Can we restore the completed and incomplete transactions from transation_log when the system crashes in between write/update/delete operations?

How to restore completed and incomplete transactions from transaction log when the system crashes. What is the strategy for backup in transaction failure or system failure back up?

When you restart SingleStoreDB after a crash, it recovers all databases to a transaction-consistent state. It’s automatic. You don’t have to do anything to get it.

Backup is separate from transaction recovery.

Internally, the system uses “snapshots” and a write-ahead log to perform transaction-consistent restart recovery.
