Bug ID: 9208
           Summary: LMDB feature request: variant of mdb_env_copy{,fd2}
                    that takes transaction as parameter
           Product: LMDB
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: ---
         Component: liblmdb
          Assignee: bugs@openldap.org
          Reporter: github@nicwatson.org
  Target Milestone: ---
The mdb_env_copy* functions create a read transaction themselves to run the
backup on.  New variants of these functions (one for mdb_env_copy2 and one for
mdb_env_copyfd2) would have a transaction parameter.  This transaction would be
used instead of creating a new transaction.
Application code could use these new functions to synchronize consistent live
backups across multiple LMDB instances (potentially across multiple hosts).
