Class ClientRecord


@Internal public class ClientRecord extends Object
Represents the ClientRecord doc, a single document that contains an entry for every client (app) current participating in the cleanup of 'lost' transactions.

ClientRecord isn't as contended as it appears. It's only read and written to by each client once per cleanup window (default for this is 60 seconds). It does remain a single point of failure, but with a sensible number of replicas this is unlikely to be a problem.

All writes are non-durable. If a write is rolled back then it's not critical, it will just take a little longer to find lost txns.
