checkpoint transactions nn

This option indicates how many transactions must be committed to the temporay log file before performing a checkpoint that commits ongoing transactions to disk.

The smaller the number of transactions, less efficient will be the overall performance of the system, but the databases involved will be more often updated.

If the number of transactions is big, ZIM Backup Server, if running, will take more time to perform the backup process. Also, depending on the number of buffers updated in each transaction, the temporary log file size can vary significantly.

Regardless of the number of transactions, in case of a disk crash, ZIM server will automatically recover all consistent transactions present in the temporary transaction file.

A checkpoint is triggered whenever the number of checkpoint transactions or the number of checkpoint buffers happens first.
