What do you mean by checkpoints in DBMS? |
|
Answer» When MANY transactions are executed at the same time, then the LOGS are interleaved. As a result, it becomes tough for the recovery system to recover the data. Checkpoint acts as a bookmark that MAKES the inspections during the transaction execution. Each checkpoint, the previous logs are removed from the system and are STORED in the storage disk. As a result recovery of the data is faster. |
