To set the keypoint interval
Keypoint operations
compress the transaction log file. The keypoint interval is the number of transactions between keypoint operations
on the log. Keypoint operations can reduce the size of the transaction log files.
A larger number of keypoint intervals (for example, 2048) results in larger transaction
log files, but fewer keypoint operations, and potentially better performance. A smaller
keypoint interval (for example, 256) results in smaller log files but slightly reduced
performance due to the greater frequency of keypoint operations.
