I'm not sure if many databases offer this, but you can do it in foundationdb like this: version = txn.get_read_version().wait() compute_something(version) Then on the remote computer, you can create a new transaction and call: def compute_something(version): txn2 = db.create_transaction() txn2.set_read_version(version) # ... Then use the transaction as normal. This will ensure both transactions are looking at the same snapshot of the data in the database.
