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).
