Consider some of cases:
- When domain fails to save data because of duplicate record.
- When an unsaved domain belongsTo a domain, then showing: 'save the transient instance before flushing'.
Here is example of my thread creation:
Thread.start {
Domain.withTransaction {
// Doing stuff and calling synchronization method to write data to DB
}
}
Fix was found here: Grails, GPars and data persistenceI replaced "Domain.withTransaction" with "Domain.withNewSession":
Thread.start {
Domain.withNewSession {
// Doing stuff and calling synchronization method to write data to DB
}
}
and save(flush:true) start writing into mySQL. Since data is written
to mySQL, findBy... start returning proper results and therefore I
application doesn't try to create duplicated record anymore. Issue
solved!
