Grails Immediate commit for objects in a transaction - mysql

Question

In my project there is a table called process_detail. Row inserted in this table as soon as a cron process starts and is updated at the end
of the cron process completion. We are using grails which internally takes care of transaction at service level method i.e. transaction starts at the start of the method, commit if the method execution successful, rollback if any exception.
Here what happens is that if the transaction fails this row also being rolled back this I don't want because this is type of a log
table. I tried creating a nested transaction and save this row and at the end update it but that fails with lock acquisition exception.
I am thinking of using MyISAM for this particular table,
this way I don't have to worry about transaction because MyISAM does not support it and it will commit immediately and no rollback possible. Here's pseudo code for what I am trying to achieve.
def someProcess(){
//Transaction starts
saveProcessDetail(details); //Commit this immediately, should not rollback if below code fails.
someOtherWork;
updateProcessDetail(details); //Commit this immediately, should
//Transaction Ends
}
Pseudo code for save and update process detail;
def saveProcessDetail(processName, processStatus){
ProcessDetail pd = new ProcessDetail(processName, processStatus);
pd.save();
}
def updateProcessDetail(processDetail, processStatus){
pd.procesStatus = processStatus;
pd.save();
}
Please advice if there is better of doing this in InnoDB. Answer could be mysql level I can find the grails solution my self. Let me know if any other info required.

Answer 1

Make someProcess #NonTransactional, then manage the transactional nature yourself. Write the initial saveProcessDetail with a flush:true, then make the remainder of the processing transactional, withTransaction?
Or
#NonTransactional
def someProcess() {
saveProcessDetail(details) // I'd still use a flush:true
transactionalProcessWork()
}
#Transactional
def transactionalProcessWork() {
someOtherWork()
updateProcessDetail(details)
}
