconds.hibernate.test.Author = 0

       // expiry of hibernate.account region (seconds) // hibernate is prefix, region name is test.Book
