Working on OAK-9447 - trying to upgrade the obsolete java-mongo-driver with latest mongodb-driver-sync

[Raffaele Gambelli <Ra...@cegeka.com.INVALID>]

Hi all,

 on stated in subject, I'm trying that upgrade, as you know mongodb-driver-sync has no CVE, is simpler, is mantained and is much more performant.

I would like to share with you that the code in MongoDocumentStore like this:

if (secondariesWithinAcceptableLag()) {
               dbCollection = getDBCollection(collection);
           } else {
               lagTooHigh();
               dbCollection = getDBCollection(collection).withReadPreference(ReadPreference.primary());
           }

will be replaced simply with this:

dbCollection = getDBCollection(collection);

because mongodb-driver-sync knows itself if ask to primary or secondary based on maxStalenessSeconds property (https://www.mongodb.com/docs/drivers/java/sync/current/fundamentals/connection/connection-options/)

ReplicaSetStatus class too has not much more sense I think, for sure its method updateLag

Have you some opinion you want to share?

Bye
