When checkpoint should be appended in the stored procedures












-1















i would like to know what is the proper moment to append CHECKPOINT manual in the stored procedures (or function if it is proper too)



As i didn't see anything different apparently after the CHECKPOINT is appended.



Thus i cant illustrate if the checkpoint is applied correctly.



Usually, under what kind of situations CHECKPOINT should be added?



Please provide an example with reason that CHECKPOINT should be added to optimize the performance or it is good practice to do so.



Thanks

          What are you hoping to achieve?



          A CHECKPOINT flushes the dirty pages from memory to disk and records some internal information to know where it can then recover from in the event of crash recovery.



          The process runs in the background periodically - so unless you have a real need to flush pages from cache then there usually is no need to issue a manual one.



          However, as I don't know your specific circumstances, it is not possible to say if you have any need for this.

          • It depends on what you want to achieve. There are no fixed rules to say issue a CHECKPOINT in these scenarios. Either you rely on the automatic checkpoint process to flush your pages to disk, or if you find that for whatever reason that you need to control this process more granularly then issue a CHECKPOINT as required. docs.microsoft.com/en-us/sql/relational-databases/logs/…

          • you don't need to know what i wanted (as i wanted nothing, i just want to know the usage of checkpoint). you can provide your example which applied checkpoint, and describe what you intended to achieve in your example

          • That wasn't a comment on when not to issue a CHECKPOINT, it was identifying what a CHECKPOINT does and therefore if you have a scenario that fits that then use a manual CHECKPOINT, otherwise there is unlikely to be any value to your database by using one. CHECKPOINT does not impact performance in any way - modifications are still made initially to the Buffer Pool and then later flushed to disk. You will not see a performance difference at all by using CHECKPOINT
