I see a statement in the forum in the checkpointing section --> "Each wr

The most recent applicable *.kdb file

Hi Myles, the documentation is a little confusing. If you say that the transaction log is the most recent applicable *.kdb file, then it means that the write transaction is applied to the engine in memory and to the most recent applicable *.kdb file. Then what does checkpointing do? It says --> "When a checkpoint completes, the transaction log is applied to the database and the transaction log is cleared". If transaction log = most recent applicable *.kdb file, then it would mean , When a checkpoint completes, the most recent applicable *.kdb file is applied to the database and the most recent applicable *.kdb file is cleared. Please explain. Does checkpointing create only a new .kdb file? But then why do we need to create a new .kdb file if every time a write transaction is applied immediately to the engine in memory as well as the most recent applicable .kdb file?

"When a checkpoint completes, the transaction log is applied to the database" --> In this statement, what is the database? Is it KDB?

Somebody who has no knowledge about Appian, wouldn't understand what is checkpointing with this documentation.

Please explain clearly.

There is a difference between applying a transaction and saving a transaction. What goal are you trying to achieve? We also have an administration class available.

Please explain the difference between applying a transaction and saving it. I am just trying to understand the documentation. There is no other goal. Please explain?
