MySQL persistence strategies Openhab

// persistence strategies have a name and a definition and are referred to in the "Items" section
Strategies {
	everyHour 	: "0 0 * * * ?"
	everyDay 	: "0 0 0 * * ?"

	// if no strategy is specified for an item entry below, the default list will be used
	default = everyChange
}

/*
 * Each line in this section defines for which item(s) which strategy(ies) should be applied.
 * You can list single items, use "*" for all items or "groupitem*" for all members of a group
 * item (excl. the group item itself).

	// persist all items once a day and on every change and restore them from the db at startup
	// careful, this might result in huge databases - that's why it is in comment here ;-)

	// persist all temperature and weather values at every change and every hour
