Transaction timeouts

[Zibfo]

Greetings all,

 

I have a groovy script ( not a service) that collects (scrapes) data,
processes, and submits to db. If there are too many records, no error is
thrown but transaction timeout causes no records committed.

Is there a way to call forced commits occasionally during execution to clear
and reset the transaction queue?

 

Thanks a bunch

Hi Max,

you can make use of TransactionUtil, see WebToolsService#entityExportAll
for an example.

The main pattern is

// start transaction

boolean beganTx = TransactionUtil.begin();

// iterate through generic values and store them, count numberWritten

...

    // commit after 500 values

    if (numberWritten % 500 == 0) {
        TransactionUtil.commit(beganTx);
        beganTx = TransactionUtil.begin();
    }

// commit remaining values

TransactionUtil.commit(beganTx);


Hope that helps,

Regards,
