[NETVIRT-1075] NeutronvpnUtils: handle transactions with jobCoordinator to avoid blocking

Mon, 25 Nov 2019 07:36:43 +0000

Now we are using in NeutronvpnUtils: updateVpnInstanceOpWithType blocking transaction:

VpnInstanceOpDataEntryBuilder builder = new VpnInstanceOpDataEntryBuilder(vpnInstanceOpDataEntry);
builder.setBgpvpnType(choice);
WriteTransaction writeTxn = dataBroker.newWriteOnlyTransaction();
writeTxn.merge(LogicalDatastoreType.OPERATIONAL, id, builder.build(), false);
LOG.debug("updateVpnInstanceOpWithType: sent merge to operDS BgpvpnType {} for {}", choice, vpn.getValue());
try {
writeTxn.submit().get();

....

And the same in some other methods.

It will be better to refactor NeutronvpnUtils, and to use async transactions handeled by jobCoordinator as much as possible, to avoid blocking
